Description

The Magnaflow 14156 is a 4-inch round performance muffler from the Race Series. It features a straight-through design to reduce back pressure and increase exhaust flow, providing enhanced performance and an aggressive exhaust note suitable for racing and off-road applications. Constructed from corrosion-resistant T-409 stainless steel with a mirror-like polished finish, it also includes stainless steel mesh and high-temperature acoustic suppression material to manage sound.
