Pacemaker 2.5" Cat-Back Performance Exhaust System for Ford Mustang GT S550 Convertible 5.0L V8 2015–2017 - PP4178-02

Pacemaker 2.5" Performance Cat-Back Exhaust System for Ford Mustang GT Convertible (5.0L Coyote V8) - PP4178-02

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 satisfy the structural underbody requirements of the S550 soft-top platform, this premium system is precision-molded to route flawlessly around the specific chassis cross-bracing unique to the factory Ford Mustang Convertible. 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 open-air highway drone typical of convertible layouts. Note: Fits Ford Mustang GT S550 Convertible 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 convertible 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.
• Convertible-Specific Clearances: Custom-tailored pipe bends and bracket positions engineered explicitly to route cleanly around the additional under-car chassis reinforcement bracing unique to the convertible.
• Dual Drive Layout Compatible: Global underbody routing metrics designed to seamlessly 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 open-air cabins 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 Convertible models powered by the 5.0L Coyote V8 engine configuration (2015–2017 models).
• Convertible Specific Chassis Layout: Mustang Convertibles feature extensive cross-bracing under the vehicle center floor pan to maintain structural rigidity. This kit features specific piping bends and modified intermediate paths to completely clear these factory braces without rubbing. It will not align properly with standard Fastback Coupe variants.
• 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 around convertible under-braces, strict alignment, and gas-tight seals under the floor pan.
