Exhaust leak?

hardhitter · April 5th, 2008, 10:00 PM

During normal driving I can hear what sounds like it could be an exhaust leak but I'm not sure? I have l/t headers, prochamber and magnapacks. How would I know if it's an exhaust leak or just the way the exhaust sounds? Should I be able to hear noise under my feet or just coming out of the rear of the car?

Depends on where it is coming from. Check all the fittings, especialy the header gaskets.

I can't really get to the header gaskets. They have locking bolts though.

the locking bolts will hold them yeah, but everything must be tightened correctly lol! when i get on it from like 2-3k it kinda sounds like a have a leak from inside the car, its pretty subtle.
just have someone with a good ear check it out from the outside.

Mine only sounds weird when I drive normally. When I give it a lot of gas it sounds great. I had a shop do the headers and midpipe.

get under and check all the connections, thats about the only way you will find it. If its a header to head leak it will sound like its coming more from the front of the car
