alright, my 91 currently has a 3" to 5" and turns down right around the middle of the bed. but its oakie rigged. so i can either take it to the local shop where my buddy works and get the 4" down pipe and go in to 6" and turn out the back, with all new hangers. or i can put some stacks on her. everything on the truck is black so i though some fat chrome stacks would really stand out. any help?
