Ok, soon im gona be getting underdrive pulleys, headers, and exhaust, proly a straight back . the straight back im proly gona get a custom 2.5inch one, but for headers and pulleys , what brands are good? i know smsp is good but its too expensive for a header

also what other bolt ons could i do? would a fan switch and thermostat do any good? the mugen ones..

 

I would get orthodox or aem for the pulleys. As for the header save up for a good one. But for the cheaper range greddy seams like the way to go.

Other boltons... Cold air intake

I personally think that the fan switch and thermostat are dumb because why would you want it to open at an ealier degree when the water is gonna be hotter than that all the time anyway. You will just put more wear and tear on your water pump for mo reason at all. Just my.02

 

Header....

Go to the prospeed site and check... seems like a pretty good deal for the gains. You can PM him on this site, and do a search for the topic as well. They have a new design header for H22 that is supposed to flow as well as the one they used on the H22 accord. anyway, good luck.
