i am in the market for a header. i was reading about a few and the DC 4-2-1 2 pc looks the best but there is one sticking out in my mind. the HP racing 4-2-1 2pc. HP claims their headers make an average of 3 horses over DC. i didnt believe it but i saw dyno charts. they are stainless and cheaper than the DCs. quality?(prob not) what do you think? any recomendations other than DC or HP? thanks
