68-72 Cutlass Supreme 442 F85 350 Dual Exhaust System. Exhaust system is for 350 cars that have tailpipes that use exhaust tips. We source these exhaust systems from GM’s Original Equipment Manufacturer. This means you get an exhaust system that not only fits like the original, but it sounds like the original as well. This set fits like the OEM set did. It does not fit like a custom show exhaust. (TIPS NOT INCLUDED-SOLD SEPARATELY) Exhaust sets come with head pipes, mufflers, and tail pipes, in aluminized steel. Aluminized steel looks like new original exhaust but unlike the original mild steel it wont rust and will stay looking shiny new for decades. HANGERS SOLD SEPARATELY For muffler hangers see part number EX871 & EX870. For tail pipe hangers see part number TPH6869 or tph7072.
