SC-Project RACE CR-T Full Exhaust System Yamaha YZF-R7 (2021-2025) Y36A-CDE36

The SC-Project RACE CR-T is a full exhaust system built without compromise for track use on the Yamaha YZF-R7 (2021-2025). Developed with the same race-bred philosophy behind SC-Project's MotoGP programmes, this 2-in-1 system strips away every gram of excess weight and every restriction that stands between you and a faster lap time.

Key Features

• Proven power gains of +2.8 hp at 9,000 rpm and +2.8 Nm of torque at 5,250 rpm over the standard system
• Weight saving of 5.2 kg — the SC-Project system weighs just 2.5 kg versus 7.7 kg stock — improving chassis balance and agility immediately
• Full header and silencer constructed from AISI 304 stainless steel for extreme heat resistance and long-term durability under race conditions
• CNC-machined titanium bushings throughout for precise, rattle-free fitment and optimised exhaust flow
• T.I.G.-welded stainless steel and titanium joints for race-grade structural integrity
• Catalyst-free design reduces operating temperature and eliminates the back-pressure that limits peak power
• Available with your choice of titanium silencer (Y36A-CDE36T) or carbon fibre silencer (Y36A-CDE36C) to suit your build

Race Performance

Removing the OEM catalyst fundamentally changes how the YZF-R7 breathes. Exhaust gases exit faster and cooler, which translates directly into sharper throttle response, stronger mid-range pull from 5,250 rpm and a noticeable surge towards the 9,000 rpm power peak. The 5.2 kg reduction in unsprung and rotational mass makes the R7 feel lighter on turn-in and more responsive under braking — exactly what a circuit demands.

At 108 dB at 4,375 rpm, the CR-T produces a raw, deep racing exhaust note with no db-killer fitted. The titanium flame mesh at the silencer outlet is not merely cosmetic — it is a structural element that contributes to the sound character while maintaining the integrity of the end cap at sustained high rpm.

Build Quality & Materials

SC-Project's CR-T sits at the top of their racing catalogue and the material specification reflects that. The primary pipe and collector are fabricated from AISI 304 stainless steel — a grade chosen for its ability to withstand the thermal cycling of continuous track use without warping or cracking. Every joint is T.I.G.-welded and dressed to a consistent finish. The silencer canister is offered in either hand-laid carbon fibre or formed titanium, each delivering the weight reduction and aesthetics that serious race builds require. Metal-shielded springs handle the collector-to-silencer connection and are rated for repeated removal and refitting during race weekends.

Fitment & Compatibility

This system is designed and manufactured exclusively for the Yamaha YZF-R7, covering model years 2021 through to 2025. No adapters or modifications are required — the system bolts directly to the OEM mounting points using the supplied hardware.
