Hey all, I just installed a new cat-back system the other day and it was working fine for a couple days but today I started the car and got to driving. About 10 mins into the drive once the engine was warmed I started hearing this rattle at low rpm, sounds like if you shook a soda can with a bolt in it. I hear it especially when I engage the clutch. Thinking it was an exhaust leak I went back and reset the gaskets and re-tightened the bolts but it's still there.

Any suggestions? It's weird cause you can barely hear it outside the car, but inside it is very loud.
