dibbleyuk Posted April 9, 2008 Share Posted April 9, 2008 Just curious ive noticed some people have 2.5" decats and some are using 3" which are the best ones to go for? I know most aftermarket exhaust systems are 3" so i would of thought it would be best to have the decat pipes to match? Thanks Guys Duane (ive tryed searching and was unable to find much info) Quote Link to comment Share on other sites More sharing options...
Scott Posted April 9, 2008 Share Posted April 9, 2008 3" is a nightmare for clearance. AFAIK 2.5" is plenty for most people running BPU and possibly small single turbo's. Its only when you are looking at pushing serious volume that you would need 3". I think Scott =op Quote Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted April 9, 2008 Share Posted April 9, 2008 Yes i think you are fine up to about 500BHP then 2.5" becomes restrictive. Quote Link to comment Share on other sites More sharing options...
D8MOA Posted April 9, 2008 Share Posted April 9, 2008 :D3" sounds better Quote Link to comment Share on other sites More sharing options...
