So i just swapped my crappy custom TBE for a Invidia V2 downpipe (heatwrapped) and Borla Hush Catback. After the install I have a strange rattle. It sounds like its coming from the downpipe/turbo area. It only occurs when I'm driving in any gear except 1st. I can hear it most at lower RPM's and it increases as the RPM's increase when in gear. However if i put it in neutral at the same speed and rev there is no noise. There is no noise when the car is parked and it seems to go away (or is drowned out) at higher rpms. The best way i can describe the sound is a very fast rattle or tapping from that side of the car/motor. I checked my tranny dipstick and it isnt hitting anything, i dont have the stock heat shield and i cant find anything my SPT is hitting. The dowpipe does come very close to the firewall but i wouldnt think it would rattle? Any other ideas to check before i lose my mind?
