BMW S 1000 RR 2017-2018 SC project CR-T titanium exhaust

The CR‑T is SC-Project’s signature “race‑replica” slip‑on system, developed directly from MotoGP / Moto2 championship experience. It’s frequently used by professional teams, and dubbed their most iconic model—built for optimal performance and radical sound.

2. Materials, Design & Visual Impact

• Full Titanium Construction: muffler body, end-cap, and link pipe are made from aerospace-grade titanium, TIG-welded for strength and thermal resilience.

• Titanium Mesh Stone‑Guard: optional exit grid providing added outlet protection and an aggressive, MotoGP-inspired styling.

• Conical stepped design: large outlet, deep expansion chamber—both performance and aesthetic benefits.

• Precision hardware: CNC-machined titanium bushings, springs, screws, and TIG-welded brackets ensure perfect fit. Laser-engraved logo underscores premium build quality.

• Complete kit: includes link pipe, heat shield stickers, homologation card, SC-Project stickers, and a 24‑month factory warranty.

Visually, the CR‑T titanium unit is sleek, minimalist, and visibly high-tech—cleaner than carbon versions, with a stealth race aesthetic.

3. Performance Specs & Weight Savings

From SC-Project Euro 4 certified data for the 2017–2018 S1000RR:

• Power gain: +4.6 hp @ ~9,850 rpm

• Torque gain: +7.3 Nm @ ~7,800 rpm

• Weight savings: approx. –3.75 kg (stock ~4.45 kg → SC ~0.7 kg)

This weight reduction noticeably improves flick‑ability, braking—especially uphill acceleration and mid‑top‑end punch.

4. Installation & ECU Considerations

• Plug‑and‑play slip‑on: quick swap of stock silencer with full titanium link pipe; includes all mounting hardware and homologation card. No welding or cutting required.ECU remap not required: Euro 4 approval supports street‑legal use without tuning. However, after installing racing headers or aggressive tuning, riders may wish to remap or use a fuel controller to prevent lean running.

• No built-in dB-killer: the CR‑T titanium version does not include a baffle. Even variants with mesh only marginally reduce volume and may not meet local noise limits in practice.

5. Sound Profile & Real‑World Feeling

The CR‑T titanium delivers a raw, guttural, race-inspired sound, arguably SC-Project’s most intense slip‑on tone:

• Deep, raspy, snarl on throttle with explosive pops on decel. The mesh outlet adds crisp harshness.

• Reputation for extreme loudness: wildlife alerts—phone mics clip; neighbors dread it.

• Feature hearsay from owners:

  “SC‑Project CR‑T is the loud, MotoGP style exhaust … it’s the loudest.”
  “It was so loud I was getting headaches after rides.”

Owners strongly advise riding with ear protection even on short rides to prevent ringing or possible long-term hearing damage.

6. Legal Compliance & Homologation Status

• The 2017–2018 CR‑T titanium slip‑on holds EC/ECE Euro 4 type-approval, making it technically street legal in compliant regions. It includes an official homologation certificate.

• Despite this, the absence of a dB‑killer often leads to real-world noise levels exceeding regulatory thresholds—resulting in track bans and citations.

• Riders report being black-flagged at noise-sensitive tracks and sometimes by roadside enforcement even with homologation.

7. Community Feedback & Owner Perspectives

Forums and Reddit provide a common theme: thrill in performance, regret in noise complaints:

• Many regret daily usage: loud enough to irritate neighbors, attract unwanted attention.

• Reported difficulty ignoring it even at distance; described as obnoxious or overbearing on public roads.

• Some mention counterfeit units—genuine CR‑T exhausts carry serial numbers and polished craftsmanship.

• Others praised its build quality, calling welds “beautiful” and noting it felt superior to compare brands.

8. Pros & Cons Summary

Pros
