Hey, i bought a zpi s-pipe, and it doesnt fit correctly. when i installed their was a gas leak on the header side?? anyone know why??? and how this could be fixed? thanks!!

Well, you need to give us some more clues. Is the gasket installed?

yea the gasket is installed....

yea the gasket is installed....

Not sure then without some pics. There are many people that have the ZPI S pipe installed with only a few that had any issues. I would do a search "zpi and pipe" to see any info.

Did you try calling Kenny at ZPI? They are open on Saturday now.

i had all types of problems with the s-pipe as well. do u have an aftermarket header or exhaust? i ended up having to cut some of the piping in my CC catback and having it welded back together at a slight angle to get the thing to fit properly. i don't even really feel a difference-but, i also don't have a header installed.

everyone has had these problmes and everyone has fixed it themselves in one way or another

i had teh same problmes

the rear flange, i just used smaller bolts and nuts

the front flange, i tighened in 1 side, then i stuck a smaller bolt nut washer through and tighened it.

i checked it after 1000 miles. everything is fine

if you dont trust yoru own install. just tak it to a muffler shop.
im sure they will do it for 60 or 70
