I been thinking about upgrading just not sure which to look at or do and how does this effect my Audi warranty I have?
Does a cat back system do anything for the performance or do I need to look at a full system with sport cats and stuff?
Sorry to sound like a totaly newbie, but im still reading up a lot about the VAG engine and stuff, just want some ideas and thoughts please.
