Product Description

The MBRP S7215409 3" Resonator Bypass X-Pipe is engineered specifically for 2015-2020 Ford Mustang Shelby GT350 and GT350R models equipped with the 5.2L V8 engine. Constructed from T409 stainless steel with mandrel bends, this resonator bypass replaces the restrictive factory mid-section to improve exhaust flow and produce a more aggressive, race-inspired exhaust tone.

Designed for enthusiasts looking to enhance sound and performance without replacing the entire exhaust system, the S7215409 delivers deeper tone and better throttle response. Installation requires cutting the factory exhaust piping before the bolt-on fitment, and the included clamps make integration with OEM and aftermarket cat-back systems straightforward. Backed by MBRP's lifetime warranty, this resonator bypass is a durable upgrade for GT350 and GT350R owners seeking a bold exhaust note.
