Fabricating Exhaust Parts -EricTheCarGuy
HTML-код
- Опубликовано: 26 июн 2014
- Fabricating exhaust parts is not something that you will always need to do but when you do need to, it's good to have the right tools and know how. In this video I fabricate the 'A' pipe on my 1993 Acura Vigor. The OE part is no longer available and if it was it would be VERY expensive. I could not find the part in the aftermarket either. That meant that I had to make my own pipe. Through a combination of cutting, grinding, heating, and welding, I was able to make it happen. It may not be pretty, but at least it's quiet. With a little more practice with my welder I think I'll have this. No matter what, I hope the information in this video can help you if you're confronted with a similar situation. If not, I hope you're entertained by the video as you watch me learn how to weld exhaust pipes.

Whether one agrees with his strategy or not, one of the huge benefits of his videos is in seeing his problem solving strategy. It's always helpful to see how someone else would solve a problem. I also like that things don't always go as planned, because that's real life. Great job, as always.
We get to watch his first try so our first try shouldn't have the same issues. 😄👍🏻
Eric, you are an inspiration to many people, and a man after my own heart regarding improvisation, and saving cash. You do a great job with clear illustrations which must encourage many diy's to have-a-go. I am 73 and have been an apprentice diy mechanic ever since I was 12, I am still learning. Keep up this great stuff you produce to help others who might be less well off. And yes! we do watch all these kind of video's here from within the UK with great interest.
Owen.
This man is very professional with all kinds of tools , speaking very good English, his career should be a TV star instead of a fabricator.
I know this is an old video and you probably won't see my comment, but dude, you're one honest hard working guy. Seriously. That is some fine fine work Eric. I'd be proud.
Interesting to watch for mechanic-dumbo's like me . Easy to follow, clear speech, unlike others on YT.
Ha, ha, Eric. That smug smile when you started it up was priceless!
So my '69 Dodge RamIt was making a lot of noise despite hammering my flexpipe in all night. Camera Man Bryan informed me that flexpipes are not kosher. Unable to offer a solution to please the entire audience, I offered these flange nuts as consolation. (I come for the articulate instruction. I stay for the innuendo. Never grow up Eric!
Thanks for showing the trick to remove the studs with the air hammer. As far as welding goes... I spent four months at our local college learning welding while I was dormant looking for a job I must say, you did well for not having training. Welding is an expertise in and of itself...... it is not easy. Keep your videos up and thank you for sharing all that you do.
Boys and their toys! Great video, Eric, especially watching you play with your welder and plasma cutter. I liked your mentioning how the one Acura exhaust part cost more than your paid for the car. That's a problem encountered by many of us. Seeing your work-around will no doubt inspire others to attempt devising work-arounds for their own problems.
That is my hope. Thanks for the comment.
EricTheCarGuy what's the name if or type of drill you used because I desperately need one :) and BTW I love your videos and they're super helpful :) #subbed
Eric, you are an outstanding instructor. I am so thankful for the helpful info. I now have confidence that I will get my exhaust repaired.
You ended up with a dirty shop, a fixed exhaust and a smile on your face. That's a win!
I got a little more practice with my welder and saved a bunch of money with this one. Fabricating Exhaust Parts -EricTheCarGuy
Try supporting the mig gun from the underneath of the welding gun with your left hand, probably need a bit more heat for the fillet weld on the outside, and you could just spot weld it cos its not supporting heaps of weight, just needs a seal really, but just keep practicing on scrap metal, use a push technique when welding instead of pulling it, gets more penetration, rough 30-45 degree angle is good
great job for a beginner. the welds look high, as in there is to much weld there. so 2 fixes faster travel speed ,or turn the wire speed down.
what heat and speed did you have it set?
Hey Eric just wanted to let you know i'm an instant subscriber, you are very well spoken and easy to listen to.
I first watched your video "how to remove a bolt with heat" or something, at a point (middle of the video or so) you start explaining how to light the torch and had an instant lesson on how to keep your cool when you get a leak, about "taking away the food for the flame." That to me is diy youtube gold.
Good job with these uploads and please dont ever stop, im addicted. :D
36 minutes?! I'm telling you. Make a 2:30 "digest" video and then the in depth version of each. You'll get more hits and revenue. I don't want to sit for over a half hour to watch something I probably will never do. but I'd spend 3 minutes watching it.
Jesus Ali Or develop an attention span
A pipe bender/expander is so helpful when you're doing a lot of exhaust work. Oxy-acetylene for heating or cutting rotten bits, a bender for modifying sticks of pipe, and a MIG when it all goes back together.
Rotten flanges can just get cut out and replaced with a sleeve...much easier than dicking around with rotten flanges and bolts.
thanks for this vid, exhausts don't look so scary to work on now, cheers
awesommeeee! watching you remove those rusty bolts was a joy in itself
Eric Thanks for all you do. I know that you take a lot of time to do this without a lot of money! You have inspired many including myself to at least try to DIY.
You know, I didn't understand the point of the vigor when you bought it, but it has led to some of your most interesting repair videos
Sawing, smashing, and grinding... that’s what working all of the cars I’ve ever owned is like haha
That was by far the most intelligent and logical way to tackle this, great job!
Eric!!!, you are amazing, show us step by step your task!!!
Thanks a lot!!!
For finding pinhole leaks. Hook your shop vacuum hose on the vacs discharge port and duct tape the hoses other end to the exhaust pipe end. Seal the far end of the exhaust with a stuffed rag. Turn vac on to slightly pressurize the exhaust internals and use soap or leak detector to locate the leaks.
Something very satisfying of doing a good job cheap for yourself .. enjoyed watching it matey.. cheers!!
You are a hero, no matter if you seald this up or not.
While I don't know nearly as much about the automotive side of this video (probably why I'm watching this channel rather than running one), as a metal fabricator I'm really surprised that you don't seem to use grinder cutoff disks much in your work. I use 1mm thick 5" cutoff wheels more than any other cutting tool, they cut quickly, accurately and work well on everything from sheet metal to pipe without any problems. They are also fairly portable and have a very low setup cost, since your going to need a grinder for most serous metal work anyway, even if the cost per meter cut is a little higher than some other methods.
Personally I'd have used these cutoff disks to remove the studs (where you used the oxy set) since this would be fast and not require as much grinding and have trimmed around the old three stud flange your not using anymore so you could put a external bead of weld on your new 2 stud flange. This is advantageous because as you say in the video the internal weld interferes with exhaust flow a little, but its also easier to get to the outside as well. If just to prove how much I stand by 1mm cutoff disks I'd have probably also used the grinder cutoff wheel to cut the exhaust hanger when you used the plasma cutter, this would have given a slightly less jagged edge and no slag to grind off.
Finally I'd have probably ground the worst of the welds and exhaust painted when I was done. This can seem like a waste of time, but it actually helps a job not only avoid rust and look professional, but the paint can help fill a tiny weld pinhole or two, a great help for those few "too small to really see" pinholes while learning.
On the other hand I'm horrified to hear that one pipe was going to cost >$400, it makes me realize how spoiled I have been parts cost wise for my jeep TJ. It also really runs home why more people should aim to gain the knowledge to work on their own vehicle. Especially since issues like these don't create large safety problems even if the repair isn't up to scratch, you can simply remove the pipe and try again, or if worst comes to worst, buy the replacement (or find one at a wreckers). So all in all still loving the videos, keep up the good work!
Man, angle grinders are so handy
I have to agree with your comments on using the thin cut-off wheels and cutting the old flange. I would have done the same. I would also have put a slightly baloney cut on the flex pipe before attaching the flange in order to reduce the bend on the flex pipe some, relieving the stress on it. Eric still got the job done and saved big bucks doing it so thumbs up to him.
I have a confession....
The first time I tried to repair a leaking flex pipe I was 17, broke and stupid... So I tried to use duct tape. Don't do that.
Jimmy Baggs
Don't feel bad, when I was young and stupid I tried taping my flex pipe too, but I went the electrical tape route.
Lol my brother once tried putting a sock in a muffler with JB weld so it would pass inspection, it blew out across the shop floor, should have seen the mechanics face . Hes an idiot still 40 years latter
I had a busted down pipe from the manifold, I patched it using about ten soda cans stacked with the ends cut off and cut down the side with two radiator hose clamps.
@@mobilechief ~ Classic comedy, buddy ! :-D
All of you are insane, the thing gets so hot that will melt anything you throw at it unless it is the right material.
Loved the way that plasma cutter does its job.
eric you're a hero for doing this without a ramp
I fabricated a full 3” stainless turbo back exhaust on the floor, my back is still suffering lol
@@Diesel8290 I'm about to be doing the same thing lmao
Did you see that happy happy smug smile when he turned the key at the end? hahah I love it!
I did a very similar repair on my Subaru outback. The aftermarket part to replace that section was around $300. With similar parts, the repair was about $20.
About anybody can replace parts now. There is very few repairmen out there now.
My hats off to you.
Gotta love cars from the rust belt. Window regulator goes bad? Fear not! Change it from the outside of what's left of the door. Brakes not slowing you down? Just Fred Flintstone it, no worries.
I jest... mostly. Great video, Eric.
This video was perfect, my girlfriend has the same problem with her hyundai elantra, will tackling this summer, thank Eric.
Did this same thing on my 2000 f-150. Like you, I was looking for an excuse to fire up my mig welder and see if my fab skills were up to the task. I was quite pleased with the results. That and the fact I didn't break any hardware :-). Good job man, good video!
Nice one Eric. Fixing exhaust this way sure saves a lot of money. Thanks.
This is a true video and the problem you can encounter when doing the exhaust good job Eric
Oooh, that was exhausting!
This is a splendid video, Eric! Thank you. I like your enthusiasm and your - I can figure this out and get this project done - outlook.
And the lesson for me is that I should make a trip to an auto parts store, pony up a few dollars and buy the gaskets I need ahead of time. I would want the pipes to have zero leaks. I'm just fussy that way.
A Happy Independence Day to you and everyone watching this video!
fnarr fnarr
Super tips, thanks Eric for great video - as usual :-).
Also thanks for Brian ;-) .
Awesome job as always,Eric.
probably one of the coolest and/or badass videos ever.
33:10 felt like I just turned on my car, watched this whole thing through. Awesome work!
this video is worth millions to me
Had that problem too with pinhole leaks in my welds. I just smeared them with furnace cement (exhaust cement) let it dry overnight. 100 % sealed in morning.
I do mock up when tacking welds to make sure it all fits like what your doing man nice work
Rusty exhaust is always a PITA especially if your up north . Thank you for another good repair video eric. This video got me remotivated to get after a hairline crack just after one of 3...lol yupp three cats on a 2000 dodge.
great tip if you want a temporary fix for a hole in an exhaust. Get a coke can cut the top and bottom off it the cut vertically down so you end up with a curved piece of sheet metal, wrap it round the hole tight then get two hose clamps and clamp each side. Costs barely anything and will last until you get it fixed
Nice job Eric, thanks for another great upload.
A very enlightening video. I've got a leak in my muffler. I just might try this with my Everlast welder.
you are both incredibly skilled and also lucky when it comes to at least one of those nuts on the manifold!
ingenuity at its best. Thanks
That was a great video, Eric well done.
awesome video Eric I have learned so much from you along the years
I just went through the same ordeal on my wife's uplander, bought an aftermarket muffler. (seam was leaking and starting to rot) I just cut the flange bolts off with an angle grinder removed the whole thing from the cat back, but I had to undue the panard bar to snake the exhaust through, over the rear axle, I wasn't expecting that. Then I measured from flange to flange and welded the old flanges to the new muffler. Alas I made a big mistake, I had the front flange exhaust piece upside down. Cut, flip and weld again. Then I welded the old hanger up and bolted everything back. Good as new! Except it sounded worse than before. Should have bought a flange gasket. Though I did a great job and was happy with it, the wife was not. So I learned 2 things, measure and double check said measurements, and buy new flange gaskets. I would have bought a gasket, but with my old 92 civic's exhaust, the gasket just fell out in one piece, and I just reused it, I figured with a newer vehicle the same would apply. Any way good vids Eric I always check for new ones. Ps just curious to know what make of camera you use for your uploads. Thanks for your time, and keep up the good work bro.
Thanks for making the video loved every minute of it job well done
33:12 that feeling when you put so much work into something and it works!
I had a 97 2.5TL that is very smilar to Vigor. I had lots of difficulties w/ repair of leaking distributor, leaking oil fitler mount, failed starter, leaking exhaust manifold. One common thread through all my problems...very difficult access. I was happy to sell the beast for $1200 bucks and say good riddance a couple years ago. Looks like you need to work on your weld ties where weld deposit ties into earlier weld start point. Nice video.
Way to go Eric the welderguy!
good job eric. i enjoyed watching this repair/fab video.
Get yourself a gas blower for your shop floor, best broom i've found, thanks for the video
Well done job! Your videos are awesome for guys like me. thank you
Eric, when you were tacking the new flange onto the old, I would recommend a welding clamp to make sure nothing moves. Vise grip makes some nice ones...
I bought a junk yard car about a year ago.b it's builds like these that really expand yoyrnprobl solving skills. Trying to solve a problem for as little money as possible. Normally on higher value cars I would (I am sure you would as well) actually replace the parts with the proper parts. However when you have a cheap/lower value car you don't want to spend the money for the "bolt on" parts.
Something I learned is to check for alternative parts that will also fit(,not just exhaust) like from different cars. One example of this could be, struts for one car could be $300 each but ones that physically fit but have slightly different valving from another car cost $80 per side. When it's a cheap/low value build the $80 per side looks a lot better when you only paid $500 for the car.
My cheap build had exhaust leaks, a trip to local auto parts store to the exhaust section and a couple hours of work and now it's quiet for a ton less, much like what you did.
Hehe, Eric the (custom) car guy. If this video had a theme song it'd kinda sound like "Exhaust leak hero, with rust in his eye."
That was a good build and all the right tools especially that socket flex tool. I need that.
I need those flexible impact sockets. So MUCH articulation!
wibblywobbly1234 I need an impact hammer. I believe that's what it's called that he used to push the remains of his those rusted nuts? Good for stubborn wheel bearings too.
I'm wanting the grinders. The one good for polishing a flat and the other for a round service.
Eric your face at 17:25 "PRICELESS" LMAO You were like a kid the candystore:->
Great video, really enjoyed it.
Well done!! Great vid!
great job Eric.....like ur work!!!
another great video thanks mate
this is a perfect example of doing auto work where the mechanic makes it look easy... because of his years of experience, and I would have stripped everything to hell then gotten pissed enough to have to pay someone else to fix.
hey eric just a tip on the welding on the car yes it's good to disconnect the battery, but not normally needed, just attach the welding ground toward the engine side of the weld and you should be good!
Excellent repair very international video
This is the video I need!
I havent read te coments and lots of ppl have probably allready pointed this out, but you should always use as much heat as possible on short welds. you can always control your travelspeed or even switch to spotwelding leting it cool a bit between spots. but there´s no other fix than grinding if you start your weld to cool.
try starting with a fairly low travel speed when you are practiceing, burning holes ín sheet metal is an important part of the learning process really :D
good luck!
I had to change the entire exhaust on my accord. The cat, however, was good but I had to cut all the studs the same way as eric to remove the old pieces and save it. What I ended up doing was cutting and grinding all the studs flush with the flange and drilling them out (I tried punching them out but they were in there solid). Then all I had to do was fix it together with the new parts using some new nuts and bolts.
eric the humble guy after all that.
I like the part where u weld the flange, my flange is all rusted its leaking out smoke. My flange had a curve pipe so I might just have to buy new exhaust but thank for showing this video.
I love your shop, needs a lift though. Great video as always.
Great Great job, Eric.
I've learned.
Tnx
Really nice work. Fun to watch a prj turn out so well.
I know you have thought about this... You could have relieved some pressure on the flex pipe, by fitting before you welded the 2 hole flange to the flex pipe. Had that been in the car and you tack welded the flex joint there... you would have loved the reduction in pipe pressure at bolt in time. its likely the higher pressure on the flex pipe will create a sooner end of life for the flex. :)
Stellar work! Great job.
Great video Eric! I did a similar repair on my '97 Galant last year, which has 2 flex-pipes on the frontpipe as it's a V6 with two exhaust manifolds. As if 1 (like in this video) wasn't already hard enough ;) But it's exactly how I did too, although no fun with a plasma cutter, 'need' to buy one of those someday :).
great job
thanks for the details. nice video.
I like your socket drill. I could have used that when doing my exhaust.
great fix, nice video. i love to see people fabricate parts instead of pay the stealership outrageous prices. fight the power
Eric is the best
Good fix Eric your the man
11:48 "I'm a little concerned about my length." Couldn't resist haha
Very informative video though!
Flex pipes on all cars tend to be a very common leak point. Always be careful not to over flex the pipe if you are ever lowering your exhaust pipe for whatever repairs.
eric, good video. keep up the good work.
I personally have just cherried the converter bolts and flange then punch them out. As the stud eric are dealing with are just pressed in. The hanger was well you can just buy or use round stock and bend it . For me just seems easier then playing around with the old rusted stuff
I would LOVE to that the tools you have in your garage or at least something similar for the weekend DIYer
If I were you, when you were welding that pipe onto the flex, I would just take a white chalk or a marker and just mark the exact position of the pipe where they connect, remove them both, and then attach them on the table and weld there. Also removes the possibility of colliding with something you don't want to under there!
Good job
Hey Eric, nice DIY video (again). I would recommend wetting your rag next time you're working with so much heat next to it. Would be a shame if you set your rag on fire ;).
Eric, try using the welder on 6 and f, the heats higher it will fuse to medals togeather rather then pileing on top of each other, it works for me
20:07 most manly compressor kick-in in history
Edutainment :-)
Not sure if anyone has commented on it yet, but a 4" disk grinder would cut right through some of that stuff. I would have used it to just cut the ears completely off the cat.
Nice dual cassette stereo & Koolaid man clock :)!
Nice... but what about the clock.. will we ever know LOL... Nothing better than knowing you fixed it yourself !!!!
Also, I've never disconnected the battery to weld exhaust. Get your ground as close as you possibly can to your work (ground clamp on the pipe if possible)
Good jobb!!!
