Product Description

The MBRP S7213409 2.5" Resonator Bypass X-Pipe is engineered for Ford Mustang GT variants equipped with the 5.0L Coyote V8 from 2015 through 2025. Constructed from durable T409 stainless steel with mandrel bends for improved exhaust flow, this resonator bypass replaces the restrictive stock resonator mid-section to produce a deeper, more aggressive exhaust tone and enhanced engine sound.

Designed to integrate with OEM and most aftermarket cat-back systems, the S7213409 helps reduce backpressure and improve throttle response while retaining the factory exhaust layout. Installation requires cutting the factory resonator section, and the included clamps allow a secure connection to existing piping. Ideal for Mustang owners seeking a more visceral exhaust note and improved performance without replacing the entire exhaust system.
