If you are running a 2" exhaust, why wouldn't you want to use a 2" collector?


Just run the DC header.

 

i hear a lot about the 2.5 inch collector, that it gives you more power....but im going to try the dc sports header....thanks alot!!!!!!

 

If I'm not mistaking the ITR header should be a 4-1?

read his first post. it could be a typo. but anyway, this thread isnt about headers and could be's. it's about which SIZE of collector. and that question was already answered.

 

Only the 1999+ JDM ITR has the stock 4-1 header. The 1996-1998 JDM ITR simply has a 4-2-1 with a cast manifold, but with a 2.5 inch collector.

 

corect the jdm 96-97 engine came with a 4-2-1 and the collector is huge.....i put the 4-1 dc header and ran a straight pipe no cat....but my car shakes a sh*t load everything shakes inside.. would i be better off getting a high flow cat????????
