I installed my Pacesetter LT's about a week ago and my y-pipe rests against my torque arm and vibrates like crazy. Anyone else have this problem?

 

Yep, I had the same problem. As a temporary fix, I wrapped that portion of the pipe with some header wrap to dampen the impact. I have since upgraded the torque arm to the crossmember mounted style so now the torque arm comes nowhere near the y-pipe.

 

I remember reading that somewhere, I think I may do some "custom clearance" work this weekend with a hammer.

 

69GTO96Z - What kind of torque arm are you using? Factory style or aftermarket?
