Pacemaker King Brown | 2.5" Exhaust, Headers & Cat | Nissan Patrol GQ Wagon 4.2L EFI | KB9505-HCMX
Pacemaker King Brown Single 2.5" Exhaust with Headers & Catalytic Converter - Nissan Patrol GQ Wagon 4.2L EFI (1987-1997) - KB9505-HCMX
Completely transform the performance and sound of your classic Nissan Patrol GQ with this ultimate Engine-Back King Brown Exhaust System. specifically engineered for the GQ Long Wheel Base (LWB) Wagon fitted with the reliable 4.2L Fuel Injected Petrol (TB42E) engine, manufactured between 1987 and 1997. This comprehensive Single 2 1/2" (2.5 inch) kit is a true end-to-end performance solution, including high-flowing performance headers (extractors) and a high-flow catalytic converter. By scavenging exhaust gases directly from the cylinder head and routing them through an unrestrictive 2.5-inch mandrel-bent system, you will unlock significant gains in horsepower, improved low-end torque for off-roading, and a crisp, deep petrol 6-cylinder exhaust note. Constructed entirely from heavy-duty 409-grade stainless steel, this exhaust system offers extreme durability and immense resistance to rust—perfect for touring and harsh Australian conditions. Proudly Australian Made. Note: Please confirm your vehicle is an EFI equipped 4.2L Petrol GQ Wagon before ordering, as this will not fit Carbureted or Diesel variants.
Features:
A full engine-back replacement engineered for maximum unrestrictive flow, complete compliance, and a commanding exhaust note.
- System Configuration: Complete Single 2 1/2" (2.5 inch) engine-back exhaust system.
- Included Components: Comes complete with tuned-length performance headers (extractors) and a high-flow stainless steel catalytic converter.
- Material: Tough 409 grade stainless steel construction for excellent corrosion resistance and formidable longevity in extreme outback environments.
- Manufacturing: 100% Australian Made for harsh, demanding Australian off-road conditions.
- Performance: Mandrel-bent 2.5-inch piping and high-flow extractors allow the TB42E engine to breathe freely, yielding distinctly improved throttle response, greater low-end pulling power, and enhanced fuel efficiency.
- Sound: Delivers a deep, pronounced petrol 6-cylinder exhaust note without excessive cabin drone.
- Fitment: Designed to utilize existing factory mounting points where possible for a straightforward fitment.
