What kind of headers could I use on my LS VTEC. I have a b16 Head with a b18 block.

Other than what I'm already running.

there are alot of headers out there do some research and get one that has the same diamater as your exhaust if you want to spend some money go JUN if not just get a DC 4-1 jdm.

So when I buy headers I buy headers for an LS model car, not a GSR I would think

First off, you have an inline four motor, so have one fucking header.

Second, your header needs to clear the oil pan, and bolt up to the head, fortunaly for you the header bolt pattern are the same, and you only have to worry about whether it will clear the block and bolt up. Get one for a 1.8 motor, GSR, LS, ITR whatever.

Thanks for the help. It helps tons now!
