Allright, I need to know exactly what the b16a jdm came out of. I need to buy a header and I have to tell them what type of car the engine came out of. Is there any american equivilent that I can tell them so that things will go smoother? And what brand do you people think works the best? 4 to 1 or 4 to 2 to 1?

 

Any B-series header will bolt-on. If they need a reference, tell them the Del Sol vtec or 99-00 Civic Si. Everyone has their own favorite brand, for me I like DC sports for the quality that you get for the price.
