DescriptionThe whole story▼
For riders who spend their weekends at the track and want an exhaust system that earns its keep every session, the Arrow Pro-Race Slip-On 71179HCP delivers a full titanium construction across every component — silencer body, end cap, mid-pipe and internals — keeping the weight down to just 2.21 kg and throttle response sharper from the first corner. Combined with the catalyst replacement pipe, this kit removes a known restriction in the YZF-R1 and R1M exhaust path, making it one of the most straightforward performance upgrades available for the 2017-2026 generation.
Key Features
- Full titanium construction throughout — silencer, end cap, mid-pipe and internal components — for outstanding durability at minimal weight.
- Weighs just 2.21 kg, reducing unsprung and overall mass for improved handling and acceleration response.
- 68 mm outlet and 53 mm inlet diameters engineered for maximum flow and optimised power delivery across the rev range.
- 250 mm silencer length strikes a balance between compact fitment and acoustic tuning on track.
- Includes a db-killer insert for compliance with circuit noise regulations during race weekends.
- Can be paired with an Arrow header to build a complete Arrow full system, unlocking further performance gains.
Performance and Build Quality
Arrow's Pro-Race range is built without compromise for circuit use. Every component in this kit — including the mid-pipe that replaces the original catalyst — is fabricated from titanium, a material chosen for its exceptional strength-to-weight ratio and resistance to the sustained high temperatures generated during hard track use. Unlike stainless steel alternatives, titanium stays cooler to the touch and resists discolouration over repeated heat cycles, keeping the silencer looking purposeful even after a full race season.
The 53 mm inlet mates directly to the stock header collector on the YZF-R1 and R1M, making fitment straightforward with no fabrication required. The 68 mm outlet, combined with the catalyst replacement pipe, significantly reduces back-pressure in the exhaust path, which translates into more responsive throttle pick-up and a freer-revving character — qualities that matter most on a track like the R1 demands.
Road ECU Remapping Recommendation
Because this kit alters exhaust flow characteristics substantially, Arrow and Inter-Pace strongly recommend a full ECU remap after installation. Remapping the fuel injection and ignition maps to suit the new exhaust will ensure the engine runs correctly throughout the rev range and that the power gains from the freer-flowing system are fully realised. Without a remap, the factory fuelling may run lean at certain throttle positions.
Race Use Notice
The Arrow Pro-Race Slip-On 71179HCP is designed and approved for closed-circuit competition use only. It does not carry road-use homologation and must not be used on public roads. The included db-killer insert addresses circuit noise limits — always check individual venue regulations before fitting or removing it.
