ok, on saturday i lowerd my car and while i had the car up in the air i figured i would loosen the prochamber and then lift it up some as to not drag... well i got it to go up about 1" as i had just slapped it on there before.... since then i have been tracking down a leak that i couldnt find then... so tonight i just jacked the car up and made sure everything was tight, well everything was fairly tight, i snugged down the prochamber a bit more and that fixed SOME of it but the bolts going from the midpipe to the manifolds are REALLY tight but the leak is up there....


whats weird is if i listen from above it sounds like its between the back of the drivers side head and the firewall... i put my hand all around the connection for the manifold to midpipe connector and didnt feel any gap like i nomrmally would. ive already checked the plugs, and they are all tight...

what could it be?


btw its an 04 GT

Did you grind down the pins that keep you from overtightening the midpipe to manifold? I had to take mine to Midas and have them shave them off. It made a world of difference.

Common leakage area on our cars. Make sure a gasket was used and get the pins ground down. I know the exhaust shop that originally did my x-pipe years ago had to use the gasket and some exhaust sealant "goop" to prevent a leak on the passenger side.
