Specifically engineered to maximize scavenging efficiency and satisfy the high-velocity gas volume demands of the iconic 5.0L Coyote V8, this premium system is precision-molded to clear the specific underbody bracing lines and structural layouts unique to the S550 soft-top architecture. By replacing your stock, restrictive factory plumbing with a high-volume 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 open-air highway drone typical of convertible cabins. \u003cem style=\"color: #222222 !important;\"\u003eNote: Fits Ford Mustang GT S550 Convertible models (2015–2017) equipped with the 5.0L Coyote V8 engine configuration;
