Ok so I was highly considering buying the Invidia N1 race exhaust for my 05 STI and i was reading there are issues with it mating up with the stock downpipe. So i looked at a few forums and people say the Invidia V2 downpipe had issues mating up and would make the exhaust not fit totally right... does anyone have any suggestions on what to do? are there any adapters for the exhaust and the stock downpipe or what about buying the Invidia V3 dp... help?
