Hello Guys, quick question, i currently have a B20Z in my DA with a Megan Racing 2.5" 4-1 Header and a Tsudo Catback Exhaust System 2.5" for a DA, i want to trade my Megan Header for a 97 Spec R 4-2-1 Header with 2.5".

Here's the dilemma, are these headers the same lenght or would i have to cut n weld or extent something from my exhaust system in order to fit, i would love it if its plug n play basically so i don't have to hassle that much

Thanks in advance!

 

The Megan Racing 2.5" 4-1 header was based off the ITR header design. So the dimensions/length should be the same as the ITR.

 

yes but based on 98spec R, since 97 spec R comes 4-2-1, i don't know if its the same length to the CAT/Test Pipe, so thats what i want to know

 

yeah, the header should have the same length. I got my in with no problem. However, I'm using a test pipe so I wouldn't know if the holes line up.

 

it should. the 97 ITR is basically a GSR manifold on steroids. the length, cat and exhausts are compatible between the 96-97 and 98+ engines.

 

yes very well, thank you guys!
