I recently installed my Apexi Dunk on my '98 gsr and took out the cat heatshield (both top & bottom) cuz it was rattling like crazy. Now that I got my new exhaust installed there's rattling noise (not as loud as the cat. heatshield) coming right from the middle of the car. I think its the piping hitting the exhaust heatshield? But i'm not sure... what do you guys think? The noise is driving me crazy! Help!

 

probally is, just jack it up and shake it a little in that section that you hear rattling. Look and see if its touching anything 2.

 

k thanks
