These guys all have good ideas. As far as tru duals do NOT I repeat do not get it custom made you will sound like and outboard motor on a bassboat if you like that than go for it. I got my h-pipe from MAc for 159 and put flows on it. I started my buddies 98 cobra next to it and it sounded idenical until you get above 3000 RPM. Also get underdrive pullies from MAC. Get 3.73 gears but make sure they are from Ford or you will have problems. Any more questions email me
