I just bought a used apr dp but it doesn't have the reducer to mate with the stock catback. I have check the apr website they don't sell it. Does anyone knows where can I buy the downpipe reducer and the exhaust size diameter of it?
I am planning to buy a downpipe or tbe for my mk6. it seem like awe has the best of the deal, however it is only 2.5 in. I want to know will it make a big difference on performance or tuning? because like apr and unitronic ots tuning are base on 3 in pipe.
