If i go with a set of 1 5/8 full length headers compared to a 1 3/4? My mods are in my sig, but i was sort of curious if it was that big of a change. I plan to do more major engine work later on in the next year or two(cam, heads, intake porting). But by then i would have money to buy the bigger headers then. Anyways i want something that is pretty good and i thought get full length headers at least, but just a smaller size that i can afford.
