Hi guys, hopefully a quick and easy question.
i own an a3 2010 1.4tfsi (125bhp model) and I am trying to work out if a downpipe will actually be benefitial.
currently the car has these mods : forge bov adapter, vtech custom tune, custom made cat back exhaust and eddy power carbon fibre cai.
im trying to source one and only find one from supersprint.i am still unsure if it will even give me any power gains or if my other brands make such a downpipe.
if you guys have any advise or can offer any assistance that would be greatly appreciated
