As of right now I only have a AEM Short Ram. But friday I should be receving my exhaust.TegSox said:You won't need headers, you only need one header.
There is no one "best header", there's only the header that works best with your engine PACKAGE.
What is your planned setup?
Where do you want your powerband to be, where do you want your peak HP to land?
What parts do you have on the car right now?
Alright but which one will give me the most HP?PogKai said:Better top end? go for a 4-1 design
Well, not really. The collector is too big and would put his peak HP far above 7,000 rpm. But if he was also goig to do a mild cam setup in the future, then the JDM ITR header would be a fine choice. It is the best "bang for the buck" 2.5 inch collector headers you can buy., but on a GSR with just bolt-on's it a little big.209SpoonDC2 said:the stock 98 spec JDM 4-1 header is a good choice for your stock motor.
