Hello, I have recently had a stage 1 Revo re-map and a cat 1 Milltek exhaust fitted to my MK 5 GTI and when the car is at warmed up there is what can only be described as a rattle type of noise coming from the two rubber mounts where the reduction pipe is onto the original exhaust pipe I ma going to fit two new rubber mounts to see if this will cure it, the noise only occurs when the exhaust is warm, it was fitted by a Milltek dealer. Has anybody out there encountered a similair problem? Any advice would be gratfully received. Thanks Paul
