My grandfather was foreman in a foundry and taught me how to use a torch. In the rust belt a torch is your best friend. I watched Rainman Ray do an exhaust the otherday using a cut off wheel. I found myself yelling fire up old Vic and chop it off already.
I also watched that Rainman Ray video on the Mustang exhaust, and after the 3rd or 4th cut-off wheel, I had the same feeling. Saying to the screen..."Just get a torch, like Eric O."
Living in Michigan and owning older cars, the efforts to keep up with rotted and broken exhausts have been -- well, exhaustive. No lift, no torch, just the joy of laying on your back grinding and sawing and swearing while the rust crumbles into your retinas.
The larger flange is there to add weight. This changes the resonance frequency to help control NVH inside the cabin. Some think it's to add rigidity to the flange, but I don't think so. Anything outside of the bolt spread would be useless for that. Using the torch (blue wrench) to remove the old exhaust is actually easier, safer, and faster than any other method. A grinding wheel is difficult to use in tight spaces. A reciprocating saw requires clearance for the blade and could cut through the body tunnel. It would also have tons of vibration, and will bind as the exhaust comes loose and moves, pinching the blade. Not to mention the noise. A torch also has the advantage of "It can't be stuck if it's liquid!".
I was wondering about the weight aspect of it. Ford has always had weights dangling off their exhaust systems. Way back into the early 90's they had weighted exhausts. Seems legit.
@@SouthMainAuto The large flange is sacrificial here in the Northeast. Think of it like zincs on the bottom of a salt water vessel😂. Just kidding folks
Or, the factory screwed up and instead of wasting them, they just welded them on. I doubt aftermarket mfrs. care about resonance over material cost when they could have added that mass somewhere else using cutoff/waste material.
I recently watch another TH-camr mechanic from another State do an exhaust on a Mustang. He used sawzall's and cut off wheels and seem to be struggling in my opinion. I kept thinkig, dude, don't you have a torch? I guess I'm old school and am retired, but when I turned wrenches for a living, the torch was my friend. Keep on Torching Eric O! Love your channel.
Mrs. O has a lot of patience with you. Watched a guy at a muffler shop cut exhaust off with a tool with roller cutters. He said some times he would torch them off cause the tool wouldn't fit the space, he didn't like getting burns from sparks and hot ends. The end result is what counts!
I'm with you, torch is king. The fact that your skill with it allows you to cut off nuts without damaging the stud threads should quell any concerns as to how precise the torch can be. Nice job, I'm off to my shop now.
A someone who has used a torch all my like (I'm 74) it is amazing how few people can wash a nut off bolt and still use the bolt. Great job Mr. O. Love your videos!!
Mr O, you always do the best you can with available parts, i wish all shops were like yours. That exhaust looks spot on :-D That cat is lovely, such a friendly little sole. ( i don't think it's just the food you give it )
That's something I don't miss after moving South. Haven't had to have any exhaust piece replaced in 25 years. Used to be every few years it seemed liked.
I'm in the UK, and I had a diesel Peugeot from new. After 15 years, the original exhaust needed replacing, so, as the rest of the car was still good (no serious rust problem here), I decided to spend a bit extra and fit a genuine factory system. 4 weeks later the car was rear ended at a red light and wrecked.
I'm from Estonia and had 13 year old diesel Xsara- it's downpipe broke off straight from turbo- had only that welded together- no problems from exhaust for a few years I drove it more. With OEM stuff I would rather repair just that broken bit- cheap aftermarket stuff "Walker" etc would be worse in a year than "temporarily" welded OEM stuff. Maybe it's not option in UK, but OEM exhaust parts (and body panels) are few things that should be taken from car wreckers.
Watched a old video of Ms Hanna changeing her front brakes on her Malibu an I must say you taught her well. She even did the thing with the brake cleaner perfectly. When you retire she can carry on your legacy Mr O.
Eric used his cutting torch day in, day out so I'm sure he knows what he's doing and is entirely comfortable with it. I only recently got the sheep reference with the Fluid Film and I used to work in the wool textile industry many moons ago. I'm sure Walker supplied Ford with OE exhausts at one time.
From a dealership automotive tech to an awesome shop tech/owner. Top notch diagnostic job ol son,and excellent job breaking it down for the viewers. 👍🏻
Never question a man who trained an outside cat how to sit and shake. He has way too much patience for you! I’m wondering if you could send that Walker exhaust out to be jet hot coated, maybe that would make them last a lot longer.
The best thing about SMA is the burning, the grinding, the smashing and the ole UGaduga sounds. Progress in action! All the best Eric. Love your comment about the hotdogs, garbage meat. Get the smoker going!!!!!
Good job, Eric! All tools are dangerous - it's up to the operator to use them safely. Many years ago, I was told "a tool is only as good as the person who uses it", and you know how to use a torch 🙂
Appreciate these really informative videos. I live in California. I have a 1995 Toyota P/U with 200K. The exhaust system is in perfect condition after almost 30 years. For those of us not in the rust belt this stuff always amazes people like myself...
@@mod_incllc3235 Mine also is a T100 SR5. Honestly, in 28 years it has never failed to start or run. These trucks were know for easily rusting. I doubt there are very many of these left in the rust belt...
The hardest part was taking the plastic off the muffler tips! As for the oxy/acetylene cutting torch the main concern (for me) would be those hot sparks. Saw one guy get a hot one fall in his shoe!
About the flange sizes: According to a Ford engineer, with the larger size primarily on the down-pressure side, their testing said it helps with creating a tight seal with the gasket and allows for tighter torque to be applied without deforming the flanges and prevents flex between them.
As a mechanical engineer, I have a hard time believing that anything larger than the area between the two bolts, or larger than the mating flange for that matter, is helping. Thicker flange? Sure. It will increase the rigidity. But to add more material outside the "clamped" area doesn't make sense to me. That being said, I'm sure Walker just matched OEM and didn't put an iota of thought into it lol.
My guess would be for NVH. The added mass likely used for changing or moving an exhaust mode resulting in less Vibration / drone. Cheaper than adding a tuned damper.
Good morning Eric, One of my female cats love hugs, so I taught her to put both front paws into my hand once she is on the arm of my recliner to get a hug. She snuggles in close and seems to want to stay forever. My other female gets up on an ottoman next to my chair and does a little mew, then leans over and lays her head down on the arm of my chair to get a hug. The youngest tucks me in bed every night by laying on one of my hands till I start to dose off, then moves down to my feet. I am allergic to cats, go figure, I have 5 of them. BTW, my cats only get treats if they come in for the night. They also don't get wet breakfast if they stay out all night.
2 hours down I86 we have a nice little exhaust shop in Busti, NY. Does custom stainless, very reasonable. Carlson's muffler and Brakes. Friendly. His opening line : " did you gou to jamestown high?" Year graduated? 1980- whips out the yearbook! Hahaha!
Eric I guess between your generation and mine we didn’t have all the battery tools so we learned to work with the tools we had, although in this area gas and oxygen have become very expensive but what hasn’t. KEEP UP THE GOOD WORK I ENJOY YOUR VIDEOS
Awww Luna. My wife had a Siamese mix before we got together. Misu looked derpy but I taught her at age 11 how to give a paw, then the 'other paw' for a treat. She was such a good girl. As far as the cutting torch, if you know how to use it, it's the best time saver.
AP and Walker. Back in the 60's and 70's, those were the systems my Dad installed at his shop in Franklin Massachusetts. And like you, those systems didn't last more than 2 years. Salt and sand corroded out the car (before aluminumized exhaust systems and body parts), so maybe 6 to 8 years with a car or truck and time for a new vehicle. Good one Mr. O. Nice to see Mrs. O and of course your dependant..the cat.
The gas axe is the tool wee need to see from time to time on your channel Eric! Who doesn't like a naked flame & spark flying every where. Plus the occasional "You Mother Lover" as a piece of molten metal makes gentle contact with your skin is part of the entertainment! Keep cutting with whatever tool you see suitable for the task at hand 👍.
I grew up working on cars in Michigan ,so yeah know all about the rust. I moved to Georgia over 20 years ago & my 15 year old vehicle still has the original exhaust. That's one thing nice about southern vehicles. You will never need a new exhaust unless you're changing the sound because its not going to rust that's for sure. Enjoyed the vid
As being an old retired mechanic working for flat rate you learn the "Old Victor" is a real time saver. One thing I have noticed is when you are using the cutting torch you tend to have a carburizing/reducing flame, is that by design?
Erik a HUGH difference between having the knowledge and skill to use a torch and sitting in front of your computer telling some one how to use a torch. Learned torch use at 12 years old, and have not yet burned down anything that I did not intend to burn, over 60 years with a torch!
Eric and Vanessa Obro! YOU ARE MISSING IT! You have built a brand and need to CA$H in on your merch using Erics sayings! Tee with "Enhance, Enhance!", also " Theres your problem Lady", then theres "HEY! Its that guy!" Not sure how to do a Brakekleen tee but theres a way, "Lawn Mower Man across the street". These things could go viral! Special editions and signed versions.
I use a torch but I gotta say a machinist I knew he was a old timer and made a lot of heavy logging equipment in his stop. He made his own tools lathes and crap . Anyway when the big drive line shop was charging $400+ to build a drive shaft he charged $35+ parts . I did a lot of custom stuff and he made me a pile of drivelines and I never had a comeback for a driveshaft. Anyway one day I went to his shop and seen him tearing out of his shops driveway in a station wagon hauling ass down the road leaving a trail of fire behind him . He drove 3/4 mile to the fire station where they put out the flames no harm . He drove back to his shop leaving a small trail of gasoline. He was doing a weld on trailer hitch on someone's car and touched his rod to the gas tank and blew a hole in it as the gas trickle out it ignited probably on the weld he didn't want to chance losing a fire with the shop extinguisher. So he drove to the professionals. He was about 1000 years old when I met him . He just couldn't stop working.
I think the torch is more precise/easier to handle and will fit into tighter spaces... Sawzall you always need the extra space for the moving blade and it can be kinda jerky and bouncy, a cut off is difficult to use in a lot of angles and spaces.
@@markh.6687 A jigsaw is too bulky to work in the tight space, You can get a full variety of type and length of blades for the Sawzall, like anything pick the correct tool makes the job go easier. The problem is good blades are not cheap don’t last if used wrong. A torch will last a long time be safe and get the job done quickly in the right hands.
@@wirefeed3419 Certainly the jigsaw won't work for every job, just as a torch won't. And yes, those Sawzall blades get pricey; I burned through several cutting old drywall with plaster on it; never knew that ate the blades up like that, so had to get some higher-end ones made of Unobtainium or whatever until deciding to just sledgehammer the drywall down and be done with it.
The exhaust A+ , the hot dogs OMG ! Put them in a bowl or dish cover them with a bowl or dish , microwave 1 . 5 minutes , put them on a freihofers bun slit them down the middle add mustard in the the slit microwave for 8 to 10 seconds and enjoy . Simply the best !
I want to approve of Mrs. O's cooking with cast iron cookware. I use an enameled cast iron dutch oven for cooking omelets and find it gets my omelets done quite well. Cleaning enameled cast iron is easy. You are a great family guy. Your videos are essential viewing for me. That is a good exhaust pipe replacement, too. I am learning how it is done from you.
I don’t use an oxy-acetylene torch because I don’t have one. I get the job done with either a cutoff wheel on the grinder or some other cutting method. Not nearly as fast as the torch but as a DIY-er I don’t need to be profitable. Thanks SMA for showing us how to get ‘er done, and all of your excellent videos. I’m a much better mechanic thanks to you!
Good job 👍 Where the aluminium heat shield meets the steel studs and nuts, it will always get eaten away because they are “dissimilar metals” and this causes “galvanic corrosion” That back box has a shocking junction with the centre pipe. We have Walker Exhausts here in the UK and they are low grade here as well 😂 Excellent vid as ever 👍
Maybe that large flange is a damper to reduce NVH. My dad had a 1989 Grand Marquis and where the front downpipes met the intermediate pipe there was a 2" diameter by 3" long steel weight bolted on with the flange bolts.
Long ago I worked at a tire shop that also did about anything under a car. We used the torch on exhaust and to cut the nuts on the single nut end of shocks.
When I was in college, '70s, I stripped military jeeps for parts for the rural fire program in kansas. I learned real quick which bolts never came out so I just torched them off. I never set any of them on fire
Hmmm... re exhausts rotting away this quickly: Would it help to cover the exhaust with high-temperature resistant color (like the one you use to paint ovens and some such)? Just a thought... Thanks for another entertaining and instructional video of yours! Oh - quite impressing how you trained your cat! Can I send in our dog for some additional training? 😄
Exhausts also rust from the inside, due to water vapor and condensation from combustion, so the painting might not buy much time. That, and Walker apparently using metal-coated thin cardboard nowadays. Used to be a respected brand.
@@markh.6687 Ahhhh... silly me - didn't think about condensation... well, if Walker and others would use decent steel plus perhaps the coating, that would probably give a more decent life span..?.. It's a pity that the flood of China crap inundating us all has pushed prices down so much that good quality is considered 'expensive' now a days...
@@charlesschneiter The typical American CEO's gotta earn those huge bonuses somehow, so they destroyed quality along the way. The more junk they sell, the more junk parts they sell to repair it; the accountants approved it. Everything is by the lowest bidder to the lowest quality standards that will make it through the warranty period (if that; sometimes they barely make it off the dealer's lot!).
A friend of a friend of my 2nd cousin on my mom's side told me the reason for the oversized flange is that the same exhaust pipe is used on the APU for the M1 tank. And I'm sticking to it. Thanks, Eric!
You really should get a plasma cutter Eric. It's just like a little welder that you tie in your air hose to, and as it's striking an arc -- your air blows it away like the torch does. It would pay for itself 5x over just by the amount of gas you save by not using your torch as much.. You can usually find them used for well under 200. Totally worth having in the shop.
@@beast36001 That "junk" will cut just as good as the torch up to a certain size. It doesn't sling any more sparks than the torch. The torch will still be used for a lot of things -- heating up bolts etc. etc.. But you can get away with using a plasma cutter on most of your simple cutting and not waste gas. Also you can take any little handheld sheet metal shield and direct the sparks any direction you like-- it' not an issue. If you've never used one and don't know what you're talking about, then you should probably not give advice about it.
I've got a 2008 Town and Country that I've owned for 8 years and never had a leak in the exhaust system. I'm in Alberta Canada, a windshield won't last 6 months before you've got a crack but the body of cars last a long time. No salt on the roads in the winter just sand and the odd small rocks mixed in. Side note we have a Luna in our family but she is a dog. Keep up the great videos, I watch them regularly.
It's a mix of 3 percent salt and 97 percent fine gravel when temperatures are minus 10c or lower. Which would probably be most of our winter. Not enough to rust out my van.
Eric, my guess is that the flange on the resonator is a larger size to help dissipate the heat during operation. I enjoyed seeing your trained kitty in this video. I didn't realized a cat would do dog tricks as well.
Eric I could watch you cut stuff all day with the torch, no idea why people have issues with it I like the fire and flames and smoke. I think the exhaust flange was a buy 1 get 1 for free offer available in one size only. And also nice to see Mrs.O taking good care of her man as she always does. Keep Safe Keep Strong 🦘🦘🦘🦘💖💖💖💖
I was laughing when you were talking about using a cutting torch. I’m not a mechanic, but my dad was for 40 years, and he used a torch on cars so often, it never crossed my mind when I see you use one in your videos. It’s like questioning why you use an air impact drill… it’s just a tool a mechanic uses, and not just in the US. Peter from northern Canada
Fire can be your friend or enemy. However, any tool in the wrong hand can be your enemy. I've used a torch since I was 15. That's somewhere in the neighborhood of 60 years. Torch is much faster and easier to use, I think. I sti;; like an oxy welder to. Great videos sir. Keep em coming.
I started in the mid 70's as a line mechanic. No mig or tig back then in any shop I ever worked at, but they always had oxy-acetylene. So, you grabbed the gas hatchet, changed the head to a #2 welding tip, grabbed a welding rod, and welded up the exhaust. Sometimes we used coat hangers if we were out of rod. It was no big deal as long as you were careful about not setting the carpet on fire inside the car. :)
I think I mentioned this before but this is bringing back incredible memories of me laying on my back in the snow under my 1965 Ford van and using a green bean can to do the hookup now I can't even sit too low I'm afraid I can't get up
When I was a kid, there was a shop / gas station at the bottom of the hill which my neighborhood was on. The guy that worked there for years used his torch on everything. So much so that he always had his cutting glasses on his head and one of what I guess was a cutting or welding cap. Watching from rusty Nova Scotia. I thought every shop everywhere used a cutting torch. Oh yeah and nice job Mr. O
Mr O., I have watched quite a few of your videos and have massive respect for you and I learn so much from you, as I'm a non professional who just tries to do what I can myself. But, lol, I'm calling you out on this one. How dare you have a complaint to the poor and tolerant Mrs. O. About those perfectly cooked dogs? My wife would tell me buy 'em yourself and cook 'em yourself. You don't know how lucky you are.
I've seen lots of impressive things on this channel. but getting a cat to sit and shake for a treat may have just taken the cake😀

Eric I guess between your generation and mine we didn’t have all the battery tools so we learned to work with the tools we had, although in this area gas and oxygen have become very expensive but what hasn’t. KEEP UP THE GOOD WORK I ENJOY YOUR VIDEOS
Yeah exactly, it's not like sawzall blades or cutoff wheel discs have gotten cheaper lately.
Awww Luna. My wife had a Siamese mix before we got together. Misu looked derpy but I taught her at age 11 how to give a paw, then the 'other paw' for a treat. She was such a good girl.
As far as the cutting torch, if you know how to use it, it's the best time saver.
Luna is the ONLY cat that I know of that sits and shakes on command...cute
AP and Walker. Back in the 60's and 70's, those were the systems my Dad installed at his shop in Franklin Massachusetts. And like you, those systems didn't last more than 2 years. Salt and sand corroded out the car (before aluminumized exhaust systems and body parts), so maybe 6 to 8 years with a car or truck and time for a new vehicle.
Good one Mr. O. Nice to see Mrs. O and of course your dependant..the cat.
You always make fixes look so easy 😂
With almost a Million Subscribers i wouldn't change a single thing! Keep doing what Your doing my friend!🙏🏻👍
The gas axe is the tool wee need to see from time to time on your channel Eric! Who doesn't like a naked flame & spark flying every where. Plus the occasional "You Mother Lover" as a piece of molten metal makes gentle contact with your skin is part of the entertainment! Keep cutting with whatever tool you see suitable for the task at hand 👍.
I grew up working on cars in Michigan ,so yeah know all about the rust. I moved to Georgia over 20 years ago & my 15 year old vehicle still has the original exhaust. That's one thing nice about southern vehicles. You will never need a new exhaust unless you're changing the sound because its not going to rust that's for sure. Enjoyed the vid
As being an old retired mechanic working for flat rate you learn the "Old Victor" is a real time saver. One thing I have noticed is when you are using the cutting torch you tend to have a carburizing/reducing flame, is that by design?
Erik a HUGH difference between having the knowledge and skill to use a torch and sitting in front of your computer telling some one how to use a torch. Learned torch use at 12 years old, and have not yet burned down anything that I did not intend to burn, over 60 years with a torch!
😄 This video is the definition of "Not my first rodeo". Watch, listen, learn. 👍👏😉
Eric and Vanessa Obro! YOU ARE MISSING IT! You have built a brand and need to CA$H in on your merch using Erics sayings! Tee with "Enhance, Enhance!", also " Theres your problem Lady", then theres "HEY! Its that guy!" Not sure how to do a Brakekleen tee but theres a way, "Lawn Mower Man across the street". These things could go viral! Special editions and signed versions.
I use a torch but I gotta say a machinist I knew he was a old timer and made a lot of heavy logging equipment in his stop. He made his own tools lathes and crap . Anyway when the big drive line shop was charging $400+ to build a drive shaft he charged $35+ parts . I did a lot of custom stuff and he made me a pile of drivelines and I never had a comeback for a driveshaft. Anyway one day I went to his shop and seen him tearing out of his shops driveway in a station wagon hauling ass down the road leaving a trail of fire behind him . He drove 3/4 mile to the fire station where they put out the flames no harm . He drove back to his shop leaving a small trail of gasoline. He was doing a weld on trailer hitch on someone's car and touched his rod to the gas tank and blew a hole in it as the gas trickle out it ignited probably on the weld he didn't want to chance losing a fire with the shop extinguisher. So he drove to the professionals. He was about 1000 years old when I met him . He just couldn't stop working.
I think the torch is more precise/easier to handle and will fit into tighter spaces... Sawzall you always need the extra space for the moving blade and it can be kinda jerky and bouncy, a cut off is difficult to use in a lot of angles and spaces.
Don't forget using a jigsaw in a pinch with a metal-cutting blade. It has a shorter blade stroke.
@@markh.6687 A jigsaw is too bulky to work in the tight space, You can get a full variety of type and length of blades for the Sawzall, like anything pick the correct tool makes the job go easier. The problem is good blades are not cheap don’t last if used wrong. A torch will last a long time be safe and get the job done quickly in the right hands.
@@wirefeed3419 Certainly the jigsaw won't work for every job, just as a torch won't. And yes, those Sawzall blades get pricey; I burned through several cutting old drywall with plaster on it; never knew that ate the blades up like that, so had to get some higher-end ones made of Unobtainium or whatever until deciding to just sledgehammer the drywall down and be done with it.
Mrs. O is sure a good sport for putting up with you Eric!!
Another job well done. Good work Eric. 😎
The exhaust A+ , the hot dogs OMG ! Put them in a bowl or dish cover them with a bowl or dish , microwave 1 . 5 minutes , put them on a freihofers bun slit them down the middle add mustard in the the slit microwave for 8 to 10 seconds and enjoy . Simply the best !
The big flange might be for a variety of cars, not just that one.
I want to approve of Mrs. O's cooking with cast iron cookware. I use an enameled cast iron dutch oven for cooking omelets and find it gets my omelets done quite well. Cleaning enameled cast iron is easy. You are a great family guy. Your videos are essential viewing for me. That is a good exhaust pipe replacement, too. I am learning how it is done from you.
Love your work Mr O. Thanks for all your hard work.
I don’t use an oxy-acetylene torch because I don’t have one. I get the job done with either a cutoff wheel on the grinder or some other cutting method. Not nearly as fast as the torch but as a DIY-er I don’t need to be profitable. Thanks SMA for showing us how to get ‘er done, and all of your excellent videos. I’m a much better mechanic thanks to you!
Good job 👍
Where the aluminium heat shield meets the steel studs and nuts, it will always get eaten away because they are “dissimilar metals” and this causes “galvanic corrosion”
That back box has a shocking junction with the centre pipe. We have Walker Exhausts here in the UK and they are low grade here as well 😂
Excellent vid as ever 👍
Maybe that large flange is a damper to reduce NVH. My dad had a 1989 Grand Marquis and where the front downpipes met the intermediate pipe there was a 2" diameter by 3" long steel weight bolted on with the flange bolts.
My guess is that the flange is used on many different exhaust systems, so they use one size blank for it
That was my thought, too.
Long ago I worked at a tire shop that also did about anything under a car. We used the torch on exhaust and to cut the nuts on the single nut end of shocks.
Let’s be honest, a torch is just more fun because there’s fire. Any excuse to use fire, we will use it.
When I was in college, '70s, I stripped military jeeps for parts for the rural fire program in kansas. I learned real quick which bolts never came out so I just torched them off. I never set any of them on fire
Hmmm... re exhausts rotting away this quickly: Would it help to cover the exhaust with high-temperature resistant color (like the one you use to paint ovens and some such)?
Just a thought... Thanks for another entertaining and instructional video of yours! Oh - quite impressing how you trained your cat! Can I send in our dog for some additional training? 😄
What would work better would be the makers using a better quality and gauge of steel.
Exhausts also rust from the inside, due to water vapor and condensation from combustion, so the painting might not buy much time. That, and Walker apparently using metal-coated thin cardboard nowadays. Used to be a respected brand.
@@markh.6687 Ahhhh... silly me - didn't think about condensation... well, if Walker and others would use decent steel plus perhaps the coating, that would probably give a more decent life span..?..
It's a pity that the flood of China crap inundating us all has pushed prices down so much that good quality is considered 'expensive' now a days...
@@charlesschneiter The typical American CEO's gotta earn those huge bonuses somehow, so they destroyed quality along the way. The more junk they sell, the more junk parts they sell to repair it; the accountants approved it. Everything is by the lowest bidder to the lowest quality standards that will make it through the warranty period (if that; sometimes they barely make it off the dealer's lot!).
A friend of a friend of my 2nd cousin on my mom's side told me the reason for the oversized flange is that the same exhaust pipe is used on the APU for the M1 tank. And I'm sticking to it. Thanks, Eric!
You really should get a plasma cutter Eric. It's just like a little welder that you tie in your air hose to, and as it's striking an arc -- your air blows it away like the torch does. It would pay for itself 5x over just by the amount of gas you save by not using your torch as much.. You can usually find them used for well under 200. Totally worth having in the shop.
bad move too much sparks, are u drunk? air moving the sparks all over, 200? lol you get junk for that
@@beast36001 That "junk" will cut just as good as the torch up to a certain size. It doesn't sling any more sparks than the torch. The torch will still be used for a lot of things -- heating up bolts etc. etc.. But you can get away with using a plasma cutter on most of your simple cutting and not waste gas. Also you can take any little handheld sheet metal shield and direct the sparks any direction you like-- it' not an issue. If you've never used one and don't know what you're talking about, then you should probably not give advice about it.
I've got a 2008 Town and Country that I've owned for 8 years and never had a leak in the exhaust system. I'm in Alberta Canada, a windshield won't last 6 months before you've got a crack but the body of cars last a long time. No salt on the roads in the winter just sand and the odd small rocks mixed in. Side note we have a Luna in our family but she is a dog. Keep up the great videos, I watch them regularly.
They actually do use salt in Alberta
It's a mix of 3 percent salt and 97 percent fine gravel when temperatures are minus 10c or lower. Which would probably be most of our winter. Not enough to rust out my van.
I use a peice of aluminum as a heat shield washer to avoid growing the size of the whole. My aluminum of choice happens to be a cat food tin lid.
I was waiting for the after market junk comment Mr O didn't disappoint
Eric, my guess is that the flange on the resonator is a larger size to help dissipate the heat during operation. I enjoyed seeing your trained kitty in this video. I didn't realized a cat would do dog tricks as well.
I hope you Escape the torch drama. My shoulders get exhausted just watching overhead repair work!
The Walker rot right around where the hangers are welded on. In the PRNY. I put 3 whole cat back exhaust on a 2000 Camry. Thanks for the video Mr. O!
Eric I could watch you cut stuff all day with the torch, no idea why people have issues with it I like the fire and flames and smoke. I think the exhaust flange was a buy 1 get 1 for free offer available in one size only. And also nice to see Mrs.O taking good care of her man as she always does.
Keep Safe Keep Strong 🦘🦘🦘🦘💖💖💖💖
I was laughing when you were talking about using a cutting torch. I’m not a mechanic, but my dad was for 40 years, and he used a torch on cars so often, it never crossed my mind when I see you use one in your videos. It’s like questioning why you use an air impact drill… it’s just a tool a mechanic uses, and not just in the US. Peter from northern Canada
12:20 those are the clamps Rainman Ray says are superior.
Mrs O is a good sport. Enjoyed the exhaust job.
Looks good. From experience those exhausts last about 2 winters here in NJ lol
The only thing I don't like about a gas axe is I don't have one & can't afford one Cheers Mr & Mrs O. Thanks for the video.
Fire can be your friend or enemy. However, any tool in the wrong hand can be your enemy. I've used a torch since I was 15. That's somewhere in the neighborhood of 60 years. Torch is much faster and easier to use, I think. I sti;; like an oxy welder to. Great videos sir. Keep em coming.
I started in the mid 70's as a line mechanic. No mig or tig back then in any shop I ever worked at, but they always had oxy-acetylene. So, you grabbed the gas hatchet, changed the head to a #2 welding tip, grabbed a welding rod, and welded up the exhaust. Sometimes we used coat hangers if we were out of rod. It was no big deal as long as you were careful about not setting the carpet on fire inside the car. :)
Not just north eastern thing. Knowledge confidence brother is a must.
I think I mentioned this before but this is bringing back incredible memories of me laying on my back in the snow under my 1965 Ford van and using a green bean can to do the hookup now I can't even sit too low I'm afraid I can't get up
Is that meat sauce from way upstate New York and it's called believe it or not Michigan sauce??
Enjoyed the video as always, I like my sausage dogs done on the grill with fried green peppers and onions on a hoagie bun.
Like chilli dogs too!!
When I was a kid, there was a shop / gas station at the bottom of the hill which my neighborhood was on. The guy that worked there for years used his torch on everything. So much so that he always had his cutting glasses on his head and one of what I guess was a cutting or welding cap. Watching from rusty Nova Scotia. I thought every shop everywhere used a cutting torch. Oh yeah and nice job Mr. O
Great video. Extra credit for some Luna action. Thanks. Good kitty
Mr O., I have watched quite a few of your videos and have massive respect for you and I learn so much from you, as I'm a non professional who just tries to do what I can myself. But, lol, I'm calling you out on this one. How dare you have a complaint to the poor and tolerant Mrs. O. About those perfectly cooked dogs? My wife would tell me buy 'em yourself and cook 'em yourself. You don't know how lucky you are.
It goes without sayin "everybody has an opinion" but the end result is what matters. Stay strong stop reading the negative comments
Opinions are like arseholes, everybody's got one
