About MagnaFlow Performance Mufflers

MagnaFlow Performance mufflers are engineered to deliver a smooth, deep exhaust tone while maintaining a free-flowing exhaust path. Their straight-through perforated stainless steel core, stainless mesh wrap, and acoustical fiber packing help control exhaust sound without the restrictions of traditional chambered designs. This construction provides MagnaFlow's signature performance exhaust character for street-driven vehicles, custom exhaust systems, and performance applications.

Constructed from corrosion-resistant stainless steel, MagnaFlow Performance mufflers feature lap-jointed and welded contact points for structural durability and resistance to seam distortion. Their acoustical packing is designed to maintain consistent sound characteristics throughout the muffler's service life.

Part 12909 features a 3.5-inch center inlet, 3.5-inch offset outlet, and reversible construction for additional installation flexibility. Its large 22-inch oval body, 11 x 5-inch case dimensions, and 28-inch overall length make it suitable for compatible custom exhaust fabrication, larger-diameter exhaust systems, and replacement muffler applications requiring 3.5-inch connections.
