MagnaFlow 14226 Straight-Through Performance Exhaust Muffler 2.5in Offset/Center 5x8x14 Oval Stainless

The MagnaFlow 14226 is a straight-through performance exhaust muffler built around a 5x8-inch oval body with a 2.5-inch offset inlet and 2.5-inch center outlet. Constructed entirely from corrosion-resistant stainless steel and manufactured using CNC precision robotic techniques, this muffler delivers long-lasting durability and a premium brushed exterior finish.

At its core, the 14226 uses a free-flowing straight-through perforated stainless steel tube wrapped in stainless steel mesh and two-stage acoustical fiber fill. This architecture minimizes exhaust restriction and back pressure while controlling unwanted drone, producing the classic deep, resonating exhaust tone that MagnaFlow performance mufflers are known for. Dyno testing validates real-world performance gains through improved exhaust flow dynamics and gas evacuation.
