So i have been doing a few weeks worth of research and have found a ton of reviews and post's on what i have been looking for but nothing really answering my question.

I own a ej1 coupe with a b17a1. As of right now it has a light weight flywheel, 3" intake, itr intake manifold, cheap 4-1 smashed header, test pipe, and 2.5" exhaust.

I plan on doing a rebuild within the next coupe weeks that will just consist of new oem parts, but also a buddyclub thin head gasket which should bump compression a little.

Now to the question, do i purchase the new RMF Narrow header which i have read really nothing but good about, or something else i have kinda had been looking at, the Kamikazi header that has the 2.5" flange?

I have read the RMF makes great power even on stock motors, which mine basically is and will be, but i havent seen to too many reviews on the Kamikazi. the ones i have read have been good ones but have been mostly used with Superchargers. any thought?

thanks

 

i wouldnt go with the kamikazi unless you were planning to supercharge your motor maybe. I would go with the rmf.

 

Toda header if you are a baller, JDM ITR header if you are more budget conscious.

 

yea im on a tight budget. but i think as of right now i am going to buy the rering and bearing kit and replace my valve seals and headgasket and see how she runs and just save up for the rmf.
