My A5 is still on order and I'd like to know the diameter of the exhaust tips and the cutout in the diffuser on the duplex-exhaust models (3.2 and 3.0TDI), for some future mods. Anyone happen to know or willing to measure?
Peter, as I'm sure you're aware, the A5 tips are more oval in shape than they are round. As such, I measured them to be around 88.9mm (3.5") side to side and around 82.55mm (3.25") top to bottom. Regarding the diffuser cutout measurements, I can't really help you there as I have the S-line rear diffuser installed on my car.
I assume you've read the posts and seen pics of the Milltek exhaust available for the 3.0 TDI?
