The MagnaFlow 6in. Round Straight-Through Performance Exhaust Muffler 12646 brings our world-famous exhaust sound and dyno-proven performance to your ride in a weight-optimized 6x6x18in. package with a premium satin finish. The straight-through free-flowing design of this round-bodied muffler's reversible, universal 2.5/2.5in. diameter inlet/outlet layout enables versatile installation options to match the spacing requirements of your vehicle. Due to the cutting and welding involved, professional installation is highly recommended. Internally, 12646 utilizes a perforated stainless steel core wrapped in stainless steel mesh and acoustic fiber fill to achieve a powerful, resonant tone. This muffler is made of durable, corrosion resistant stainless steel and produced using cutting-edge CNC precision robotic manufacturing techniques, all backed by MagnaFlow's limited lifetime construction warranty.

Timothy M. ★★★★★

Installed it on my truck last weekend and the dyno-proven performance claims are no joke—definitely feels like I picked up some horsepower. The 6x18 inch round straight-through design gives it a deep, aggressive tone without being obnoxiously loud on the highway.

Lily ★★★★★

The 18-inch length fit perfectly into my custom exhaust setup, and the straight-through design gave it that deep, aggressive tone I was after without being obnoxious on the highway. Weight is noticeably less than the stock muffler too.

Natalie ★★★★★

Installed this on my truck last weekend and the deep, mellow tone at idle is exactly what I was hoping for. The straight-through design really opens up when you step on it without being obnoxious on the highway.
