you are trying to make a track car, and cant decide on an exhaust? thats like saying you want to swap out an engine all on your own, but have never picked up a wrench. dude. cmon. use some common sense. if you have an assload of a budget, get the lightest Ti exhaust considering how expensive they are. if you dont have much money, buy used. tanabes are very light weight and can be had for a good price. if turbo setup, 80mm piping. bigass turbo setup pushing 500+ whp, piping +90mm. na, 60mm. you shouldnt be on the track if you dont know these basics. set a decent goal for your car, and then think about what you need to do to it.
