Muffler, Delta Flow 40 Series, 2 1/4 in. Inlet/2 1/4 in. Outlet, Stainless Steel, Black, Each

Flowmaster Super 40 Series Delta Flow mufflers go a step beyond their original 40 Series product. By precisely placing three internal baffles in the case, and welding them to exacting specifications, the 40 Series Delta Flow mufflers not only out-scavenge the originals, but they also provide superior reductions in exterior sound levels and resonance, which are transmitted through the exhaust system and into the vehicle. You get all this, plus improved torque and horsepower—and that famous Flowmaster sound!
