I have a 2.5" tsudo exhaust system and sometimes when I'm idling i can feel the piping rattle underneath me. It's not the bolts but the piping itself that rattles. Anyone know how i can stop this? thanx in advance.

 

maybe its hitting the exhaust heat shields underneath the car or maybe hittin a part of the suspension??

 

Muffler bearings.

Seriously: The heatshield around the cat has rusted and you need to rip it off.

 

pipe could be broke. mine was radeling too because the pipe was broke.
