Description

The MagnaFlow 6in. Round Straight-Through Performance Exhaust Muffler 12649 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 3/3in. 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, 12649 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.
