Paulvti Posted July 2, 2013 Share Posted July 2, 2013 As title states,Do I need a 2" or 2.25" for my MC2? It has a power flow car back system on it but standard manifold, Thanks, Paul Quote Link to comment Share on other sites More sharing options...
KieranEG6 Posted July 2, 2013 Share Posted July 2, 2013 2.25" decat UK length. Don't think there is a 2" as such. Manifold flanges are usually all a 2.25" joint or the JDM/ aftermarket 2.5" Piping on the 2.25" decat will be nearer 2" most of the time.

Paulvti Posted July 2, 2013 Author Share Posted July 2, 2013 And I have a PLM 4-2-1 toda replica but its 2.5" collector and I can't find a de-cat pipe that reduces from 2.5" to a 2.25" Quote Link to comment Share on other sites More sharing options...
Paulvti Posted July 3, 2013 Author Share Posted July 3, 2013 My local exhaust place told me they would cut my collector off my manifold and sleeve it! I don't bloody think so lol Quote Link to comment Share on other sites More sharing options...
KieranEG6 Posted July 3, 2013 Share Posted July 3, 2013 Just fit your manifold with a 2.5 decat. Pretty much All 2.5 decats run 60mm piping anyways which is only about 2.35". As long as your center flange 3 holes line up as they should then a 2.5" (2.35" reality) decat will be fine. Otherwise get a 2.5 decat cut and stepped down to 2.25 at the center entrance either way you will have s step from manifold to center. Unless you stick with a. Standard sized manifold 2.25" which is dump. Quote Link to comment Share on other sites More sharing options...
Paulvti Posted July 3, 2013 Author Share Posted July 3, 2013 Ok ill need a de-cat pipe either way so ill just order the 2.5" and have a play about with it Quote Link to comment Share on other sites More sharing options...
Paulvti Posted July 3, 2013 Author Share Posted July 3, 2013 Soooo where do I get an adjustable 2.5" de-cat pipe from? I can't find any, I don't mind buying a none adjustable one but they are apparently always the wrong length.... Quote Link to comment Share on other sites More sharing options...
