The Pro Circuit T-4 Exhaust System, manufacturer part number 4H06150 and vendor part number 4H06150, is a tunable performance exhaust designed for Honda CRF150F models. This system provides a practical alternative to the more specialized Pro Circuit Ti-4R System while delivering focused exhaust performance and a refined sound profile for trail and recreational riding applications.
The head pipe incorporates an RC-4 Resonance Chamber to help reduce exhaust noise while maintaining the functional advantages of the T-4 design. Depending on the motorcycle model year, the RC-4 Resonance Chamber may not be included with the system. Verify the configuration for your specific application before installation. The system is engineered for fitment on 2006, 2007, 2008, 2009, and 2012–2017 Honda CRF150F motorcycles.
Built by Pro Circuit, this exhaust system is intended for riders seeking a purpose-designed replacement or upgrade for the original CRF150F exhaust. Its model-specific design supports proper installation on compatible Honda motorcycles. Professional installation or reference to the manufacturer’s installation instructions is recommended to ensure correct mounting, clearance, and exhaust sealing.
