Overview:
Weapon R Stainless Steel Race Headers are precision-engineered exhaust components designed to unlock the full performance potential of your Toyota 86, Subaru BRZ, or Scion FR-S. Crafted for serious enthusiasts and racers, these headers deliver significant gains in horsepower and torque while improving throttle response and exhaust sound. Whether you’re building a high-performance street car or a dedicated race vehicle, these headers provide the power and responsiveness needed to elevate your driving experience.
Ideal for drivers who push their engines to the limit, Weapon R’s race headers offer a lightweight, durable solution that enhances acceleration and overall engine efficiency.
Key Features:
These race headers incorporate advanced design and construction techniques to maximize performance and reliability:
- CAD-Simulated Design: Developed using computer-aided design and flow testing to ensure optimal exhaust flow and efficiency.
- Long Primary Tubes: Engineered to boost high-RPM power for stronger acceleration and top-end performance.
- Stepped Sizing: Optimizes torque delivery across a broad RPM range, enhancing drivability and power consistency.
- Race Merge Collector: Provides unrestricted exhaust flow to maximize horsepower gains and reduce back pressure.
- Catalytic Converter-Free: Designed for race applications to maximize power output without the restrictions of catalytic converters.
- Lightweight Stainless Steel Construction: Improves vehicle handling by reducing overall weight while resisting corrosion and heat.
Construction & Design:
Weapon R race headers are constructed from high-quality stainless steel, ensuring durability and resistance to corrosion under extreme conditions. The headers feature long primary tubes with stepped sizing, carefully designed to balance exhaust velocity and volume for improved engine breathing. The race merge collector design enhances exhaust scavenging, which contributes to increased horsepower and torque. The entire system is engineered with precision TIG welding and mandrel bends to maintain consistent flow and fitment.
Performance & Sound
These headers deliver noticeable improvements in engine output and responsiveness. By eliminating the catalytic converter and optimizing exhaust flow, you’ll experience increased horsepower and torque, especially at higher RPMs. The improved exhaust scavenging also sharpens throttle response, making acceleration more immediate and aggressive. Additionally, the headers produce a deeper, more throaty exhaust note that enhances the auditory experience of your performance build.
Installation & Fitment:
Designed specifically for the following vehicles, these headers offer a direct bolt-on fitment using factory mounting points:
- 2017–2020 Toyota 86
- 2013–2020 Subaru BRZ
- 2013–2016 Scion FR-S
No cutting, drilling, or special tuning is required for installation, making these headers a straightforward upgrade for race and high-performance builds.
