MagnaFlow Performance Series Satin Stainless Steel Oval Muffler - 4x9x11in - 2.25in Inlet/Outlet (11378)
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
This is a universal fit component; please verify body dimensions and exhaust piping diameter for compatibility with your vehicle. The MagnaFlow 11378 Performance Series muffler is engineered to deliver a smooth, deep exhaust tone while optimizing flow for dyno-proven performance. Its free-flowing straight-through design utilizes a perforated stainless steel core wrapped in stainless steel mesh and acoustic fiber fill to manage sound without restricting exhaust velocity.
Constructed from 100% corrosion-resistant stainless steel, the weight-optimized 4x9x11-inch oval body features a clean satin finish suitable for custom builds or OE replacements. The bi-directional, reversible design allows for flexible installation in the orientation that best fits your chassis. This muffler is produced using CNC precision robotic manufacturing to ensure tight tolerances and long-term durability.
