Product Description

The CORSA Performance 14347 3.0" Double X-Pipe is engineered exclusively for 2015-2020 Shelby GT350 and GT350R Mustangs with the 5.2L V8. Featuring dual crossover points, this X-pipe dramatically improves exhaust scavenging - boosting flow by about 30% - while delivering a deeper, more aggressive tone under throttle.

Crafted from 304 stainless steel with mandrel-bent precision, this bolt-on upgrade replaces the factory H-pipe, fitting seamlessly with OE cat sections. The cut-and-clamp installation makes for a clean, no-weld install and retains full emissions compliance. The upgrade includes clamps and detailed instructions, and carries a limited lifetime warranty.

Fitment is verified through 2020; compatibility with post-2020 models is unconfirmed and not advised. Not CARB-certified for California use. Ideal for GT350 owners seeking refined tone, improved flow, and enhanced performance in a plug-and-play solution.
