Anto Posted June 3, 2013 Share Posted June 3, 2013 As per title really, I picked up a second hand but never fitted 2nd de-cat for my N/A for a very good price but I'm now not sure if it will fit. Inner dia is 3" but before I pull anything apart just want to know if this is the right size. My understanding is that the TT and N/A 2nd de-cats are the same but I've seen references to a 2.5" version and am now confused. Will it fit or not? Help!! Thanks....

Graham1984 Posted June 3, 2013 Share Posted June 3, 2013 I thought they do fit although it would just have like an interior rim so to speak, I have a manifold that is 3" to a whifbitzs 2.5 2nd decat and it's fine. I am sure someone more intelligent than me will be along soon though. Quote Link to comment Share on other sites More sharing options...
