Pacemaker Performance Turbo-Back Exhaust System for Ford Mustang S550 Fastback Coupe 2.3L EcoBoost 2015–2017 - PP4173-01

Pacemaker Full Performance Turbo-Back Exhaust System for Ford Mustang S550 Fastback Coupe (2.3L EcoBoost Turbo I4) - PP4173-01

Accelerate turbo spool response, maximize high-boost airflow efficiency, and transform the acoustic character of your forced-induction powerplant with the Pacemaker Sport Systems heavy-duty complete turbo-back performance exhaust solution. Precision-engineered specifically to handle the thermal loads and high gas velocity demands of the 2.3L EcoBoost twin-scroll turbocharged engine, this premium full system upgrades your vehicle path directly from the turbocharger turbine outlet back to the rear exhaust tips. Mapped carefully to clear the sleek fastback coupe floor pan lines, transmission tunnel paths, and multi-link independent rear suspension geometry, it guarantees an uncompromised, rub-free layout configuration beneath your fixed-roof performance platform. By pairing a high-flow downpipe layout and a premium 3" metallic high-flow catalytic converter with smooth, mandrel-bent performance plumbing, it completely obliterates backpressure to minimize turbo lag and deliver rapid boost progression. As Australia’s premium exhaust innovator, Pacemaker pairs this free-flowing system with patented V-Tex technology and signature double-skinned mufflers to emit a deep, commanding sports car tone under load while actively filtering out harsh, low-frequency highway drone or cabin resonance. Note: Fits Ford Mustang S550 Fastback Coupe models (2015–2017) equipped with the 2.3L EcoBoost Turbo 4-cylinder engine configuration; does not fit Convertible variants due to the altered floor paths required to clear soft-top chassis reinforcement cross-bracing.

Features:

Precision-manufactured in Australia to deliver a definitive performance upgrade, rapid boost acceleration, and an aggressive, drone-free turbo sports acoustic profile for the iconic S550 fastback coupe platform.

• True Turbo-Back System: Comprehensive, high-performance exhaust solution from the turbocharger dump housing down to the rear dual exit tips, including a premium high-flow converter setup.
• Fastback Coupe Optimized: Custom-engineered to clear the floor pan configurations, standard chassis tunnels, and factory hanger geometries unique to the fixed-roof fastback platform.
• High-Flow Catalyst Integration: Includes a high-flow 3" metallic catalytic converter section designed to optimize eco-compliance metrics while maximizing high-volume gas velocity out of the turbine.
• Premium Materials: Constructed completely from durable, heavy-gauge Exhaust Grade 409 Stainless Steel to ensure superior structural longevity under intense forced-induction thermal stress.
• Mandrel Bent Tubing: Rigid plumbing structure guarantees a smooth, uniform internal pipe diameter through all bends to eliminate gas turbulence and prevent restriction.
• V-Tex Technology: Advanced internal patented anti-drone configuration filters out harsh, raspy 4-cylinder cabin resonance typical of turbo sports cars without restricting system backpressure.
• Signature Mufflers: Heavy-duty double-skinned 409 Stainless Steel mufflers offer premium outer case reinforcement, preventing case distortion and internal packing blowout under intense high-boost heat.

Important Fitment Notes:

• Specifically engineered to fit Ford Mustang S550 Fastback Coupe models powered by the 2.3L EcoBoost inline-4 turbocharged engine configuration (2015–2017 models).
• Coupe Specific Layout: This system features specific piping clearances and bracket mapping designed precisely to mount under the fastback coupe chassis path. It will not adapt cleanly to Convertible variants because it does not feature the necessary underbody relief routes to clear the additional soft-top chassis reinforcement cross-braces.
• Full kit scope: Comprehensive high-efficiency solution from turbocharger turbine collector face to rear bumper line, including performance dump pipe/downpipe plumbing, high-flow metallic converter section, intermediate structural routing lines, and dual-exit signature double-skinned rear mufflers.
• Direct bolt-on layout matches vehicle-specific factory rubber hanger positions and turbocharger exit flange mounts. No custom fabrication or welding mapping required.
• Professional automotive performance technician installation is highly recommended to guarantee ideal ground clearance, verify turbo flange scaling, and secure strict gas-tight seals.
