i have a greddy EVOlution 1 the first one eva came out. for an integra.
should i get greddy headers? or should i get dc headers? which would give more performance. or better flow

 

If you got Greedy stuff to start with try to stick with it, if you ever sell your car later it will make it look better as far as not mixing too many parts together. Saying that I got Greedy stainless steel headers and their the 1piece version, their basically new, bolted them on my car but need cash (just dropped the engine in and car is off the road) and since I dont got a complete exhaust I'll just put stocks back on, they got for $400 but if you want them $250 takes them. email me dav_680@hotmail.com if your interested.
