SC Project CR-T Exhaust Carbon Fibre for S 1000 RR 2017-2018

SC Project CR-T Exhaust Carbon Fibre for S 1000 RR 2017-2018

SC‑Project is steeped in MotoGP and Moto2 championship development, bringing racetrack-tested innovations to their consumer exhaust lines. The CR‑T is their flagship race-replica muffler, recognized for performance and style—often seen on championship-winning bikes. It’s widely adopted due to its technological pedigree and striking aesthetics.

2. Construction & Aesthetics

• Carbon-fibre outer sleeve: lightweight with high heat resistance and a sleek sporty finish.

• Titanium mesh outlet cap: available optionally, providing both structural protection and an aggressive MotoGP-inspired look.

• Titanium link pipe: fully TIG‑welded to ensure a smooth, durable flow path and authentic racing construction.

• CNC‑machined titanium bushings and mounting hardware ensure flawless fitment. Hand‑crafted in Italy with laser-etched logo or riveted aluminium plate denoting premium build quality.

• Kit includes springs, screws, heat-shield stickers, homologation card, and a 24‑month warranty .

Visually, the carbon/titanium combo conveys race-ready aggression while maintaining refinement—bolder than SC’s S1 or SC1‑R.

3. Spec Performance & Weight Savings

According to SC-Project specs for the 2017–2018 S1000RR (Euro 4 approved):

• Power gain: +4.6 hp at ~9,850 rpm

• Torque gain: +7.3 Nm at ~7,800 rpm

• Weight savings: ~3.75 kg reduction, dropping from ~4.45 kg stock to ~0.7 kg for the CR‑T unit

These gains are solid for a slip‑on upgrade—especially torque improvement, enhancing mid- to top-end drive.

4. Installation Process & ECU Tuning

• Complete plug‑and‑play kit: all necessary hardware included for a bolt-on install—no cutting, no welding, no permanent modification

• Generally ECU remap not required due to Euro 4 homologation, but matching fuel tuning is highly recommended if fitted with fully open headers or under heavy load, to maintain safe air–fuel ratios.

Importantly, the CR‑T does not include a dB‑killer—confirm with seller whether a variant with titanium mesh is the EU homologated “street legal” option.

5. Sound Character & Riding Experience

The CR‑T delivers an unmistakable deep, raspy, race‑replica sound: aggressive and raw, tuned to evoke MotoGP audio fidelity. Rider impressions are unanimous—this is one of SC‑Project’s loudest systems

Quotes from the community highlight its unfiltered intensity:

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

It’s so loud that some owners tugged earplugs into every ride, describing ringing in the ears or discomfort during cruising—even in low rpm circumstances

6. Legal Status & Homologation

• Euro 4 approval with EC/ECE certification makes the CR‑T street legal for EU‑compliant bikes (2017–2018 S1000RR)

• Because no baffle is included, local noise limit enforcement may still catch violations even if technically homologated. Riders in sound-regulated areas may need to consider alternatives or verify noise insert availability.

7. Rider Feedback & Community Reactions

User reports reveal a consistent tone: love the performance and tone, but be cautious around volume.

• “My headers with SC‑Project can were obnoxious … most tracks balked.”

• “Phone mic was clipping … sounded like it was straight-piped.”

• Nevertheless, many riders admit that it feels thrilling precisely because of its volume and presence—making everyday riding an emotional experience.

Still, some regret daily use due to noise complaints or community friction.

8. Comparison to SC‑Project Alternatives

⚔ CR‑T vs GP70‑R vs S1 vs SC1‑R

• CR‑T (Carbon Fibre): Loudest, most aggressive sound, highest torque and power gains, best weight reduction (~3.75 kg).

• GP70‑R: Also loud and race-replica (titanium sleeve), but slightly softer tone and a bit lower torque gain (~+7.3 Nm vs ~+7.3 Nm similar) with around 0.7 kg weight (~3.7 kg saved)

• S1 (Titanium): When compared, S1 is quieter, more street-friendly, with modest gains (+4.9 hp, +5.8 Nm) and comfortable aesthetic with carbon end-cap.

• SC1‑R: Euro 5 homologated, quieter with removable dB‑killer, ideal for riders prioritizing daily legality and quieter street performance.

In short, CR‑T appeals to the rider who values raw sound and visual aggression above discretion.
