Can't find answer on here and probably a noob question.
Looking to get a downpipe and it seems most FWD MQB downpipes are listed to fit both GTI and TSI. How is this when Catback for Golf is 2.25" in diameter and GTI is 2.5". Do they come with an adapter for both?
And to the more important question.
If I get a 3" downpipe and want to mate it with stock 2.25" exhaust, do I need 3" outer diameter to 2.25" OD or 3" OD to 2.25" ID or something else?
Can I just get a generic reducer or does it have to be from downpipe manufacturer?
