i am wondering if i could put the jdm itr header on my eg with a b16 swap and not have to modify it. i am currently running a 99 si header which is the exact length i need without having to modify anything.

 

The length will be close enough, but the larger collector will require a custom cat.

 

i already have a 2 1/2 in and out cat since my car was supercharged and i am pulling that stuff off including my kamikaze 4-1 with 2 1/2 downpipe that is why i want to know if this header will work since i am replacing the kami for a NA application

 

if i remember corerctly, the flange will be off..they wont bolt on

 

is it the same flange as the usdm itr?

 

No.

 

yes, it will fit...
