Anybody else have any problems with exhaust rattling? The spot welds on the baffling inside mine broke in a few places and caused a VERY irritating rattle noise at various speeds. If I put my foot on the exhaust shield it stops. I have the baffle out of the pipe and I'm going to wrap it in steel wool (trick my muffler shop told me) and re-weld it in with JB Weld. I'll report the results.
