Pacemaker Twin 2.5" Performance Exhaust System with Headers for Ford Mustang GT S550 Convertible 5.0L V8 2015–2017 RHD - PP4178-04

Pacemaker Full Twin 2.5" Performance Exhaust System with Headers & Hi-Flow Cats for Ford Mustang GT Convertible (5.0L Coyote V8) - PP4178-04

Unleash an uncompromised, aggressive American muscle roar and unlock substantial power gains from your high-revving quad-cam engine with the Pacemaker Sport Systems complete twin 2.5-inch performance exhaust solution. Specifically engineered to maximize scavenging efficiency, optimize exhaust gas velocity, and satisfy the unique chassis configurations of the iconic S550 platform, this premium system is precisely shaped to map the specific structural underbody bracing lines of the factory Ford Mustang Convertible. By upgrading your stock layout to race-proven performance extractors paired with mandrel-bent twin 2.5" plumbing and high-flow metallic catalytic converters, it maximizes exhaust gas scavenging to completely eliminate power-robbing backpressure under heavy acceleration. As Australia’s premium exhaust innovator, Pacemaker integrates elite structural engineering with patented V-Tex technology and signature double-skinned mufflers, delivering a commanding, throaty performance bark on throttle while actively engineering out harsh, intrusive cabin boom or highway drone typical of convertible cabins. Note: Fits Right-Hand Drive (RHD) Ford Mustang GT Convertible models (2015–2017) equipped with the 5.0L Coyote V8 engine configuration; does not fit Fastback models due to convertible-specific chassis reinforcement paths.

Features:

Precision-manufactured in Australia to deliver a high-velocity flow upgrade, maximum structural longevity under intense heat, and a refined muscle car acoustic profile for the iconic RHD Mustang platform.

• Complete Headers & Full System: Comprehensive track-and-street performance solution incorporating high-flow primary headers, 3" metallic high-flow catalytic converters, and a matching twin 2.5-inch performance cat-back system.
• Convertible-Specific Clearances: Custom engineered to route flawlessly around the additional under-car chassis strengthening cross-bracing unique to the soft-top convertible floor pan lines.
• Premium Materials: Constructed completely from durable, heavy-gauge Exhaust Grade 409 Stainless Steel to ensure superior resistance to thermal fatigue and rust.
• Mandrel Bent Tubing: Rigid twin 2.5" (63.5mm) pipe structure guarantees a smooth, uniform internal diameter through all bends to optimize exhaust gas tracking.
• V-Tex Technology: Advanced internal patented anti-drone configuration cancels out harsh, low-frequency cabin resonance typical of open-air convertibles without restricting gas velocity.
• Signature Mufflers: Heavy-duty double-skinned 409 Stainless Steel mufflers offer premium case reinforcement, preventing case distortion and internal packing blowout under extreme load.
• Right-Hand Drive Optimized: Specifically mapped and cleared to fit Right-Hand Drive (RHD) configurations seamlessly around steering linkages and factory layout components.

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 Layout Constraints: 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 or floor vibration. It will not align properly with standard Fastback variants.
• Right-Hand Drive Only: Header primary routing is exclusively mapped to navigate around standard factory RHD steering gear configurations. Will not fit imported Left-Hand Drive (LHD) models.
• Full kit scope: Comprehensive track-and-street performance solution from engine block to rear exit, including tuned primary headers, high-flow metallic catalytic converters, intermediate twin 2.5" tubing, and signature double-skinned rear twin mufflers.
• Professional automotive performance technician installation is highly recommended to guarantee ideal ground clearance around convertible bracing, correct steering link alignment, and strict gas-tight seals.
