SC Project Exhaust GP70-R Titanium for S 1000 R 2017-2020

SC Project Exhaust GP70-R Titanium for S 1000 R 2017-2020

1. Design & Build Quality

The GP70‑R is SC‑Project’s most iconic silencer, developed with MotoGP-level expertise and a racing DNA. For the 2017–2020 BMW S 1000 R, the part number B27A‑T70T represents a full-titanium construction: muffler body, link pipe, and end cap. Advanced TIG-welded brackets, CNC-machined bushings, and a clean, laser-etched SC logo enhance both function and aesthetics.

This specific kit is Euro‑4 homologated (street legal) but does not include a removable dB‑killer, so it sacrifices volume control for raw sound performance.

2. Performance Gains

Power & Torque

According to SC’s specs for the S 1000 R model, the GP70‑R offers approximately +3.6 hp at 9,600 rpm and +5.8 Nm at 7,500 rpm, delivering sharper throttle response, more mid-range punch, and better top-end delivery compared to stock

Weight Savings

SC claims a reduction from about 2.7 kg factory weight to just 0.8 kg—a 1.9 kg (≈70%) weight drop. This dramatically improves rear-mid handling, braking feel, and inertia management

3. Sound & Noise Levels

Acoustic Signature

GP70‑R is renowned for its raw, throaty racing tone. With no dB‑killer fitted, expect an aggressive and attention-grabbing sound—ideal for track or spirited riding

Real‑World Noise Feedback

User forums consistently flag SC‑Project cans as very loud:

“The SC project can… it’s obnoxious. Most tracks balked at it.”
“SC Project is one of the loudest options… I love the sound of SC, but they are ridiculously loud.”

An S 1000 R owner reported idle noise around 95–100 dB with just the silencer and stock cat—a full titanium system would likely push peaks above 120 dB, which is extreme and potentially harmful over longer rides.

4. Fitment & Installation

• Kit includes: slip-on titanium muffler, titanium link pipe, springs, screws, SC‑Project stickers, homologation card, and a 24‑month official warranty provided by SC‑Project.

• Installation: designed as “plug‑and‑play” for BMW S 1000 R 2017‑2020 models. No remapping typically required unless tuning for full performance.

• Street legality: Euro‑4 approved and comes with homologation certificate, although there’s no modular noise control built in (no baffle).

5. Pricing & Availability (India & International)

Europe & Global Pricing

On SC‑Project’s official site, the GP70‑R muffler is listed at €760, with expected delivery in 5–20 working days.

India

Importers like BikeGear and Custom Elements price the titanium GP70‑R at around ₹119,000–₹126,000, including duties and taxes. Delivery often takes 4–6 weeks.

Beware Knockoffs

Reddit users warn against fake SC exhausts sold cheaply—often lacking build quality, certification, and authenticity. Genuine SC units usually cost above ₹30,000 and come with serial verification.

6. Real‑World Impressions from Riders

Although direct feedback on the S 1000 R variant is limited, generic SC‑Project reviews reflect consistent themes:

• Volume: Loudness is a deal-breaker for many: “Some tracks black‑flag SC installs… it sounds awesome but it’s too loud”.

• Sound quality: Many say SC sounds visceral and unique, but often prefer brands like Akrapovic for better balance between sound and manageability.

• Durability concerns: A few reports cite issues with titanium welds in other contexts. A cobalt-carbon layout may hold up better in crashes; carbon or stainless systems tend to be more crash-damage resilient.

7. Side‑by‑Side: SC‑Project GP70‑R vs Other SC Slip‑Ons

GP70‑R sits in the middle—more extreme than SC1‑R (which offers a baffle), but slightly milder than the fully race-focused CR‑T.

8. Pros & Cons Summary

Advantages

• Large weight reduction (~1.9 kg) improves responsiveness and handling.

• Measurable performance boost: +3.6 hp and +5.8 Nm in the upper rev range.

• Premium titanium build with CNC and laser detailing.

• Euro‑4 homologation allows street legality in many markets.

• Track‑inspired sound and looks make a bold statement.

Drawbacks

• Extremely loud; no onboard mechanism to tame sound.

• Not suitable for long rides or noise-sensitive zones without hearing protection.

• No removable baffle—limited flexibility.

• High import price—around ₹120K+ in India.

• Risk of counterfeit purchases if authenticity isn’t verified.

• Durability of titanium welds over time or crashes can be a concern

9. Who Should Choose the GP70‑R?

• If you’re a rider who values racing character, dramatic sound, and lightweight engineering, and you ride aggressively or use your bike on occasional trackdays, GP70‑R delivers.

• If you commute daily, ride in urban or residential areas, or prefer moderate volume control, you may find it overbearing.

• Consider SC1‑R instead—with a removable dB‑killer, similar style, and slightly tamer sound.

• Other high-quality alternatives explored by users include Akrapovic or Arrow slip‑ons, which balance performance and volume better in community comparison.
