ok after a couple hours of fighting to get the h-pipe on I start the car up and I have one mean leak comming from the drivers side exhaust manifold where it bolts to the h-pipe. I tried unbolting it and moving it around a bit and that helped but its still quite the leak. has anyone else had this problem? any help would be appreciated. btw '00 GT vert

 

Often times on that side the studs coming from the manifolds aren't threaded all the way down, so when you tighten up the h-pipe to the manifold you think your tight because the nut is bottoming out where the threads end, but in reality its no tight all the way. Get some new fully threaded studs from napa or something and replace the stockers.

 

how would i go about getting the old studs/ bolts out they seem to be pretty well stuck up in there...

 

double nut them and back em out

 

thanks
