953-203-103
Overview:
The Weapon R Exhaust S-Pipe is a high-performance component designed specifically for the 2008–2015 Scion xB. This S-pipe is part of Weapon R’s race-oriented exhaust solutions, engineered to enhance exhaust flow and support increased power output. Ideal for enthusiasts focused on racing or high-RPM performance, this S-pipe helps optimize your vehicle’s exhaust system when paired with other Weapon R components.
Built for drivers who demand improved torque and horsepower gains, especially those running camshafts and operating in a high-revving environment, this S-pipe is a critical piece for maximizing your Scion xB’s race header setup.
Key Features:
This Weapon R S-pipe offers several technical advantages that contribute to its performance benefits:
- Designed as part of a 4-2-1 race header system with long primary tubes to enhance high RPM power delivery.
- Stepped tubing sizes optimize exhaust velocity and torque across the rev range.
- Features a 2.5" collector to maximize exhaust flow and reduce backpressure for better performance gains.
- Eliminates the catalytic converter to allow unrestricted exhaust flow, ideal for race applications.
- Constructed to complement vehicles equipped with performance cams and designed for high RPM operation.
- Precision-engineered for the Scion xB chassis to ensure proper fitment and function within the exhaust system.
Construction & Design:
The Weapon R Exhaust S-Pipe is crafted with performance and durability in mind. Its design incorporates long primary tubes and stepped tubing diameters to balance torque and horsepower effectively. The 2.5-inch collector enhances exhaust scavenging, which improves overall engine efficiency at high RPMs.
By removing the catalytic converter, this S-pipe reduces exhaust restrictions, allowing your engine to breathe more freely and respond better under racing conditions. The construction quality ensures reliable operation during demanding track or race use.
Installation & Fitment:
This S-pipe is designed specifically for the 2008–2015 Scion xB and integrates seamlessly with Weapon R’s 4-2-1 race header system. It is intended for use in race or track applications where the catalytic converter is removed.
Installation requires compatibility with the corresponding Weapon R headers and may involve modifications typical of race exhaust setups. Please note this product is sold as-is and was previously used as a display piece at shows.
