I got your backon this. All the muffler shops, while making mme mad by saying they wouldn't touch my Bronco without a converter on it, said that if you get rear dual exhasut that the fumes rise back into your truck when your for say sitting at a street light.
most of the new flowmaster are aluminised , and hold up verry well , id look for a used set of flows and have a shop run them stright back with 2.5 pipe and eather exit by the tire , out the side (be sure to tell them if want it in front of the tire or behind and make it VERRY clear , not an easy mistake to fix ) and broncotough is sopt on with what he said ive got that problem now , or run it stright to the back , forget the tips for now if money is tight , the pipe can always be cut back and tips welded on later , bang for the buck , whole thing should coast around 250-300 and you'll have something you will really be happy with , also , if possable id hold out till you can find some stainless steal tips if you do much mudding as the chrome wont hold up for to long and will pit and rust badly
