miko_supra Posted March 5, 2008 Share Posted March 5, 2008 did a search, but couldn't find anything although im sure its been asked may times before... are the 2nd decat pipes any different on a uk spec or j-spec TT. and does it matter what diameter it is (2.5/3")?

keron Posted March 5, 2008 Share Posted March 5, 2008 did a search, but couldn't find anything although im sure its been asked may times before... are the 2nd decat pipes any different on a uk spec or j-spec TT. and does it matter what diameter it is (2.5/3")? the same....as far as i know. only the 2nd is the same. 1st is definately different. 2.5'' or 3'' is fine. the only thing it might have/not have is the hole for the cat sensor...

Dazzi Posted March 5, 2008 Share Posted March 5, 2008 The cat temp sensor is only in the 1st cat FYI, and Sparky... how did you make it louser? Link to comment Share on other sites More sharing options...
miko_supra Posted March 6, 2008 Author Share Posted March 6, 2008 The cat temp sensor is only in the 1st cat FYI, and Sparky... how did you make it louser? theres two in the uk spec iirc. one after the second cat too? british like monitoring temperatures Link to comment Share on other sites More sharing options...

Can't go around without 2 watching you Link to comment Share on other sites More sharing options...

Louser is cool for Louder.. Aiyee! p.s - I meant 'louder' Link to comment Share on other sites More sharing options...
Homer Posted March 6, 2008 Share Posted March 6, 2008 I thought the UK and jspec 2nd cats were different? The UK has a 2nd oxygen sensor in one of the cats (can't remember if it's the 1st or 2nd one). On a TT or hybrids 2.5 diameter is plenty, you only need more for large turbos Link to comment Share on other sites More sharing options...
