Model Compatibility

- Yamaha YZF-R1 World GP 50th Anniversary Edition (2012)
Key Performance Specifications
- Road Legality: Fully EC/ECE type-approved and road-legal (Euro 3 compliance standards are maintained natively when utilizing the original factory underbelly catalytic converter block).
- Materials: High-grade, premium carbon-fibre twin outer muffler sleeves paired with matching handmade carbon-fibre end caps and lightweight carbon mounting clamps.
- Performance Maximisation: Drops internal backpressure to yield an extra 2.4 hp (1.8 kW) at 12,430 rpm and 2.3 Nm of torque at 2,630 rpm.
- Weight Reduction: Saves 1.5 kg over the rear tail section by replacing the heavy, heavily shielded factory original under-seat mufflers.
- Tuning Requirements: True plug-and-play installation. Because backpressure maps cleanly to stock specifications, no ECU remapping or fuelling tweaks are required.
- Sound Regulation: Emits a distinctly deeper, throaty crossplane rumble. It is packaged with removable noise-reducing baffles (dB killers) secured behind the end caps.
Upgrade Options & Accessories
- Full System Conversion Link Pipes: If you later wish to bypass the heavy original cat box and upgrade this street slip-on layout into a full race-style configuration, these canisters can be paired directly with the Akrapovič Optional Titanium Link Pipe (Part Number: L-Y10SO9L) or the Y-pipe collector. (Note: Doing so removes the catalyst and voids its road-legal status).
