H23 or H22?

I'm guessing that if you have a 4th Gen VTEC, you could probably make one fit. Though i'm not sure. i'd call king motorsports and see what they have to say.

if you've got an H23, you might be able to get one to fit with a little modding/fabbing, but then again, with a 1000 dollar header i'm not sure if you'd be comfy doing that cuz i wouldn't.

i know the SMS header works for both 4th and 5th gen VTECS, and maybe for the H23 as well, with a little work.

i'm fairly sure mugen had an H23 header at some point but i'm pretty sure they're not producing any these days.

oh well, get your mugen swag while you can, before it become M-TEC god what an ugly name.
