SC-Project GP70-R Slip-On Silencer + Catalyst Replacement Pipe Kawasaki ZX-10R/RR (2016-2020) K22A-DET70

The SC-Project GP70-R is a genuine MotoGP-derived slip-on silencer that transforms your Kawasaki ZX-10R or ZX-10RR into a sharper, lighter, and noticeably more potent track tool — without the complexity or cost of a full system swap. Built entirely from titanium with a carbon heat shield and a laser-engraved SC-Project logo, this kit represents outstanding value for trackday regulars who want measurable performance gains and a race-quality finish.

Key Features

• Titanium construction throughout: carbon silencer body with titanium end cap keeps unsprung and overall mass to an absolute minimum, shedding 5.1 kg versus the stock exhaust (SC: 1.3 kg vs. OEM: 6.4 kg)
• Proven power gains: +13.8 hp at 9,000 rpm and +10.8 Nm torque at 6,750 rpm, measured on the Kawasaki ZX-10R with this exact kit fitted
• CNC-machined titanium coupling sleeves ensure a precise, rattle-free fit to the OEM header every time
• T.I.G.-welded titanium joints for maximum structural integrity and a clean, professional finish that lasts season after season
• Full-titanium pipe fitting with variable taper (Ø60 mm – Ø70 mm) optimises exhaust flow and contributes directly to the power figures above
• Integrated carbon heat shield manages thermal output and adds the unmistakable racing aesthetic that sets this system apart

Performance and Sound

Stripping 5.1 kg from the tail of your ZX-10R has an immediate and tangible effect on handling: turn-in sharpens, the bike feels more responsive to body input, and the power delivery through the mid-range gains the urgency that trackday riding demands. The gains of +13.8 hp and +10.8 Nm are not peak-only figures — the optimised exhaust flow from the variable-taper titanium pipe fitting broadens the usable powerband across the rev range.

At the loud end, the GP70-R produces 118 dB at 6,500 rpm without a dB killer. This is an uncompromised racing note — raw, authoritative, and immediately recognisable as SC-Project. It is not road-legal and is designed exclusively for closed-circuit use.

Construction and Materials

SC-Project manufacture the GP70-R to the same standards demanded by their WorldSBK and MotoGP programmes. The carbon silencer body is paired with a titanium end cap, keeping weight at 1.3 kg for the complete unit. CNC-machined titanium coupling sleeves locate the silencer precisely on the OEM collector stub, while T.I.G. welding is used throughout the titanium pipe fitting and mounting hardware for both strength and visual refinement. The integrated carbon heat shield handles the extreme temperatures generated in racing conditions, protecting both the rider and adjacent components.

Fitment and Compatibility

This kit is a direct-fit slip-on replacement for the following models:

• Kawasaki ZX-10R (2016–2020)
• Kawasaki ZX-10RR (2016–2020)

The full-titanium pipe fitting with variable taper (Ø60 mm – Ø70 mm) accommodates the OEM header outlet without modification. Mounting springs and bolts are included for a straightforward installation.

Important Notice

This exhaust system is not road-legal and is designed exclusively for closed-circuit, competition, and trackday use. It must not be used on public roads. Part number for the titanium version: K22A-DET70T.
