Specifically engineered to maximize scavenging efficiency and enhance the distinct mid-to-high RPM acoustics of the iconic 5.0L Coyote V8, this premium system is precision-molded to clear the floor pan lines, underbody layout, and multi-link independent rear suspension geometry of the S550 Fastback platform. By replacing your stock, restrictive factory piping with a high-flow mandrel-bent performance construction downstream of the catalytic converters, it optimizes gas velocity to clear spent exhaust out rapidly and completely eliminate power-robbing backpressure under acceleration. As Australia’s premium exhaust innovator, Pacemaker pairs this high-flow path with patented V-Tex technology and signature double-skinned mufflers to deliver a raw, thumping muscle car sound outside while actively engineering out harsh, intrusive interior cabin boom or high-load highway drone. \u003cem style=\"color: #222222 !important;\"\u003eNote: Fits Ford Mustang GT S550 Fastback Coupe models (2015–2017) equipped with the 5.0L Coyote V8 engine configuration;
