Hey all,
Pretty certain that I'm going to ante up for a catback AWE Touring exhaust system, knowing that I'll also have to deactivate the AFM on my 2018 A8.
My only concern at this point is that I still have 2+ years on my powertrain warranty and if there were any issues, I'm sure the local GM dealer would freak about the aftermarket exhaust, even if I returned the ECU to factory prior to service.

Anyone have any experience with this?

I might just buy the catback kit but only install the axleback portion until the warranty runs out, it'll just be a long 2 years until I get the pure sounds of power.
