CR-T Exhaust by SC-Project

Motovation is the leading team of product experts for SC-Project products.

Here is what our staff has to say about this Yamaha R1 exhaust.

• Significant weight reduction for the Yamaha R1: The CR-T system claims a dramatic drop in weight compared to stock — roughly going from ~8.0 kg stock to ~2.5 kg with the SC-Project exhaust (≈ -5.5–6.25 kg).
• Race-proven design & build quality: SC-Project touts its roots in MotoGP, Moto2/Moto3, Superbikes — meaning this exhaust isn’t a budget aftermarket throwaway but built using “aeronautical-grade materials,” titanium link pipes, a large-diameter outlet, and quality construction meant to survive high heat and high RPM conditions.
• Aggressive look, compact styling, and premium finish: The CR-T muffler gives the R1 (or R1M) a more “race-bike” aesthetic — smaller, sleeker, purposeful. For riders who care about how the bike looks (not just performs), this is a big plus.
• Performance edge for aggressive / track-oriented riding: Because the CR-T is “race replica” kind of exhaust, it’s designed to release more exhaust volume efficiently — that generally means improved throttle response, freer revving, and a more “alive” feel in high-RPM zones (where R1 naturally shines). The “race-tested and race-proven” claim reflects that the design philosophy comes from real circuit-level engineering.
• Distinct, raw exhaust tone: Many riders choose the CR-T for the sound — the muffler is built for loud, aggressive exhaust notes that match the character of a liter-class superbike like the R1. It’s a statement piece as much as a performance part.
• Extremely loud — “race-only” noise levels: The CR-T for Yamaha R1 is rated at ~123 dB @ 6500 rpm (per the listing) and it does not include a dB-killer — so expect noise that’s much louder (and raw) than stock.
