What all you got left to buy? That exhaust should keep you busy for a while. That GV is gonna give you some special issues. Especially with that x pipe.
W/s and rear glass rubber then seats. Yea the GV is a problem but the guys at Pypes were well aware of the GV in A bodies and should not be a big problem.
Would install it now buy behind the curtain that my car is in there isn't enough room to do anything to much crap piled in there.
