DescriptionThe whole story▼
Arrow's Race-Tech lineage represents decades of Italian exhaust craft distilled into a single silencer, and the 71855PK for the Suzuki GSX-R 1000 is one of its finest expressions. The titanium canister develops a rich heat-blued patina over time — a finish that is earned, not painted — while the carbon end cap anchors the look with a purposeful, race-bred aesthetic that flatters the GSX-R's sharply sculpted tail section.
Key Features
- Full titanium silencer body weighing just 2.23 kg — a genuine reduction that sharpens throttle response and improves handling balance through reduced unsprung mass at the tail.
- Carbon fibre end cap delivers both visual drama and additional heat resistance, complementing the titanium canister perfectly.
- Stainless steel internals and mid-pipe ensure long-term durability and consistent back-pressure characteristics across the rev range.
- 54 mm inlet and 50 mm outlet diameters are engineered to pair with the GSX-R 1000's stock header geometry for an immediate bolt-on fit.
- Includes a removable dB killer for road-legal compliance — extract it for track days to hear the Race-Tech's full voice.
- Carries an E-number type approval, making it fully road-legal across EU markets without the need for an MOT exemption or modification notice.
- Designed to expand into a full system: pair with an Arrow header to unlock the complete performance potential of the exhaust package.
Design, Finish and Heritage
Arrow has been shaping the sound and performance of Italian racing since the 1970s, supplying factory teams across MotoGP, World Superbike and beyond. The Race-Tech series carries that heritage directly to the road. On the GSX-R 1000, the 71855PK canister sits flush with the bodywork at 300 mm in length — compact enough to maintain the bike's aggressive silhouette, substantial enough to produce the deep, progressive note that defines the Arrow sound.
Titanium is not merely a weight-saving material choice here; it is a design statement. Unlike stainless steel or aluminium canisters, a titanium tube develops its own unique heat-tint character over the first few heat cycles — blues, purples and golds appearing at the weld zones and body flanks. No two silencers age identically, which means the 71855PK becomes more distinctively yours the more it is ridden. The carbon end cap, by contrast, stays consistent — matte-weave precision that ties directly to the GSX-R's own carbon trim options.
Performance and Road Use
At 2.23 kg the Race-Tech titanium is substantially lighter than the stock unit, and that mass reduction translates directly into improved throttle response and a more precise, communicative ride at corner entry. The stainless steel mid-pipe and internal components maintain structural integrity through sustained high temperatures, whether commuting or pressing on during weekend runs. For riders already running an Arrow header, combining the two components into a full system brings the most significant gains — Arrow's own mapping recommendation ensures fuelling is calibrated to take full advantage of the revised exhaust flow.
Fitment and Compatibility
The Arrow 71855PK is engineered specifically for the Suzuki GSX-R 1000 produced between 2017 and 2023. It is a direct slip-on replacement requiring no permanent modification to the stock mid-pipe or frame. A custom Arrow mapping is recommended when fitting this silencer to optimise fuel delivery and realise the full performance benefit.
