The MagnaFlow 5" X 11" Oval Straight-Through 12588 is engineered to enhance your ride with a healthy helping of our signature exhaust sound and dyno-proven performance thanks to its free-flowing straight-through perforated stainless steel core wrapped in stainless steel mesh and acoustic fiber fill. The reversible, universal 3/2.5in. diameter inlet/outlet Straight-Through layout allows you to install it in whatever orientation and configuration you see fit. However, professional installation is highly recommended. Muffler 12588's weight-optimized 5x11x22in. oval-shaped body features a satin finish that elevates the overall aesthetics of your current exhaust setup. 12588 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.
