After installing downpipes, this sound became amplified. I can hear it while driving at all speeds (most revs below 4000rpm; above that exhaust dominates all) always when revs are coming down (decelerating). This happens at all engine temps. I feel like there are two places it occurs. Coming down off revs, then it sort of goes away, but then returns just as the car is coming down to idle (coasting). Either way, it is louder, annoying and making me consider removing the downpipes. I have read it could either be a turbo/wastegate issue or just the actuators. I am going to take my car in next week to have them look at that specific issue.

Hi Mark - I won't speculate on something I haven't heard in person but, it sounds like something is loose - perhaps a clamp or heat shield.
Maybe even fitment issues from downpipe to Meisterschaft GTC.
Let us know once you get things checked out.
Anyone else having similar issues with their downpipes?
