- Glasspacks Vs Flowmaster- Which one do you prefer #glasspacks #holleyIn this video I compare the difference in sound of my previous exhaust to my current set up. The car is a 1956 Belair with a 327 SBC and a 3 speed automatic transmission. The previous exhaust system was long tube headers with 2 1/4" pipe into generic Glasspack mufflers. They exited out the back with chrome pencil tips under the rear bumper. The current set up is Corvette style cast exhaust manifolds into 2 1/2" pipe. It has two Flowmaster 40 series Delta mufflers with no crossover pipe. The tail pipes are tucked up under the corner of the bumpers so that they are not seen. In the Glasspack clips it had a Carter 600 cfm carb and in the Flowmaster clips it has a Holley Sniper.
Below is the link to the Flowmaster 40 Delta mufflers.

One of the best comparison vids I've ever seen sir!! Those flowmasters do sound good, different than most.. but those glasspacks take me down memory lane
Thank you Kirby:)
@@BigRed_1980 how long are the glass packs that you were running
@@ogphil5600 I did not measure them but about 20" long.
@@BigRed_1980 PURE aural sex!
Is this something that would get me pulled over constantly?
When it comes down to it, it's a personal choice. They both sound great, but I'm old school. My first car was a '62 Impala with a 327. I put glass packs on it and I loved it. Whenever I hear glass packs, it brings back some good memeories.🙂
Memeories?
@George Hays oh well...I can't be perfect all the time.🙂

Flow masters sound good. But I like the Glas packs better a lot better!
The Glass Packs sound incredible.
Nothing like good Ole glass packs love em!
I prefer the sound of the glass packs
The best sound comparison vid I ever saw. Multiple scenarios and good quality sound. I like the Flow master sound better, always did. Nice car by they way, thanks for keeping it classic and not over modernizing as many chose to do.
Thank you 😊 we definitely tried to keep the car looking like it should but still be able to drive it without worrying about it breaking down.
The flow master's sound crisper and cleaner ,the exhaust note is on point and fits the look of the car also. Good choice .👍
I had a 56 Ford Fairlane Convertible with the 312 Thunderbird Engine, Dual Exhaust Glass Pack's... never quite captured that sound again... loved it.
I have Flowmaster on my 1977 Malibu --- 406 with large cam, 3 inch custom full exhaust. Damn , its a very sweet sound and get alot of compliments . I also went from long headers to shorty headers.
My car pulls really hard and tons of top end power.
Really liked you comparison , 40 yrs ago we ran either gas packs, " Turbo mufflers" or the Hemi mufflers.
Technology in exhausts have given us alot of choices.
FYI, your '56 is very Kool.
Glasspacks all the way!
When I was a teenager I had a 66 Plymouth Satellite 361 ci ,3 speed auto .
I installed Hooker headers ,with Thrush header mufflers running all the way pass the bumper .
At normal driving it wasn't to loud ,but at full throttle,
Well let's just say, I got 3 tickets for loud pipes.
And one cop said he was a mile down the road when he heard me.
😄
Had that happen before when I had Thrush glasspacks on my Camaro, the cop told me he heard me coming a mile away 😆
I like the Dynomax mufflers myself. glass packs have a sharpness and the flow masters are easier to live with. nice video.
Me too. I have the Thrush 2 chamber welded mufflers (owned by Walker, like Dynomax) on my 71 Camaro. They came out shortly after Flowmaster lost their patent. Somehow they actually don't sound anything like Flowmaster. Maybe the baffles are positioned differently. Now Flowmaster has the FX series as their bargain line.
For close to 20 years, i fabricated Lobak Mufflers, and they were custom made in different sizes for different applications. They were track mufflers on a lot of stock cars and for dirt track cars, and we even made them to as side pipes on cobra cars as well as inserts in boat headers. Flowmaster wouldnt test against them in the early years, and flowmaster had a problem of the ends breaking off. The patent ran out on them and now a few companies make copies.
Good comparison video. I subscribed. Here is a simple tip I use for the battery tender, I drape something, like a towel, over the steering wheel anytime I connect the battery tender. That way it reminds me the tender is connected when I get in the car. I hope you post more content about the car.
I'm a pilot. I'm used to a preflight walk around. 🙄
My personal preference is always been glass packs, they always gave a nice smooth sound not over aggressive when you get on it just a nice clean old school sound
I put Flowmasters on my '70 BB Chevelle, and added a cross flow pipe. Outstanding sound!
I gotta go with the glasspack! Old school sound suits the Belair. NGL the Flowmaster sounds great too!
Yup, I think I'll take one Flowmaster off on one side of one of my cars and leave the other and replace the one I took off with a glass pack, that should sound pretty cool!! Just Kiddddding!! LOL :D
The glass packs have that classic crispy krackle. The Flows sound more responsive,solid, and tuned. Both sound good!
Best sounding exhaust system i ever had was my 57' chevy 283 with rams horn manifolds, dual 2 1/2 " pipe and Andretti turbo mufflers. Healthy sound with no annoying drone at cruise , but when you opened it up it was a whole different WILD animal. Loved cherry bombs but they always blew out quick, losing that awesome first day tone.
I"ve seen some old ads where Andretti endorsed flowmeters, I wonder if they are similar. As a kid I always equated Andretti with the indy 500, but later learned his was a regular race car superman.
@@richardelliott8352 actually, Andretti turbos were more like the high flow mufflers used on 69 roadrunners and other stock hi- performance cars, with a 26" case give or take unlike the 14" case more common now. A little more restrictive but still that classic muscle car sound. Walker turbos are the closest i could find ( 26" case)
Flowmasters for the win, they made my 318 Dodge sound and run great. Can't beat them. That 56 Chevy is sweet.
The glass pack are for hot boys, 40s are for grown men... 😂😂
nah the 40's are actually for guys that think they impress people with louder exhaust and think it makes their cars better than those without loud exhausts.
@chrisfaub4071 😂
The Flowmasters sound cleaner, but the glass packs sound more throaty. I'd rock either one. Beautiful ride btw. I'm hoping I can get a 55 chevy in the next few years. Great vid
I've ran Flowmasters before but never liked the "tinny" sound of chambered mufflers...love the "rasp" of glasspacks or any straight through "packed" muffler...Ole Skool all the way
I now want a barn.
Glass packs are great if they're installed right. Most don't install them correctly. I've always used a 30" glasspack/2- 1 for each cylinder bank. NO crossover & or H pipe before or after glasspacks. I've always put then in the middle of the car. Run 2&1/2" pipe back & over the rear axial & up around the sides of fuel tank & straight out to just past the rear bumper. Great sound & the fumes are out of the way. Plus, the sound goes out the back instead of in the car.
Definitely like the vintage sound of the glass packs.
Once those glass packs get used awhile, they'll sound even better 😮
I think glass packs sound like the less expensive option. Flow masters always have that muscle car sound while glass packs have that hot rod sound. So it depends on what you are building to Mach the sound IMO
They both sound great to me. I like the glass packs because I'm a bit older and remember them well. Also like the Flowmasters because they're a little quieter with the edge off because I'm a bit older.
When it comes to tri 5 Chevy, I love the 1956 Chevy because everything is in the right place. Most people prefer that beautiful 1957 but if it's not black I don't want it. I grew up as a teen around a 56 Nomad with custom paint and to me that was the coolest car on the planet. I'm thinking silver base or white but the rest of it was psychedelic colors with metal flakes in the paint and it was show car or magazine condition and I always thought that wasn't nutn on the planet as cool as that car was. That's why I fell in love with the 1956 Chevrolet and the dude that had it totalled it and I had a hard time getting over it lol...I kept it shined up and he got run into a rock wall and it wasn't even his fault but I's mad over the car cause I seen wrecks and people fixed em but he was rollin and it wore the car out. I never seen it anymore cause I asked him if I could have it if I go get it from the wrecker service that towed it and he's right and so lucky to have made it out alive. Rock walls are hard on even the heavy metal vehicles lol...Finally 1 day me and my brother went to look at it and the engine trans and the whole car was a total mess and it ran dam good for a small block engine putting out maybe 567hp cause I remember he took it to Virginia and dynoed it cause it was strong heavy and fast lol
Like your Chevy even though I'm a Ford guy. Used to run scavenger pipes which hung down under the car just before the exhaust pipes would normally go over the rear-end. I appreciate the nice comparisons.
Glass packs! 72 Chevelle worked 350, Accel dualpoint and coil. Love them CherryBombs! Was just a good fun combo. HEI and Turbo mufflers just didnt seem to cut the mustard on that car compared to the old school setup. It all depends.
I like the way both of them sound. I have an old Dodge Dakota with the 4.7 V8. I put glasspacks on it shortly after I bought it (new in 2000), but switched to 40 series Flowmasters after about a year. The Flowmasters sounded a lot better...but DAMN did those things drown out any conversation you hoped to have with the person in the back seat, lol. After those rotted out, I put 50 series Flowmasters on it and have had those ever since. It still sounds great from behind the truck, but the interior noise was greatly diminished.
they both sounded great but I prefer the glasspacks..The low growl is king...thanks nice comparrison...
A HS buddy had a dark blue '65 Malibu that had a steel pack muffler on 1 side & a "Hush Thrush" on the other.....made the most unique sound that I've not heard since. He also had a '65 sport sedan (1st year for 4dr. hardtop) Bel Air w/dual glasspacks...it was tutone India Ivory over Matador Red, redlines on chrome reverse.....G O R G E O U S !!!
Glass packs best by far.
They both sound good but I like the depth of the flow master tone. Awesome car!!
I like the way they came from The dealer, Nice and quiet
That was a fantastic comparison!! I can't decide! I appreciate both systems, my 77 ford tow truck has glass packs with a 390 sounds awesome and flow masters on my 460 f350 also awesome!!
tbh i would go headers and glasspacks, its what i just but on my c4 lt1, but they both sound so good
Man, the sound in your video is great! The car sounds great before and after i find.
Thank you😊
Definitely the Flow Masters! As my father describes them, "Muted but authorative."
My opinion as a guy who graduated high school in the early 90s....glass packs were considered the old fashioned "el-cheapo" budget muffler at that time.....flowmasters were the new and "high tech & state of the art" thing that the serious street race cars were running to get into the 10 to 12 sec et range....they sounded really exotic untill every 5.0 mustang on earth had them by the late 90s.
I still have a transverse 2.5" true dual exhaust flowmaster set up on my 75 455 trans am and love it..... although Im partial....to me a big bore long stroke RAIV cammed 455 pontiac will sound pretty mean with just about any muffler LOL! 😉👍
The only thing that helped me decide is I really want that car.
Flow master for the win, sound and install love the hidden exhaust.
I love the sound of long tube headers and glasspacks. But long tube headers are a pain. Those new and improved ramshorn cast headers seem to be the way to go. However as far as sound I would have to hear them both in person.
Btw SUPER NICE streatable hot rod car.
I like both. Changing to manifolds makes a big difference by itself, but it's still a good comparison. The glass pack and headers sounds more hot rod, the flow master and manifolds sounds more like a newer truck with a good exhaust on it. Hard to explain but newer vehicles (1998+) Chevy trucks just started to sound different. That's also because of the LS style heads. But I'll always say a SBC sounds better and I like your current setup! 👍
When I was young I wanted a loud blatty exhaust note and harmed my hearing out on the hiway. I have come to appreciate a quieter exhaust note, as long as she rumbles just a little and is hardly heard out on the hiway.
Glass packs by far is better. Install the mufflers as close as you can to the front giving you longer tail pipes gives you the best Cackle. Louder isn't always better, it's the tone of the rumble and cackle that makes that sweet sound.....
Well I do agree with the previous comments about old school and the classic glass packs but honestly on your particular application I like the Delta Flowmaster. I had a truck with the FM super 44s but on another one I went with 18 inch glass packs, couldn't get Flowmasters to sound good on that one
Beautiful Belair! i loved the flowmasters sounded nice. awesome video of comparisons! :D
I have fual turbo mufflers with a glasspack as a resonator on my 4L Aurora. I like the mellower sound, less "rappy".
Both sound good in their own distinct way. But I tend to like a deeper rumble with less rasp, so I’ll take the FMs.
Glass packs FTW! A nice little lumpy cam would
do wonders for that rig.
niice chevy. Had same dilemma had the FM then switched to GP SBV8 sounded deeper and meaner with the new cam
I've really never likes the sound of glass packs on any engine. Of course, it's a personal preference.
I think it comes down to personal preference. I have glass packs on a '56 Buick and I had turbo mufflers on a '64 Skylark as well as a '91 Chevy truck. They each sounded different but I liked them all.
yup, they are all good especially when you drive up and park next to a Prius, or Tesla, and "Rapp" them a bit to set off the car alarms!! Too much fun that!! ;D LOL
@@ronschlorff7089 Years ago my '56 Buick and I were the wedding car and driver for a good friend of mine. The bride wanted me to rap the pipes before we set off towards the reception. I of course obliged her and set off all the car alarms in the church parking lot and for quite a distance around the neighborhood. It was very amusing to say the least.
@@mikemullay5622 Yup, it never gets old. I used to drive through a three-level parking garage with my 67 Cyclone, 390, with not that rowdy of mufflers and pipes, but still managed to set off a lot of new car alarms!! LOL ;D
I do like the rumble that the flow masters give out not gonna lie but I do have to admit the glass packs do sound more aggressive n just have that right kinda tone to em
I have flow pro chambered mufflers on both my Vettes. They sound wonderful
Glass packs over dronemasters every day.
But everyone should pick what they like best, it's still a free country!
Flowmaster makes everything sound good
One hell of a nice barn.
I definitely like the sound of the glasspacks best.
I like the sound of both of them. It's all Masters sounded a little bit more aggressive. I got class packs on my 59 Thunderbird well I got Flowmaster on my 2010 Mustang I still like the sound of both of them
In my experience and depending on the gearing of your car, the flowmasters are great unless you are going to drive on the highway at all. The drone from mine would literally fatigue me.There were times I would cruise at 90mph just to get the RPM out of the drone zone. When I switched back to a glasspack the car was still as loud under acceleration, but it didn't have the loud oppressive drone at cruising speeds.
With the Delta muffler I don’t get any drone on the highway 😁
@@BigRed_1980
That's good. I did a round trip from Beale AFB to Houston and back and it made me switch to a Magnaflow glasspack setup. Haha
Glasspacks through tailpipes for the Win
Glass packs are the 60’s equivalent of the fart cans that the Honda kids all put on. In another 20 years we’ll all be nostalgic for that to. The glass packs are more ratrod and the flow masters are more muscle car. Piping size matters as well. The smaller tubes have more pop the bigger tubes are deeper. The headers vs manifolds matter too. Just 2 different styles
Like Fuzz Versus Distortion, it's a matter of taste and familiarity, and there are no wrong answers. And bottoming out sucks.
I had Flowmasters and headers on my old Chevy truck, but it was so loud I ended up putting glasspacks behind the Flows,
Mellowed it right out.
70 series Flow Master with an auger in each pipe infront of the muffler will make it quiet and still give performance.
Glass packs remind of of the sound of Tia Juana busses decades ago.
I've got dual Flowmaster 40 series mufflers on my LT1 Roadmaster. Love the sound. Even better since I added the x-pipe. It drones a bit, but I'm gonna try adding some glasspacks before or after the Flowmasters to tone it down a bit.
I've never heard of anyone removing headers to swap to manifolds but maybe there is something I don't know but Im gonna say glasspack all day sounds like she exhales real good
I HAVE USED BOTH ON MY 1961 SUNLINER. AT FIRST THE GLASSPACKS SOUND BETTER BUT AFTER AWHILE THE EXHAUST STARTS TO SOUND TINNY. THE FLOWMASTERS DO NOT SOUND AS GOOD AT FIRST BUT MONTHS LATER STILL SOUND THE SAME. POWER OUTPUT WAS NOT MUCH DIFFERANT BETWEEN THE 2
Its a great old school CHEV. The glass packs were the best, my opinion.
It may be because I'm a Boomer that I now prefer the toned down Flowmasters over the raspier sounding glasspacks.
Personal experience is that Flowmasters always sounded better with longtube headers, optional h-pipe
I like to take my 69 c 10 on road trips. At end of day I still like throaty sound…and no headache. Conversations are also easier to have. Just sayn.
On Chevy glass pack. On Ford flow master. Just my opinion.
Love the way the garage door opens. 😂
Great 56 !
Great comparison.
I wonder if it’s a generational thing ? I’m 55 Y/O.
I usually HATE the sound of Flow Masters. I took mine off my 70 Chevy truck 5 minutes after I got that truck home & put glass packs on it.
Yours are the best sounding flow masters I ever heard, but I still strongly prefer the packs.
Thank you. I did not install an x or H pipe and I think that is why they still sound raspy at the high RPM's :)
I'm 63 and have Flowmasters in my 56 for 16 years with headers, 327 ci and turbo 350 trans. Love the sound of my Flowmasters 😊
Luv those Glasspacks!
First of all, the ‘56 is my favorite of the Tri-fives. This car is gorgeous.
Thank you.
Excellent comparison!
Depends on the build for me I prefer flowmasters tho especially on a hot rod or something but something to cruise in glass packs aren’t bad
Like most everybody else.....I prefer the glasspacks.
Glasspacks ftw….i got 3” dual glasspacks about 16” after the collectors on my long tube headers and the exhaust exits right past the door openings on my nova before the rear tires…..its gotta LSA supercharged 370” lq9 in it, youd never know it was supercharged cause the exhaust is so loud you cannot hear the blower…..my c/10 on the other hand has 2.5” summit flowmaster knock offs and basically routed the same as my nova but instead it has a vortech centrifugal supercharged 5.3 in it and its definitely noticable ….the blower is way louder than the motor!!!…..im gonna put the dual 3” glasspacks on it soon too!!!
Fantastic video and fantastic car. BOTH sounded great on the car but I am leaning towards the glasspacks myself. Just a more classic old school sound to me. I'm putting a 350 4 bbl in my 57 this summer and I was looking for what kind of exhaust. I am also going with Ram's horns exhaust. Too many problems with headers over the years. So I say a big thanks for having this video. It helped me a lot. Love the car.
You’re welcome and thanks for watching.
They both sound good but call me strange, I like the glass packs a little better.
Sounds better with the glass packs for sure. I have always liked a muffler like the dyno max ultra flows. They are straight through like a cherry bomb style glass pack but much larger which cuts out some of the high frequencies and rasp for a deeper tone. I always thought glass packs were too raspy and flowmasters always sound hollow and cheap for some reason.
I like that deep throaty hot rod sound. GLASS PACKS All the way!!!!
K’know, I’ve seen a lot more BelAirs on the road lately around Clark County. Not really sure why, but I ain’t complaining.
Thanks for your time and for sharing..u about made me spill my coffee when you pulled out with tender hooked up..as if I've never done THAT. I'd be curious about the difference between the HEADERS and the MANIFOLD alone. That has to be a factor in the two setups.
I know that the headers flow more and most likely make the glasspacks a bit louder. It’s hard to say though as I cannot feel any performance difference between the two setups so it would lead me to believe the difference is minimal.
@@BigRed_1980 I believe in the "seat of the pants" is always better on a street car than anything else. I'm all about the FI but I love the old-school look. I liked your SUN gauge you had and I think your "field car" look good with chrome reverse wheels LOL. I'm changing up the exhaust on my car and I've been looking at some Flowmaster mufflers. And I like the MF #10416 mufflers. Your video has me curious about the 40 series Delta.
What a beautiful car! ❤
Thank you 😊
I’ve got the best of both worlds on my F250 with a 351w. 2 1/2” into a single 3” x 12” long resonator that goes into a Flowtech Raptor (flowmaster knockoff 1
Flow Masters are the way to go, sound so much better than the borla mufflers they putting on everything now just sounds like the cars are farting with boral sounds awful.
They both sound good.
Thanks 😊
I agree the glass packs sound a lot better....
Idling the Flowmasters but the take off and 35 to 60 ut Glasspacks
I tried to get a Flowmaster muffler for my RX4 years ago, and no one would se me one. Apparently they melt when matched to the Wankel.
