Have you installed your own kit exhaust?
I've done several kits and cobled togther my own with use of a flowmaster over the axle universial aa well as there pre-bent over the axle pipes.
It just takes time and effort. Keep the temper down and walk away.
Also, remember, the car should be on ramps, not jack stands, theres a huge clearance difference when you take the car down off of stands.
Yea... guess how I know...:sad8:
