I just bought a 01 chev dmax and wonderin what im supposed to do now!!! ive been reading some threads about tranny mods? what type of mod and how much? all im doing with this is pulling a trailer(4 place inclosed alum. bumper pull) but when im not i wanna turn heads! I also want to know what is the best exhaust system for the 01... cat back or the whole system? is 5" too big? I would also like to know what brand of intake system is most commonly used on this bad boy? i want to do these mods before i put the edge in it. i love the truck!!!! Ive always been a ford man but im really diggin' this dmax!
