Thank you for your opinion and advice. Much appreciated.In terms of performance there is a marginal difference if any. It's mostly for sound change.
If you go for the 2.0T, it could effect performance a bit more, but you'd really need a turboback with a tune in order to see any noticeable difference.
Personally, I'd go for the cheaper axleback option unless you hardcore offroad and want a catback that gives you better clearance, because the sound difference is usually barely noticeable and the performance difference is basically non-existent.
The thing that effects the sound the most is the type and size of muffler you go with, which is located on the axleback portion.
Cat backs are most likely to affect performance and drone levels because they replace the factory resonator.Other than the obvious, that one has extra pieces, what’s the benefit of the catback over the axleback exhaust?
