A while back i put a flowmaster cat back system on. Went pretty good. Checked all the clearances and drove it. Figured I would drive it a bit to make sure every thing was clear before I put welds on the pipes.

I've put around 400 miles on it since then.

well yesterday I was hearing some clunking around 1200 rpms, and sure enough the right side pipe is loose. That side is pretty tight on clearance to start.

Guess I'll get under there and reposition it and tighten up the clamp. and start over.

Any other ideas?
