Exhaust leak

[jhandy]

I had the same issue. Fixed it once by removing clamps and putting exhaust pipe sealent then clamping together. That lasted for a years now.

Muffler Cement 35958 Dynomax

is the one I used. But there are many types.

I have the same leaks and it drives me nuts. I haven't figured out which way I want to fix it yet. I may try that exhaust cement stuff just for the hell of it.
I think a better way to pin point exhaust leaks is to go buy a $10 stethoscope from autozone and use that.

I was able to find 2 leaks at my header I was wondering if anyone has come across also. I found that I have a leak on both sides in the exact same spot. See attached photo.

The leak is where the pipe goes into the "flange." It isn't a very large leak, but it is def a leak. I just found it to be weird that both sides are leaking in about the exact same spot. Has anyone else found the same thing?

Jake, your leak is an entirely different beast than the one I was describing near the muffler, but I would venture to guess that yours has been caused by a stress fracture. It looks to be in a spot that would see maximal stress from applying a load/force to your exhaust system. Do you have an aftermarket muffler? In that case the different muffler has a different hanging location and thus could have exacerbated the stress placed on your header pipes.

Also as a note, I would not bother using the cement on your header since the outer surface you are pointing to will see 600+ degrees C and no exhaust goo will withstand that, short of welding.

At the rear end, however, the exhaust goo sounds like the perfect fix and in fact I will try it out and see if it seals up nicely.

I have no idea why they would leak there and yes I agree that no goo should go near there. I couldn't think of any reason there would be a leak there, but it is literally in the exact same location on each side. It's def not the main cause of my exhaust leak noise though so I am not too worried about it. I may try taking off the U pipes, cleaning them up, and re-installing them with some muffle goo. Can't hurt to try at least.
