Back in the early 80's I built a '67 Chevelle with a big block 402 with straight 3" pipe back to the mufflers and into dumps which is illegal in my state, in a one in a million chance not long afterwards a car load of State Trooper rookies were in citation training and pulled behind me as I feathered the throttle so quietly but they pulled me over and cited me for the illegal exhaust dumps, I was so pissed and didn't want to have to change anything but after seeing that they didn't put the year or model on the inspection citation other than Chevy 2 door with my tag number I swapped my tags onto my Wife's 2 door Chevy Vega which had a brand new exhaust system with the labels still intact and took it to the inspection station saying I just replaced everything and they signed off on it, I swapped my tags back on the Chevelle when I got home, drove it for years, and never got another citation after that. 😅

From personal experience, my Chevelle with cherry bomb single chambers had dumps temporarily and it sounded a bit more tinny and rowdy, when I added the tailpipes it gave a more deep loud tone. On my squarebody long bed, I put 28” glass packs on and temporarily ran it without tailpipes and it had a deep and lazy sorta sound to it, but once I put the tailpipes on it, it gave it that Glasspack rasp/echo and actually made the truck much louder. Both those engines were small blocks with cam/heads/ect. So they were moving some air vs stock. I think it depends on muffler combo, length of the tailpipe in relation to where the muffler is under the car, and lastly the overall length of the vehicle, (meaning how long the whole system is). Either way, your car sounds great with or without in my opinion
@@billys4625 to be totally honest they were just sitting on my shelf from an old shop closeout I got them from, free is for me. I also wanted the tone to be a little more mild seems it’s a truck that I’d like to drive frequently, still pretty loud once you open the secondaries but part throttle driving is pretty tame and rumbly.
Currently have dumps on my 408 LS swapped 70' Chevelle, just to get it on the road to break it in. Love the sound but I can't drive with the windows down for more than 15 minutes due to the fumes. Dumps make for great smoke shows too if they are angle out corrrectly!
That is the legal point in most states. Must exit rear of the cabin as in to not leak in the cab. Anything farther forward, I m not thinking about getting in it
Love the sound of turn downs.. However, behind my .060 bored 400ci pontiac, I had 3" collectors into 3" pipe into 3" Flowmasters into turn downs. Sounded aces !! Ran 13.0 in QM all day long. I took off turndowns and added 3" pipe from mufflers over rear and all the way to bumper. I ran 12.4s all day long. I realize its a sound choice for many. But its a key part of performance tuning too.
I had a Camaro that I did dumping before the rear axle and had it redone to over the rear axle and out the back. It ran the same consistently either way, and I wasn’t smelling exhaust fumes anymore.
Just got done my Sonoma exhaust a few days ago that I dumped in front of the rear axle, 3.5" collectors back to 3.5" Flow Master Flow FX to dumps, i'll be installing my electric cutouts in the spring. My cam really makes them come alive.
I did the same thing on my 383 SBC in my C10. It was dual, routed over the axle and side exit previously. It actually changed the idle behavior and I feel like it was louder before. I notice no difference in fumes, it smelled like a boat either way. 😁
I'm with you, I also like loud aggressive exhaust. Just hope that you have understanding police officers where you live because it could cause issues if you dont.
I have always been a fan of the dump style exhaust where the sound is bouncing off the ground and underneath the car. If you do the dumps more torwards the back of the car, like near the rear differential, the fumes will be far less inside of the cabin. I usually do dump exhaust near the rear differential and use glasspacks as the mufflers and it sounds good. I’ve never been a fan of Flowmaster. Something about those Glasspacks just hit different on dumps.
That's a sick 57 ,I used to run both , I'd run dumpers with the tailpipes to the rear but with removable caps ,for the drags or 1/8th mile racing easy 3 bolt removable caps are the go !!
I tend toward rear end ratios in the 4.56 - 4.86 range, and I do highway driving a bit as well, steady cruising in the 4K-5K range, so tail pipes make it entirely possible, any exhaust ending underneath the car creates droning which is incredibly tiring
I love the sound of dump pipes, but I also dig hearing that chop in the back. I'm building a 60 El Camino with a somewhat healthy 427 sbc, 4 speed. I've got 3" round Flowmasters and plan on running them over the rear to exit behind the rear tires.
I drove a 68 396 Camaro with an L88 solid cam, then a ZLX cam in it with Cherry Bombs right after the Hooker headers and 18 inches of pipe, on the street for a few years and never had an issue. It was a bit loud, but it was in 1978-80 Tuscaloosa Alabama
Pointing the tips at the ground is quieter, it points the sound waves down and they spread out. Point them out the sides or straight out the back and they are a lot louder; the sound waves are pointed right at people.
Those are turn downs right after the muffler. A dump is before a muffler and is either an electric dump or you will manually have to take off 3 bolts to open the dump to bypass the muffler and the entire exhaust. Car Sounds good.
We've always called these short turndowns dumps and the electric or manual openings before the muffler cutouts. Might be a regional thing, or we're just dumb over here 😂
@@sneakypete129 yeah probably. It’s how it is in Summit Racing and in Jeg’s catalog is why I said it. Maybe it will help someone when ordering. Good video. Thanks for sharing.
“Dumps” had me confusing them with cut-outs. Most of the glass pack-equipped cars I remember from high school basically had a Cherry Bomb or a knockoff hanging off the pipe right behind the cat, no tip. There was a classmate or two who actually had something more potent than a smog motor under the hood with the glass-pack dump setup that was sufficiently loud. I had a mid 70s European sedan with a straight six that got the single outlet muffler removed and a straight pipe run off the resonator, over the axle, and straight out the back. It had a fairly wide RPM range and could rattle windows from 2-3000 revs. While obviously not an uncorked big block, it was enough to annoy dormitory residents in college.
To me, there isn’t really any noticeable difference between the two and both sound great. If you have any holes in your floor pans, I would definitely go with the tailpipes. Carbon monoxide poisoning isn’t fun. If it doesn’t kill you, it will make you feel like shit and it takes some time to recover from it. I worked at a shop when I was much, much younger and the two other mechanics and started feeling sick, like maybe there was a flu going around, and the symptoms got worse. Terrible headaches, dizziness, and I even puked a couple times. No one outside of work got sick, so it didn’t seem like a virus. I mentioned to a doctor that was a good customer what was going on and he said it sounded like carbon monoxide poisoning. Turned out the exhaust system in the main shop had a piece of the ducting come loose and the exhaust fumes from the cars we ran inside the shop was coming right back in. The leak was in my corner stall so I guess I got it worse. It took a good month after we all had blood test confirming we did have carbon monoxide poisoning before I started feeling better. BTW, when I did state vehicle inspections, a tail pipe was described was exhaust piping that extends past the axle. Side pipes were illegal in my state unless they came that way from the factory.
@@TheCrazyMoparDude68 I appreciate your words and experience on the matter. The way it's set up right now is not safe for any extended periods of driving, which I don't really do. However, if that changes I will be sure to make whatever changes needed to keep myself safe. Thank you for taking the time to tell your story and give me that info.
There is a massive difference in sound when the car is on jackstands versus being on the ground, ESPECIALLY with dumps. I prefer the sound and look of dumps, but as I get older (50 now), tailpipes are becoming more appealing.
Turn the dumps to the side the are a lot more menacing plus it is louder since the sound can travel futher have a nova II with a built merc 454 headers to cherry bombs down the rockers when I crack the throttle people jump
I've got dumps on my 1971 455HO(for the moment). Sounds great, but the problem is on sandy places, it make a hell of dust clouds around and in the car ...
You can always go side exit just behind the rear tire. I had a 400 SBC with 3 inch exhaust and x-pipe exiting behind the tire on both sides and you get the best of both worlds. You can still hear it and no more fumes/and kicking dust up.
Wow《☆》Nice patina👍🏾🍺🤳Sounds great both ways. Saving weight without exhaust pipes. I'd probably go for a full exhaust system with X pipe to see if it gains any performance. All the extra weight is near the rear axle & may help with traction✌🏼😎☯️
Dumps is better but you need to put an H pipe 14 inches back from the collector. This will provide a much better sound and pick up a couple of horsepower and torque. Trust me it will sound much better with the H pipe deeper tone of power.
The 57 is super ! Does it go Down the track ? If so what does it run ? On the exhaust I like over the axle because I have a half mile of gravel drive to get to pavement. Otherwise, we should have the sound that we like, to scare people with 😎
When I was a teen, my car had a leaking exhaust manifold gasket. That led to me discovering the the joys of carbon monoxide poisoning by once suffering from nausea and vomiting. I strongly suggest getting your exhaust into the airstream. Chronic low-level exposure can cause heart, lung, and brain damage.
That engine is so rowdy that they "tailpipes" really didn't make much difference in the sound. Now the exhaust smell issue is another story. I was running headers/short mufflers and dumps that came to the middle of the door. Every time I drove the 55 I could smell the exhaust. I added 4' of pipe and it now the end is in front of the rear wheels. Still loud but no smell.
@@bigblockkings1031 Yeah I hear you, after doing this test I've decided im gonna move those turndowns back another foot or so, just so they aren't right directly under me.
For a street car, full exhaust out the back. Runs better, makes more low and mid range power. Street strip car cut offs. I've had more hot rods than I can count and full exhaust was always better.
Used to run turbos n turndowns for decades, love that sound! If it werent for the laws id do it again today but dont wanna give them more reason to pull me over. Tailpipes to rear, 45 dg turndown rear bumper. With our latest stupid Ca noise laws. putting 22" case superturbos on, same tailpipes. Maybe elec cutouts if I get the itch but prolly not. Thats another ticket. lol Muffs are more about sound, not much to gain there.
It's not all about sound, there are performance considerations, no? Doesn't the length of the exhaust affect the performance of the engine? Signal at carburetor?
It all depends if there is significant drone inside the car. I had a 305 with a mild cam and heads and had the exhaust dumped at the axle and flowmaster 40 series mufflers with no crossover pipe and it was decent. Hardly any drone and it had a good sound.
@@ck4181 Had those on a number of cars since the mid 80s . Drones way out of control, crossover or not didnt matter Back then if you had a stock engine and loud mufflers car guys would give you chit, yell poser at lights etc lol
Serious questions for you young man. 1. Do you think my 331 Sbc solid lift roller .575 with 1.5 roller rockers, 255/255 duration at .050, 110 LSA, 64cc aluminum Brodix 2.08/1.60 .700 lift springs/10 degree keepers, 5.5 cc dome etc. etc. etc. mouse could benefit/run well/not be a pain to drive on the street with 3.55 and a t56 speed, if I put on a dual quad setup like yours? Or should I stay with my old school Weiand 7508 single plane and circle track 650 Holley/no choke horn setup? I’m itching like a high schooler with crabs 🦀 to run a 2x4 setup. Low or high rise. Thoughts? Don’t care about rpm ranges, it sees ALL OF THEM! 😂 not worried about a loss of torque or hp here or there, just want to know if I can still drive it 5 days a week if I so chose to terrify all who dare to leave their homes without checking with me first. 😊 thank you kindly in advance for your 57 driving, balls worthy advice. Also 2. Did you do the dirty rag aluminum to magnesium wheel conversion? The wheels look like I went back to the 60’s at a gasser event in my not for rent/sale Time Machine. My favorite TH-cam car!
@@grendel.6.531 1. You can definitely drive with dual quads on the street, but it will take some time and work to get it dialed in right. If you're a pretty savvy tuner you won't have too many problems. I can guarantee you will have bogs, flat spots, backfires etc. but if you know what to do to solve those issues, you'll be fine. The only other issue is cold starts, takes a while to even get mine to idle on its own, and it's popping and chugging if I start driving before it's warm. 2. The wheels on the car in these videos are real American Racing magnesium wheels, however, they do have some graphite spray treatment because the front wheels patina doesn't match the rears, so I use the graphite to darken them to look the same. 3. Thanks for the compliments and watching the vids, I appreciate it.
@@sneakypete129 thank you for sharing your experience! I can deal with some tuning to look 👀 cool like your car! Also, try adding a couple O2 sensors before the mufflers and a gauge will help you dial in the carbs/linkages if you’re experiencing some of those issues. Bad ass car man! I loved those Bullets on it!
There are two problems with " dumping " the exhaust out right after the mufflers , first off , everything behind the pipes gets covered in soot , as do you when you have to work on it . Second , and more importantly , after while the combination of exhaust heat and the moisture from the condensation , will rot out your floors faster . Iitt takes several years , but you will learn how badly you screwed up .
I never encountered that problem because I learned how to tune a carb (okay, before I learned to tune a carb…maybe… 😅) and, I also am a true hot rodder who likes to spend time with his babies and of course my German Shepherd (who will absolutely NOT EVER leave my side….or fail to lay right where I am working…) oh yeah, my babies (cars) washing them even if it’s to bring out the patina more. Not bashing you, just pointing out that if that carb ain’t right, what you said WILL happen eventually. You might have just helped a few people out by mentioning this. 🇺🇸👍
@@grendel.6.531 in case you are under the delusion that I know nothing about this little game called " run what ya brung " , my last engine before my vision problems set in , was a .060 over 427 BBC , with 12.5 to ones , open chamber World Products heads , and a GK split cam . 627 @ 332 intake , and 629 @ 340 exhaust . The vision problem , you want NO part of . It called ' detached retinas ' . The very condition that caused Garlits and Amato to quit running Top Fuel .
PA, and I'm sure most states, says that the exhaust must be a sealed system exiting rearward of the passenger compartment. Now that that's out of the way.... I'll share some knowledge from memory and I hope I remember it all correctly. From a performance / drivability standpoint, some mufflers want tail pipes. At least 18", sometimes longer. Some mufflers, like the typical "turbo" muffler don't care. I know Flowmasters like tailpipes. I forget what glasspacks like. The issue is the pressure waves. The negative pressure wave that scavenges the exhaust starts at the first significant change in exhaust diameter. This is typically the muffler. This is where the "engines need backpressure" myth starts. People would remove the muffler and go straight pipes out the back and they significantly extended where the negative pulse starts. Flowmasters like tailpipes because they are tuned to scavenge the muffler, so the inlet is what the engine sees, but without a tailpipe the muffler backs up with pressure. This is similar to the intake in that the longer the distance, the lower in the RPM band it likes. With most mufflers it's just the muffler placement that matters, the length of tailpipe doesn't. I was never into glasspacks overall, so I really can't remember but I think they're different than most in that they do not start the pulse at the muffler. So dumps are preferred. I do see you have fender well headers with cutouts, but street performance and drivability are still a thing. Just keep it in mind that the type of muffler and tailpipe selection can have an affect. 30hp+ losses aren't uncommon for really messed up systems. With that out of the way, tailpipes or dumps are going to affect the cabin noise mostly. Dumps under the car will cause it to drone inside. I was never a fan and only ran dumps on trucks. Cutouts are a different story... Dumps, or any under car exit will create more of a deep boomy sound and kill the burble. But, turning down at any point and bouncing the sound off the ground will kill the burble to some degree. Think of the old Camaro exhaust that exited right after the rear wheel and pointed mostly down, angled out. Take that same exhaust and turn it and run it out the back and it sounds very different. How about, 45 degree out after the muffler, then turndown in front of the rear tire, still under the car? I like to point them an inch or two in front of the outside corner of the tire and "45 degree" is a suggestion - you may need more or less. The idea is to bounce the sound off the ground under the car but get the flow outside the car. It also looks really cool during burnouts. At the end of the day it's your car, so do what you like. No matter what you do it's hard to argue with a tunnel rammed SBC in a 57 Chevy... Good looking car and that small block sounds wicked.
The burble you speak of is exactly what I don't want. Again, just personal preference. As for the performance aspect, we will get into that more in videos to come. Right now I'm primarily focused on the sound and experimenting with that. Lots of good info you provided though.
Even with the dumps it doesn't sound that aggressive because it's got mufflers. Long tube headers with no mufflers would give it a REALLY aggressive sound. But why not include an X-pipe? All crossplane V8s scavenge better with an X-pipe, so they make more power and torque.
I don't dump exhaust unless i need to. full pipes all the way I'll tell you where it makes a BIG difference chambered mufflers. they always sound better with tailpipes
For a long time in Texas dumps were illegal. Not that anyone followed inspection laws. The law states exhaust must exit from under the vehicle. And now it’s changed. Now it says it must exit past the passenger compartment. That would make SUV’s and cars with dumps not legal, pickups I guess are ok. It screams lazy and to loud cause the sound echos off the ground and back to the vehicle and just makes it louder inside the vehicle. And if you ever decide to take the girl or wife or significant other or kids with ears that have not been abused for 40 years it’s not good for them. My 74 Camaro goes all the way to the back, I think the old muffler insulation is gone. It’s and old set of turbo mufflers. Yeah it’s loud. The truck exits in front of passenger side rear wheel. It’s also loud. Almost to loud, at highway’s speed it’s loud, but sounds good. I have never liked dumps, it just seems unfinished. And it gets exhaust all over everything under neath. Dumps are just not cool. I just do not like them.
With so much talk of tailpipes I had to hear for myself. Just a quick test, kinda half ass but it gives you an idea........... and we're still on jackstands 😁
It's a beast no doubt, with the H pipe it will sound deeper and more rhythmic. Uniting both sides in sequence. Either way love the sound

I worked at a shop when I was much, much younger and the two other mechanics and started feeling sick, like maybe there was a flu going around, and the symptoms got worse. Terrible headaches, dizziness, and I even puked a couple times. No one outside of work got sick, so it didn’t seem like a virus. I mentioned to a doctor that was a good customer what was going on and he said it sounded like carbon monoxide poisoning. Turned out the exhaust system in the main shop had a piece of the ducting come loose and the exhaust fumes from the cars we ran inside the shop was coming right back in. The leak was in my corner stall so I guess I got it worse. It took a good month after we all had blood test confirming we did have carbon monoxide poisoning before I started feeling better.
BTW, when I did state vehicle inspections, a tail pipe was described was exhaust piping that extends past the axle. Side pipes were illegal in my state unless they came that way from the factory.
@@TheCrazyMoparDude68 I appreciate your words and experience on the matter. The way it's set up right now is not safe for any extended periods of driving, which I don't really do. However, if that changes I will be sure to make whatever changes needed to keep myself safe. Thank you for taking the time to tell your story and give me that info.
I like both, tailpipes have a little cleaner sound to me
I like the dump more
There is a massive difference in sound when the car is on jackstands versus being on the ground, ESPECIALLY with dumps. I prefer the sound and look of dumps, but as I get older (50 now), tailpipes are becoming more appealing.
Turn the dumps to the side the are a lot more menacing plus it is louder since the sound can travel futher have a nova II with a built merc 454 headers to cherry bombs down the rockers when I crack the throttle people jump
I've got dumps on my 1971 455HO(for the moment). Sounds great, but the problem is on sandy places, it make a hell of dust clouds around and in the car ...
You can always go side exit just behind the rear tire. I had a 400 SBC with 3 inch exhaust and x-pipe exiting behind the tire on both sides and you get the best of both worlds. You can still hear it and no more fumes/and kicking dust up.
I got 3 inch exhaust all the way out. Tell pipes over the axle. It doesn’t sound any different then turn down at the axle.
sounds great either way. The tailpipes add some "rasp". You'd probably get a better tone with tailpipes bent up over the axle, then back.
I like open headers best. Maybe a 18 inch extension on it. Call it good.
Wow《☆》Nice patina👍🏾🍺🤳Sounds great both ways. Saving weight without exhaust pipes. I'd probably go for a full exhaust system with X pipe to see if it gains any performance. All the extra weight is near the rear axle & may help with traction✌🏼😎☯️
Dont think he will gain anything . If he did he wouldnt feel it
Like the sound of an H or no crossover at all...plus easier to drop the trans!
My foxbody has dumps and I love it sure I can smell the fumes and it’s loud as shit but that’s what makes it fun lol
Didn’t sound much different from the back of the car but probably easier on the ears inside. Old lady scare at 100%!
It’s not so much a change for the outside as a change when you’re in the car. Much better inside.
Dumps is better but you need to put an H pipe 14 inches back from the collector. This will provide a much better sound and pick up a couple of horsepower and torque. Trust me it will sound much better with the H pipe deeper tone of power.
Sounds good, I'll take the out the back choice.
The 57 is super ! Does it go Down the track ? If so what does it run ? On the exhaust I like over the axle because I have a half mile of gravel drive to get to pavement. Otherwise, we should have the sound that we like, to scare people with 😎
When I was a teen, my car had a leaking exhaust manifold gasket. That led to me discovering the the joys of carbon monoxide poisoning by once suffering from nausea and vomiting. I strongly suggest getting your exhaust into the airstream. Chronic low-level exposure can cause heart, lung, and brain damage.
73 f250 with a fe390 had a 90° bend behind the back tires after a couple years they rusted out now they dump behind the cab
My 427 sbf motor is sooooo loud with dumps... Vs tail pipes, especially at WOT. Lol❤❤
That engine is so rowdy that they "tailpipes" really didn't make much difference in the sound. Now the exhaust smell issue is another story. I was running headers/short mufflers and dumps that came to the middle of the door. Every time I drove the 55 I could smell the exhaust. I added 4' of pipe and it now the end is in front of the rear wheels. Still loud but no smell.
@@bigblockkings1031 Yeah I hear you, after doing this test I've decided im gonna move those turndowns back another foot or so, just so they aren't right directly under me.
I do like the dumps. Fender well headers on my 56 with turnouts all outside the frame.
@larrythompson7802 same here.
Tailpipes always make it louder
For a street car, full exhaust out the back. Runs better, makes more low and mid range power.
Street strip car cut offs. I've had more hot rods than I can count and full exhaust was always better.
I like dumps with turn downs but, the dust they kick up is annoying.
I think it’s louder and sounds better with the tailpipes, but sounds mean either way!!!
Haven't even watched the video yet, hand down turn downs sound 100 times better then tail pipes
See You At Pleasanton 11 What ever !!
Used to run turbos n turndowns for decades, love that sound!
If it werent for the laws id do it again today but dont wanna give them more reason to pull me over.
Tailpipes to rear, 45 dg turndown rear bumper.
With our latest stupid Ca noise laws. putting 22" case superturbos on, same tailpipes.
Maybe elec cutouts if I get the itch but prolly not. Thats another ticket. lol
Muffs are more about sound, not much to gain there.
Id move.... Can run open headers where I live.
Did that on my car and sounds great but has a Wicked low rpm vibration
I had it on mine too, It's cool. Seemed to rock the car back and forth more too at idle which was awesome.
Dumps.....just the price of being fucking cool
It's not all about sound, there are performance considerations, no? Doesn't the length of the exhaust affect the performance of the engine? Signal at carburetor?
I NEED that shifter ball! where can you find that at???
I custom make those myself.
side exit for the win lol
Personally, I HATE driving around with dumps. If it's a dedicated race car, that's one thing. But all of my street cars have tail pipes.
It all depends if there is significant drone inside the car. I had a 305 with a mild cam and heads and had the exhaust dumped at the axle and flowmaster 40 series mufflers with no crossover pipe and it was decent. Hardly any drone and it had a good sound.
@@ck4181 Had those on a number of cars since the mid 80s .
Drones way out of control, crossover or not didnt matter
Back then if you had a stock engine and loud mufflers car guys would give you chit, yell poser at lights etc lol
Serious questions for you young man. 1. Do you think my 331 Sbc solid lift roller .575 with 1.5 roller rockers, 255/255 duration at .050, 110 LSA, 64cc aluminum Brodix 2.08/1.60 .700 lift springs/10 degree keepers, 5.5 cc dome etc. etc. etc. mouse could benefit/run well/not be a pain to drive on the street with 3.55 and a t56 speed, if I put on a dual quad setup like yours? Or should I stay with my old school Weiand 7508 single plane and circle track 650 Holley/no choke horn setup? I’m itching like a high schooler with crabs 🦀 to run a 2x4 setup. Low or high rise. Thoughts? Don’t care about rpm ranges, it sees ALL OF THEM! 😂 not worried about a loss of torque or hp here or there, just want to know if I can still drive it 5 days a week if I so chose to terrify all who dare to leave their homes without checking with me first. 😊 thank you kindly in advance for your 57 driving, balls worthy advice. Also 2. Did you do the dirty rag aluminum to magnesium wheel conversion? The wheels look like I went back to the 60’s at a gasser event in my not for rent/sale Time Machine. My favorite TH-cam car!
@@grendel.6.531 1. You can definitely drive with dual quads on the street, but it will take some time and work to get it dialed in right. If you're a pretty savvy tuner you won't have too many problems. I can guarantee you will have bogs, flat spots, backfires etc. but if you know what to do to solve those issues, you'll be fine. The only other issue is cold starts, takes a while to even get mine to idle on its own, and it's popping and chugging if I start driving before it's warm.
2. The wheels on the car in these videos are real American Racing magnesium wheels, however, they do have some graphite spray treatment because the front wheels patina doesn't match the rears, so I use the graphite to darken them to look the same.
3. Thanks for the compliments and watching the vids, I appreciate it.
@@sneakypete129 thank you for sharing your experience! I can deal with some tuning to look 👀 cool like your car! Also, try adding a couple O2 sensors before the mufflers and a gauge will help you dial in the carbs/linkages if you’re experiencing some of those issues. Bad ass car man! I loved those Bullets on it!
There are two problems with " dumping " the exhaust out right after the mufflers , first off , everything behind the pipes gets covered in soot , as do you when you have to work on it . Second , and more importantly , after while the combination of exhaust heat and the moisture from the condensation , will rot out your floors faster . Iitt takes several years , but you will learn how badly you screwed up .
I never encountered that problem because I learned how to tune a carb (okay, before I learned to tune a carb…maybe… 😅) and, I also am a true hot rodder who likes to spend time with his babies and of course my German Shepherd (who will absolutely NOT EVER leave my side….or fail to lay right where I am working…) oh yeah, my babies (cars) washing them even if it’s to bring out the patina more. Not bashing you, just pointing out that if that carb ain’t right, what you said WILL happen eventually. You might have just helped a few people out by mentioning this. 🇺🇸👍
@@grendel.6.531 in case you are under the delusion that I know nothing about this little game called " run what ya brung " , my last engine before my vision problems set in , was a .060 over 427 BBC , with 12.5 to ones , open chamber World Products heads , and a GK split cam . 627 @ 332 intake , and 629 @ 340 exhaust . The vision problem , you want NO part of . It called ' detached retinas ' . The very condition that caused Garlits and Amato to quit running Top Fuel .
Could always reroute the exhaust to your purse. Bet that would tone it down.
PA, and I'm sure most states, says that the exhaust must be a sealed system exiting rearward of the passenger compartment.
Now that that's out of the way.... I'll share some knowledge from memory and I hope I remember it all correctly. From a performance / drivability standpoint, some mufflers want tail pipes. At least 18", sometimes longer. Some mufflers, like the typical "turbo" muffler don't care. I know Flowmasters like tailpipes. I forget what glasspacks like.
The issue is the pressure waves. The negative pressure wave that scavenges the exhaust starts at the first significant change in exhaust diameter. This is typically the muffler. This is where the "engines need backpressure" myth starts. People would remove the muffler and go straight pipes out the back and they significantly extended where the negative pulse starts. Flowmasters like tailpipes because they are tuned to scavenge the muffler, so the inlet is what the engine sees, but without a tailpipe the muffler backs up with pressure.
This is similar to the intake in that the longer the distance, the lower in the RPM band it likes. With most mufflers it's just the muffler placement that matters, the length of tailpipe doesn't. I was never into glasspacks overall, so I really can't remember but I think they're different than most in that they do not start the pulse at the muffler. So dumps are preferred.
I do see you have fender well headers with cutouts, but street performance and drivability are still a thing. Just keep it in mind that the type of muffler and tailpipe selection can have an affect. 30hp+ losses aren't uncommon for really messed up systems.
With that out of the way, tailpipes or dumps are going to affect the cabin noise mostly. Dumps under the car will cause it to drone inside. I was never a fan and only ran dumps on trucks. Cutouts are a different story... Dumps, or any under car exit will create more of a deep boomy sound and kill the burble. But, turning down at any point and bouncing the sound off the ground will kill the burble to some degree. Think of the old Camaro exhaust that exited right after the rear wheel and pointed mostly down, angled out. Take that same exhaust and turn it and run it out the back and it sounds very different.
How about, 45 degree out after the muffler, then turndown in front of the rear tire, still under the car? I like to point them an inch or two in front of the outside corner of the tire and "45 degree" is a suggestion - you may need more or less. The idea is to bounce the sound off the ground under the car but get the flow outside the car. It also looks really cool during burnouts.
At the end of the day it's your car, so do what you like. No matter what you do it's hard to argue with a tunnel rammed SBC in a 57 Chevy... Good looking car and that small block sounds wicked.
There's nothing here but a post of rambling
The burble you speak of is exactly what I don't want. Again, just personal preference. As for the performance aspect, we will get into that more in videos to come. Right now I'm primarily focused on the sound and experimenting with that. Lots of good info you provided though.
Tail pipes sound better. Either way, your rod is bad ass!
I have dumps with Magnaflow's and too much drone and too loud. I' gonna run full pipes out of the rear. Mild 327 motor in a 55 Chevy.
SICK SHIT !!!
Dumps are bad ass i didn't even hear it yet exist behind drive seat
Poor old ladies and children...
What brand of gauges are those under your dash? I need some to try and match up to my galaxie
@@sammyvices2547 Stewart Warner green lines. These are old ones but they still make them.
@@sneakypete129 thank you, I like your ride by the way the stance and wheels look proper
5.0 Mustang pushrod fuelie.
I went from turndowns to tail pipes and lost 15 hp instantly. 😳
I like to hear my engines too
Even with the dumps it doesn't sound that aggressive because it's got mufflers. Long tube headers with no mufflers would give it a REALLY aggressive sound. But why not include an X-pipe? All crossplane V8s scavenge better with an X-pipe, so they make more power and torque.
Tail pipes sound more aggressive
Nice
dumps rule !!!!
Dumps for the MF win! 👍
I have dumps & cutouts on my 71 Camaro and wouldn't have it any other way! F*ck "quiet". If someone wants quiet go buy an EV!
Do an H pipe before the mufflers will sound much better my opinion try it out bud.
I don't dump exhaust unless i need to. full pipes all the way
I'll tell you where it makes a BIG difference
chambered mufflers. they always sound better with tailpipes
definently dumps
I'll take them just passed the bumper
An x pipe would make that big girl sound awesome.
Yep
For a long time in Texas dumps were illegal. Not that anyone followed inspection laws. The law states exhaust must exit from under the vehicle.
And now it’s changed.
Now it says it must exit past the passenger compartment. That would make SUV’s and cars with dumps not legal, pickups I guess are ok.
It screams lazy and to loud cause the sound echos off the ground and back to the vehicle and just makes it louder inside the vehicle. And if you ever decide to take the girl or wife or significant other or kids with ears that have not been abused for 40 years it’s not good for them.
My 74 Camaro goes all the way to the back, I think the old muffler insulation is gone. It’s and old set of turbo mufflers. Yeah it’s loud.
The truck exits in front of passenger side rear wheel. It’s also loud. Almost to loud, at highway’s speed it’s loud, but sounds good.
I have never liked dumps, it just seems unfinished. And it gets exhaust all over everything under neath.
Dumps are just not cool. I just do not like them.
