SC Project CR-T Exhaust Carbon Fibre with stoneguard Grid for BMW S 1000 R 2021-2024

SC Project CR-T Exhaust Carbon Fibre with stoneguard Grid for BMW S 1000 R 2021-2024

1. Overview & Fitment

The SC‑Project CR‑T Carbon Fibre with Stoneguard Grid, part number B39A‑38CR, is a plug‑and‑play slip‑on designed for BMW S 1000 R models 2021 through 2024, Euro 5 homologated for street‑legal use

Built as part of SC’s MotoGP‑derived range, it’s engineered to deliver maximum sound, lightweight performance, and race replica aesthetics. This package includes the carbon fibre body, titanium end cap and link pipe, and a titanium mesh stoneguard over the outlet. Total system weight is ~0.9 kg versus the OEM’s 2.3 kg, giving a ~1.4 kg weight saving

2. Performance Enhancements

Power gains are modest but tangible: +0.6 hp and +0.7 Nm at around 9,400 rpm. While this isn’t a dramatic dyno jump, combined with the substantial weight reduction, throttle response improves and the bike feels livelier and more responsive—especially during quick transitions and hard braking.

3. Build Quality & Hardware Highlights

• Carbon fibre sleeve: Aerospace-grade, lightweight, and visually refined

• Titanium end cap and pipes: TIG-welded, CNC-finished for precise alignment and premium quality

• Titanium mesh stoneguard grid on the outlet: aesthetic flair and minor debris protection

• Plug-and-play kit includes springs, screws, heat-shield and 24‑month warranty and homologation card

Installation is straightforward using OEM headers and components. No ECU remap is required for basic fitment and operation.

4. Sound Profile & Legal Considerations

The CR‑T is engineered for pure racing tone—deep, bold, and unmistakable. It does not include a removable dB‑killer, which means the sound level is fixed and unapologetically loud. SC advertises it as a “race replica exhaust designed for the aggressive rider who likes it light and loud”

Noise figures published estimate ~100 dB at 6,750 rpm, which on real world riding can peak higher, likely exceeding 110–120 dB during full throttle runs. Rider forums corroborate this—users call it “the loudest… if you’re just looking to make MotoGP sounds on the street” and warn of ear‑ringing, headaches, and public backlash

Legally, it is Euro 5 approved, but many users—particularly in noise-controlled jurisdictions—report potential non-compliance in practice because of dynamic dB spikes. Even though SC supplies a homologation card, there’s no internal baffle, so compliance relies on static testing rather than real-world attenuation.

5. Real‑World Rider Feedback

Community feedback delivers a consensus:

“What would be the loudest exhaust?… full headers Arrow… then an SC project can. And it’s obnoxious… Most tracks balked at it.”
“I had a CRT… it was so loud I was getting headaches after rides.”

One user emphasized:

“It sounds good… but people will hate you.”

Others discussing legality noted that despite Euro certification, local noise ordinances may still prohibit the exhaust in day-to-day riding—even though no police stops occurred in some US states

There are also frequent concerns about counterfeit units. Genuine SC-Project exhausts have clean TIG welds, serial numbers, and build quality. Cheaper imitators can be dangerously loud or poorly constructed

6. Comparison with Other SC‑Project Models

The CR‑T sits at the top for radical sound, raw aesthetic, and racing punch—best reserved for riders who prioritize drama over discretion. For more daily-friendly options, SC1‑R offers dB-killer hardware and quieter tone without sacrificing style

7. Pros & Cons

✅ Advantages

• Significant weight savings (~1.4 kg) improve agility and handling

• Racing DNA design with premium carbon and titanium, plus stoneguard mesh details

• Distinctive deep, aggressive sound signature unmatched in street-legal SC range

• Euro 5 homologation and 24-month warranty included

• Plug-and-play fitment with no ECU remap needed

❌ Drawbacks

• Extremely loud—can cause hearing fatigue or local complaints

• No removable baffle/deadening, so volume is non-adjustable

• Performance gains are modest—emphasis is on weight and sound

• Potential non-compliance with local noise ordinances during dynamic riding

• Higher price (~€640 internationally, ~₹125K+ in India) for a niche sound profile

• Risk of counterfeit units if not sourced from reputable dealers

8. Who This Exhaust Is For

Ideal for riders who:

• Want maximum sound impact and street presence

• Crave MotoGP-derived aesthetics and tone

• Ride aggressively, occasionally take the bike on track, and appreciate weight reduction

• Can tolerate loudness and stick with ear protection

• Buy from authorized SC-Project dealers to ensure authenticity and warranty

Not suitable for riders who:

• Regularly commute or ride in noise-sensitive areas or residential neighborhoods

• Prefer quiet or moderate exhaust levels and want flexibility of sound control

• Seek high dyno gains—here, gains are minimal without remap

• Value low cost or subtle upgrades

9. Pricing & Availability

• International MSRP: approx €640 for carbon fibre version (part B39A‑38CR), delivered within 5–20 working days. The titanium version with mesh uses part B39A‑38TR at similar pricing

• India: Sellers like Superbikestore list CR‑T kit for ₹125,000, with 4–6 week delivery and no returns on imported products

• Beware of fakes: authentic SC-Project exhausts cost significantly more than ₹30 K–50 K; anything cheap likely fake and uncertified

10. Final Thoughts

The SC‑Project CR‑T Carbon Fibre with Stoneguard Grid for BMW S 1000 R (2021–2024) is a bold, high-end upgrade built for riders chasing a loud, race-ready experience. It excels in craftsmanship, identity, and dramatic sound—but it is unapologetically loud and non-adjustable, making it more suited to track days or open roads than everyday urban riding.

Whether it’s worth it comes down to how you ride, where you ride, and whether you’re okay with triggering reactions—both visceral and legal—from your exhaust. If you prefer high drama with minimal compromise, this is one of SC’s elite offerings. But if usability, comfort, or moderation matter more, quieter alternatives like SC1‑R or Akrapovič might be better fits.
