it depends what you want I did removal of the mid box with just straight pipe and then a BCS backbox which is the same as Statlers. It worked about about 250 in total. You could just get the back box and cut the current exhaust yourself as it comes with a joining sleeve and you just need some pipe sealent to seal it
