SC Project CR-T Carbon Fibre with stoneguard Grid exhaust for BMW S 1000 RR (2017-2018)

SC‑Project’s CR‑T muffler is rooted in MotoGP and Moto2 racing expertise. It’s the brand’s most iconic “race‑replica” slip‑on system—the same design used by championship teams. The stoneguard‑grid version adds a titanium mesh outlet that mimics the style of real race exhausts.

2. Materials & Visual Design

• Carbon‑fibre outer sleeve: lightweight and visually striking with premium heat resistance.

• Stoneguard (titanium mesh) exit grid: protects the outlet, gives a distinct aggressive aesthetic.

• Titanium end cap and link pipe: fully TIG‑welded for race‑level durability.

• CNC-machined titanium bushings and mount hardware ensure precision fitment.

• Finish includes riveted aluminum MotoGP‑style branding plaque.

• A high‑quality carbon heat shield is included, plus homologation card and stickers.

Visually, the CR‑T stands out with its bold carbon/titanium contrast and high-performance styling.

3. Performance, Weight Savings & Technical Specs

Official SC‑Project Euro 4 homologated data for the 2017–2018 S1000RR:

• Power gain: +4.6 hp @ 9,850 rpm

• Torque gain: +7.3 Nm @ 7,800 rpm

• Weight reduction: —3.75 kg (from ~4.45 kg to ~0.7 kg)

The combination of reduced mass and increased mid‑high rpm output improves throttle response and overall bike dynamics.

4. Installation & ECU Requirements

• Plug-and-play slip‑on kit: complete with link pipe, springs, screws, stickers, carbon heat shield, 24‑month warranty, and homologation card. No cutting or adaptation required.

• ECU remap not required for standard fitment: designed to work under Euro 4 rules. However, if you pair it with staged headers or aggressive tuning, ECU tuning or a fuel controller is advised to maintain safe air-fuel ratios.

5. Sound Profile & Rider Experience

The CR‑T is renowned for delivering one of the loudest and most raw sounding slip‑ons SC offers:

• Deep, raspy, race-like growl with prominent pops on deceleration.

• The stoneguard grid adds a sharper edge to the tone.

• Real‑world impressions are consistent:

  “It’s stupid loud … throws flames on deceleration … sounds super throaty.”
  “SC‑Project CR‑T is the loud, MotoGP style exhaust. It’s the loudest.”

Users consistently report wearing earplugs even for short rides to avoid ear ringing or discomfort.

6. Legal & Noise Compliance

• Fully EC/ECE Euro 4 approved, making it technically street-legal with valid homologation.No dB‑killer included by default—even in the stoneguard grid variant—so actual noise levels may exceed local limits.

• Many owners report being black‑flagged at tracks and cited by law enforcement due to decibel output.

Always verify local noise regulations and check whether you can source a compliant version before purchasing.

7. Community Feedback & Real-World Impressions

• Impressive craftsmanship and look, but many regret daily use due to neighbors or noise complaints.

• Several riders comment on the difficulty of ignoring it when riding close to others—“people grimacing” on close-quarter rides.

• Some reports about fakes in the market; genuine SC units bear serial numbers and branding details.

Overall sentiment: exceptional performance and sound—beware of decibel downsides.
