I have a 4-2-1 DC sports header for sale, search my post in the classifieds. The 4-2-1 design is better for low to mid range power as compared to 4-1 headers which peak at top rpm ranges. I bought the 4-2-1 because i felt it was better for the street rather than the 4-1 which is more for circuit racing. Exhaust systems basically do the same thing, ure not going to get that much whp from just adding an exhaust. I say maybe 2-10whp max, its more important to look for the right diameter piping, straight flow, build quality, and lastly sound and looks. I have an RS*R stainless cat-back and i can't complain. Have fun man
