2 1/2″ inch pipes would be overkill on the little 215 V8. I used a local muffler shop that made a 1.75″ true dual system that exits right behind the rear wheels with chrome tips. Walker #17910 mufflers are only $19.97 from Summit. They are oval shaped reverse flow and are only 3.25 inches thick, 7.75 wide and 1.75″ in and out. These mufflers will still allow for enough ground clearance.
