Pacemaker 3" Ceramic Coated Headers & High-Flow Cats for Ford Mustang FN S650 5.0L V8 (2018-2023) - Suits Factory Exhaust - PP4178-59

Pacemaker 3" Ceramic Coated Tuned Length Headers & High-Flow Catalytic Converters for Ford Mustang 6th Generation (2018-2023 5.0L V8 Coyote) - Suits Factory Exhaust System (RHD Only) - PP4178-59

Supercharge your engine's gas scavenging capabilities, drop under-bonnet operating temperatures dramatically, and extract a crisp, high-revving muscle car tone from your engine block with the Pacemaker Performance full 3-inch extractor and catalytic converter package. Meticulously engineered to maximize tracking on the face-lifted 6th Generation Ford Mustang 5.0L Gen 3 Coyote V8 powerplants (347kW dual-fuel injection variants), this premium header kit introduces massive 1-7/8" tuned primary runs wrapped in an advanced thermal barrier coating. Formulated specifically to clear tight steering racks on factory Right-Hand Drive (RHD) configurations, it acts as a direct-fit bolt-up interface that routes into your existing factory intermediate cat-back layout structure. By accelerating exhaust gas velocities out of the cylinder head ports while managing radiant engine-bay heat, this race-bred design optimizes volumetric flow efficiency across the entire DOHC power curve. Complete with high-efficiency metallic high-flow catalytic converters, custom cat extension pipes, and essential plug-and-play oxygen sensor extension looms, it delivers a turnkey structural upgrade that extracts absolute peak performance without requiring custom underbody pipe fabrication.

Note: Fits 6th Generation Ford Mustang variants (FN face-lift series) built from October 2017 through to April 2023 equipped with the 5.0L Coyote V8 engine layout; fits factory Right-Hand Drive (RHD) configurations only across both manual and automatic transmissions. Does not fit early 2015-2017 FM series models or Left-Hand Drive (LHD) vehicle platforms.

Features:

Precision-manufactured in Australia to unlock true high-RPM gas velocity pathways, provide extreme heat shielding under high load conditions, and deliver seamless factory exhaust integration.

• Tuned Long-Tube Header Design: Premium secondary-paired 1-7/8 inch (47.6mm) heavy-duty primary runs configured to achieve precise scavenging pulse timing, dramatically boosting mid-to-high range horsepower tracking.
• Advanced Ceramic Coating: Fully treated with Pacemaker's signature thermal barrier ceramic finish to lock radiant heat inside the tubes, reducing under-bonnet heat soak and protecting critical engine-bay infrastructure.
• High-Flow Metallic Catalytic Converters: Incorporates low-restriction 3" metallic high-flow catalytic converter assemblies to expand volumetric airflow parameters while minimizing backpressure penalty boundaries.
• Factory Cat-Back Adaptability: Engineered with unique Left and Right-Hand side high-flow cat extensions that reduce down flawlessly to mate up with original factory or factory-style aftermarket cat-back exhaust components.
• Right-Hand Drive Optimized Clearance: Specifically bent and path-mapped to clear the standard RHD steering column shaft assembly without rubbing, rattling, or modifying chassis rails.
• Harness Extensions Included: Package comes complete with dual O2 sensor wiring harness extension looms to maintain correct plug-and-play factory engine management connectivity.
• Premium Material Base: Hand-crafted utilizing mandrel-bent heavy-wall tubing alongside precision machined engine exhaust plates to counter flange distortion under extreme temperature cycles.

Vehicle Applications:

Important Fitment Notes:

• Specifically engineered to fit the face-lifted 6th Generation Ford Mustang (FN Series) featuring the upgraded 347kW 5.0L Coyote V8 configuration.
• Right Hand Drive Only: Primary pipe sweeps are custom-mapped strictly to navigate the standard under-bonnet geometry of RHD Australian-market vehicles. It will not fit Left-Hand Drive (LHD) parallel import models due to steering column housing clashes.
• Suit Factory Exhaust: This specific package includes bespoke Left-Hand (CATMUSTL-FE) and Right-Hand (CATMUSTR-FE) high-flow converter extensions that taper down dynamically to line up seamlessly with the factory cat-back exhaust midsection footprint.
• O2 Extension Harnesses Included: Due to the shifted, high-velocity relocation of the premium sports catalytic substrate beds, the kit includes two oxygen sensor wiring extension harnesses to avoid tensioning factory harness segments.
• Installation by an authorized automotive exhaust fabrication expert or high-performance master technician is highly recommended to protect heat shield clear spaces, establish completely gas-tight slip seals, and guarantee proper alignment clearances along the steering shaft.
