I recently took off my mufflers so i can run straight pipes. But now every time I go over a bump in the road my exhaust knocks against the body of my car. Does anyone have suggestions what I could do to keep it steady?

 

Your OTA have nothing supporting it so it's going to hit until you have the exhaust shop put on the straight pipes and hangers.

 

The axlebacks help support the portion of midpipe that goes over-axle. Without the axlebacks' support, the remaining pipes are just flopping around. In all honesty, I think you're being foolhardy for running open pipes that are under the chassis (unless you're looking to asphyxiate yourself). You can probably get a muffler shop to bend some pipe for you with hangers where the stock hangers are.

 

Get SLPs, problem solved
