After putting on my slp loudmouth, I'm getting a loud clunking coming from underneath my car. It only happens when I take off fast, the pipes are tight so I'm not sure where the problem is. Any thoughts would help.

My flowmaster cat back done the same thing. I had to have my tailpipe mounts re-fabricated because on acceloration, they moved just enough to hit body brackets behind the axle. The tail pipe area is very tight and not a lot of room for error without hitting something.
