my gtt has developed an exhaust leak..only when you start it the first time it briefly sounds like a tractor then goes back to sounding normal..i had this prob a while back and it had broken a manifold stud..we checked the manifold and is not warped at all so we replaced the stud but now it has done it again...any ideas why it would keep shearin studs?? i assume it is the same problem again and also does anyone have a factory bov as mine has been repaired numerous times but keeps coming apart at the back.
cheers
