Pacemaker 2.5" Performance Cat-Back Exhaust System for Ford Mustang GT Coupe (5.0L Coyote V8) - PP4178-01
Unleash a deep, aggressive American muscle growl and optimize gas flow velocity from your high-revving quad-cam engine with the Pacemaker Sport Systems heavy-duty 2.5" performance cat-back exhaust solution. 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. Note: Fits Ford Mustang GT S550 Fastback Coupe models (2015–2017) equipped with the 5.0L Coyote V8 engine configuration; engineered to suit both Left-Hand Drive (LHD) and Right-Hand Drive (RHD) configurations.
Features:
Precision-manufactured in Australia to deliver a premium flow upgrade, exceptional structural durability under high heat, and a refined performance acoustic profile for the global Mustang GT platform.
- True Cat-Back Section: Complete performance intermediate plumbing and rear muffler layout engineered to bolt up securely behind your factory or high-flow catalytic converters.
- Dual Drive Layout Compatible: Precision-cleared underbody routing architecture engineered explicitly to accommodate both Left-Hand Drive (LHD) and Right-Hand Drive (RHD) chassis variations.
- Premium Materials: Constructed completely from durable, heavy-gauge Exhaust Grade 409 Stainless Steel to ensure superior structural longevity under intense thermal stress.
- Mandrel Bent Tubing: Rigid 2.5" (63.5mm) pipe structure guarantees a smooth, uniform internal diameter through all bends to optimize exhaust gas velocity and prevent restriction.
- V-Tex Technology: Advanced internal anti-drone configuration filters out harsh, low-frequency cabin resonance typical of sports coupes without creating any power-robbing flow restrictions.
- Signature Mufflers: Heavy-duty double-skinned 409 Stainless Steel mufflers offer premium outer case protection, zero internal packing blowout under high thermal stress, and precise tonal control.
- Direct Bolt-On Layout: Engineered as a comprehensive, vehicle-specific full bolt-up kit that mounts directly onto existing factory rubber hanger positions—no custom fabrication required.

Important Fitment Notes:
- Specifically engineered to fit Ford Mustang S550 GT Fastback Coupe platforms powered by the 5.0L Coyote V8 engine configuration (2015–2017 models).
- Coupe Specific Chassis Layout: This configuration features tailor-formed exhaust pipe paths and bracket placements designed precisely to mount cleanly under the standard fastback coupe floor pan lines. It will not adapt correctly to Convertible models due to structural under-car cross bracing on the soft-top platforms.
- Global Steering Compatibility: Underbody routing clearance metrics are optimized to seamlessly accommodate both Left-Hand Drive (LHD) and Right-Hand Drive (RHD) export market models.
- Full kit scope: Comprehensive high-flow cat-back line including performance intermediate plumbing sections and a signature double-skinned rear muffler assembly with polished tips.
- Direct bolt-on design reuses your vehicle's factory rubber hanger positions and standard catalytic converter paths. No custom fabrication or welding layout mapping is required.
- Professional automotive performance technician installation is highly recommended to guarantee ideal ground clearance, strict alignment, and gas-tight seals under the floor pan.
