my stock gsr has a cracked manifold that i really want to replace. ive been looking at the jdm itr header but its hard to tell it its worth it by reading and looking at pictures. it looks like it becomes discolored after awhile but i dont care about that. i also have looked at the jdm dc 4-1 header. wat would be a better "bang for my buck?" im looking for more high end torque. also, i want to keep the stock exhaust for the time being so i know ill need a reducer to go from 2.5" to 2.25". any insight would be great.

EDIT---does an jdm itr header bolt right onto the b18c1 block? thanks m8s.

If the DC has gains over the stock jdm itr header, it won't be much.

Unless you spend 500+ on a header, with an already nice setup,
All of the cheaper headers aren't going to vary much in hp.

 

I've seen a few dyno's testing diff headers..

One of the last one I saw was a GSR engine and they tested 5 or so diff headers.. ITR, aftermarket ITR.. a 4-2-1.. a 4-1.. and I cant think of the other.

The DC-Sports 4-1 pwned them all.

 

anybody have any dyno readings for me....?
