Got my 2.5" Omnipower test pipe in the mail yesterday. The header flange is extremely wide, and I don't think it's going to bolt up to my DC headers? It doesn't bolt up to a stock header... what's the deal? I don't think I was sent the wrong one, and I know a lot of people use it... so how did everyone get these on?

 

mine was fine Everything fit.
car: 94 civic hb
engine: b18c1
header: 93 gsr header
ex: tanabe racing med. for 92-95 civic

I got the non-jdm one though not the 2.5

 

Yeah well my stock A pipe went inside the test pipe, literally.

 

u sure u got the 2.5" collector version dc sport header?

No, that I know I don't have. I was planning on upgrading to a 2.5" Kami for the SC, but I figured the test pipe would still bolt up.

I'm guessing this is my problem.

 

i think the omni jdm test pipe is specifically for the 2.5 inch collector on the jdm itr headers and other headers with 2.5 collector

Umm, the reason it is called the "JDM 2.5in" test pipe is because it is made to bolt up to the JDM ITR header with the 2.5" collector. If you want to use a USDM header, you need a regular test pipe.

 

Alright, thanks guys.

I needed to buy a new header anyway, so looks like it's next on the list.
