When driving straight, it usually occurs during or atfer you take off or when you hit a bump, right??

 

I recently installed a test pipe to finish out my turbo back system and I found the same noise after installation, upon investigation I noted that the flange on the test pipe was hitting the heat shield and causing the noise. It was particularly bad when I was at Idle stopped or directly after hitting a bump. I fixed it using an old rubber exhaust hanger, by wedging it between the flange and the shield. Kind of hood but I havent heard the noise since and there is no sign of wear anywhere so, overall I am happy with it.

 

my stock dp makes annoying noises sometimes like a rattle its only when its hot hopefully soon enough it wont be stock

 

wow its so much trouble to even upgrade an exhaust.

evo's suck

 

yeah thats when it happens, or when taking a U turn.
whats causing the sound exactly? and how do i make it go?

 

Problem Solved.
o2 sensor touching the heat shield.
