I know some of you 6cyl guys say you have what sounds like an exhaust leak. but how about the 4cyl guys ? ever since my aftermarker exhaust was removed and another factory exhaust replaced it. Its always had that hiss sound when taking off under full throttle.

usually exhaust leaks aren't hissing noises. a hiss at WOT is usually just the air rushing through the intake system.

I don't know nothin' 'bout no stinkin' hiss.

i don't have a hiss.....

i had a tick on my vette after my headers burned up the cheap paper gaskets. good gaskets fixed that.

Yeah i get a hiss on mine... sounds more like a slight woosh though.

The only thing I get is something that sounds like a vacuum leak. Extremely hard to hear. Could be intake to.

 

[lotust]

but you all hear a noise and it not a good or performance sounding noise. More like the noise an old car makes right ?

 

[81shark]

i don't hear any noises on mine.....sounds pretty normal

 

[naiou]

No noise on mine either.

yeh i get a hiss, it sounds like it is coming from the exhaust conection below pass seat, more noticeable when driving along concrete barriers. could also be a door seal leak, dealer ignored my request to inspect at my last oil change, must try next time.

Yes this is exactly the sound i have. I can hear it really loud when driving along concrete barriers like you said. It sounds like it under my feet too. WTF

Sure glad I can't hear shit, except Faust - So Far cranked to 62.:whatwhat:

Im going to crawl underneath and have a look one of these day. it sound like its leaking or comming from before the cat. Maybe from the collector?
