i have a pretty bad rattle at 3K in my gsr. i recently put on a greddy evo2. i've already pulled the lower and upper heat shields off the cat and the piping down by the resonator. has anyone had this problem before? i've looked around for anything loose. it's def coming from the rear section. any help or insight would be great.

 

maybe the muffler's hitting the bumper? have someone rev up your car and try to see where the sound is coming from

 

check to see if your axle back part is rubbing against your subframe
