Hey guys, its been awhile and il cut to the point cus i gotta leave in like 3 mins. My tailpipes are rattling on my back end (they hit up against the top there) when i put the car in reverse (low rpm's). how do i stop it? Thanks in advance

 

If they are properly secured with the right clearance there will be no rattle.

 

Check your tailpipe mounting. Might take it to a muffler shop and have them put it on the lift. I bet they can adjust of fix it in minutes.
