Here is what our staff has to say about this Yamaha R9 exhaust.
- Significant weight reduction & performance gains: According to the manufacturer, this full-system exhaust gives about +7 hp and +5.5 Nm of torque at ~9500 rpm, compared with stock — which can meaningfully improve acceleration and high-RPM performance.
- Much lighter than stock Yamaha R9 exhaust: The system reportedly cuts several kilograms off the OEM exhaust (SC-Project claims over 65% lighter for its titanium + CR-T combo on R9). A lighter exhaust helps with handling, agility, and gives the bike a more responsive feel.
- High-end materials and build quality: The CR-T is crafted with titanium (headers, link-pipes) and offers a carbon-fiber or titanium muffler, a large-diameter outlet, plus a honeycomb mesh outlet and stone-guard grid — reflecting a “race-replica” build quality rather than cheap aftermarket.
- Aggressive exhaust note + styling: This exhaust transforms the bike’s tone and character — many riders choose it specifically for the deeper, louder, more aggressive sound and the aesthetic “race-bike” look. Manufacturers and sellers position it as the premium choice for riders wanting maximum presence.
- Track- or spirited-ride ready: Given its weight savings, power increase, and race-spec design, this exhaust is ideal if you ride aggressively, want to push the bike on track or twisty roads, or value performance over subtlety.
- Very loud — possibly too loud for street or daily commuting: The CR-T for Yamaha R9 is rated at ~119 dB at 5000 rpm according to official specs. That’s likely to be much louder than stock and potentially problematic for noise laws or with people nearby.
