trim it?
my greddy sp2 was seriously banging and smacking my type R rear lip like crazy. Luckily I was able to trim around and behind the lip and 95% of the time now I get no banging. Sometimes when I reverse it bangs, but only if I'm reversing into a speed bump or something.

some people might reccomend polyurethane hangers, but that might cause more vibration towards the front of your car.

i have a DC TCS with a xenon bumper and it use to do that. when i took off the bumper i noticed it was melting, so i took a piece of metal and screwed it into the bumper where the exhaust was hitting. no more problem.

move the exhaust down. when i tie mine to sit close to the bumper to have it centered, it hits it sometimes. just lower it by bending the hangers or have shop do it.

well it moves around, stuff gets old, etc. it never stays in the same exact spot.
