DannoSupra Posted August 30, 2007 Share Posted August 30, 2007 Has anyone put a 4" Turbo back exhaust on a UK before? Any Gains? Quote Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted August 30, 2007 Share Posted August 30, 2007 With std twins its a waste of time, 2.5 is adequate, i have toyed with going to 3" with hybrids but i doubt it would make much difference. Quote Link to comment Share on other sites More sharing options...
Supra-Brett Posted August 30, 2007 Share Posted August 30, 2007 i am far from an expert on this, but i recall from previous threads that if you put a bigger exhaust on, then you wil only need to put a restrictor ring in it anyway to reduce bore size so that you dont overboost. Not entirely sure but i think thats what has been stated on previous threads. Quote Link to comment Share on other sites More sharing options...

matt k Posted August 30, 2007 Share Posted August 30, 2007 Wouldn't matter on a UK car as the wastegate is bigger and holds without overboosting. Quote Link to comment Share on other sites More sharing options...
