Muffler Replacement- Clamp or Weld

Pretty simple- were you able to just cut and clamp your new muffler on, or did you have to weld it in?

Looking to replace JUST the muffler, and I'd like it to be as inexpensive as possible.....so if a muffler + sawzall + muffler clamps + Bud Light = new muffler, I'd be a happier boy than adding 'go to exhaust shop' and removing 'muffler clamps' and 'Bud Light' from my algebra equation.

Re: Muffler Replacement- Clamp or Weld

use the stainless steel 3" wide strap clamps, they seal better, a little more expensive ($10 each) but worth it.

It's all a matter of personal opinion. Some people just like the "secure" feeling of knowing their exhaust is welded. Other's, like me, are just fine with having it clamped on....

Weld. Nothing beats it.

Clamps do their job but I still rather have mine welded.

Exactly, the only time we use clamps is on STOCK replacement parts that carry our lifetime warranty. It's quick and painless to unclamp and replace a muffler vs. adding pipe and welding. IF you look under my vehicles you won't find a single clamp, just some pretty welds

Re: Muffler Replacement- Clamp or Weld

i just put in a new muffler the other night and i welded it in. ive heard from ppl that clamps eventually come loose and there is a strong chance of a leak, welding was simple took bout 20 minutes of welding and it was done. but make sure if you do weld u take the exhaust outta the truck otherwise the electrical current from the welder can screw up electrical sysems. but my preference is welding and it looks so much cleaner

Re: Muffler Replacement- Clamp or Weld

Re: Muffler Replacement- Clamp or Weld

yup, i had one shop do half weld/half clamps, i just took it back and told them to weld the whole thing, much less chance of leaks.

Um.... Not really. Only if you ground it badly. How the hell are you supposed to weld the entire exhaust in and then get it back over the axle? Drop the axle?

Re: Muffler Replacement- Clamp or Weld

^ This is why I clamp. It's tough getting the gun over the top of the system. If you can, chances are it's not going to be a good weld and you're gonna have holes in it anyway.

There shouldn't be any chance of leaks of you use a clamp the right way...

Re: Muffler Replacement- Clamp or Weld

A little tip for people who clamp and have leaking, try getting some tinfoil and fold it so it's about 3 to 4 times the orinal thickness then wrap it around the pipe and carefully insert it into the other one. Then put the clamp over it and tighten it down (it can be a pain but for the people who don't want to weld it works great). The tinfoil wil create a better seal around the tailpipe.

I was also wondering if there was some type of grease that would do the same job?

Tinfoil Does work. its like having a gasket somewhat(doesnt expand with heat) but will help with leaks get some Coupler band clamps.

Re: Muffler Replacement- Clamp or Weld

Yeah I had to do it on my car because one of the pipe ends was a little mishapen and I didn't have the tools to fix it so I used tinfoil and it worked great. Heck still on there but a little more dirty than when I first put it in there.

Re: Muffler Replacement- Clamp or Weld

even if grounded properly, welding exhaust while on the vehicle can fry major electrical components. ground leads on welders tend to heat up and build resistance. when this happens, the electricity can find another source to run to. the safest way is to engineer your exhaust system to have flanges fitted and welded in line where needed for removal and it makes welding so much easier and stronger
