£1,467.00
Model Compatibility
- Yamaha YZF-R1 (2004–2006)
- Yamaha YZF-R1 1000 SP (2006)
- Yamaha YZF-R1 50th Anniversary Limited Edition (2006)
Note on Generation Limits: This specific system will not fit the 2007–2008 R1 models because Yamaha changed the subframe routing angles for the 16-valve engine transition, nor will it accommodate the 2009+ crossplane models which feature completely different link-pipe pathways.
Key Performance Specifications
- Road Legality: Fully EC/ECE type-approved and street-legal. It preserves factory emission standards because the basic version allows you to keep the original underbelly catalytic converter block intact.
- Materials: High-grade, handmade carbon-fibre twin outer muffler sleeves paired with distinct hexagonal carbon end caps, lightweight carbon mounting straps, and premium titanium internals.
- Performance Maximisation: Drops internal backpressure to yield a healthy power increase of 4.0 hp (3.0 kW) at 12,800 rpm and adds 9.7 Nm of torque at 6,000 rpm on the dyno.
- Weight Reduction: Significantly lightens the highest point of the machine's tail section, enhancing center-of-gravity dynamics and transitional cornering agility.
- Tuning Requirements: True plug-and-play installation. Because backpressure values map cleanly to stock constraints, no ECU remapping or fuelling tweaks are required to prevent lean engine wear.
- Sound Profile: Emits a distinctly deeper, resonant inline-four growl. It comes packaged with removable noise-reducing baffles (dB killers) secured behind the end caps.
