im swapping an itr motor in my 91 gs i want a header that will fit not have to cut my cross member but not be to restrictive i searched the megan 4-1 sounds good but have to cut my cross member
Whats wrong with the itr header? It’s a very good header. 2.5 collector is restrictive at all.
it comes with a manifold no header even though will the jdm itr header fit with out mods to our crossmember?
I’m not positive. The JDM ITR header is a 4-1 1 piece header, and 1 piece headers usually mean notching the crossmember.
It depends on the year of your ITR engine. Only the 98 spec ITR engines had the 4-1 header, which requires notching of the crossmember.
96 spec ITR engines have an exhaust manifold that is near identical in size to and OEM exhaust manifold, but with a higher flowing collector.
