SC PROJECT S1 EXHAUST FULL SYSTEM 3-1 FOR TRIUMPH TRIDENT 660 (2021-2024)

The Triumph Trident 660 sc-project-s1-ex…nt-660-2021-2024/ has quickly earned its place as one of the best entry-level middleweight roadsters. With its lively triple-cylinder engine, modern styling, and everyday usability, it appeals to both new and seasoned riders alike. But if you’re ready to unlock its full potential in sound, performance, and weight reduction, the SC-Project S1 Full System 3-1 Exhaust delivers a serious upgrade.

This isn’t just a slip-on. The S1 is a complete, racing-inspired exhaust system, specifically engineered for the Trident 660. SC-Project—renowned for powering machines in MotoGP and WorldSBK—infuses this system with the same high-performance DNA, creating a ride experience that feels sharper, louder, and more thrilling.

Design & Construction: A Masterpiece of Lightweight Engineering

SC-Project builds the S1 system entirely from aerospace-grade titanium, known for its strength and lightness. This leads to a significant weight reduction over the stock exhaust, enhancing agility—especially in corners and quick transitions.

From the header pipes to the collector and muffler, each part follows a clean, flow-optimized layout. Carefully curved routing and precision welds reduce resistance and promote efficient gas flow, helping the engine breathe more freely.

The system features SC-Project’s iconic conical S1 muffler, finished in matte titanium and capped with carbon fiber. Compact and aggressive, it pairs perfectly with the Trident’s modern design. Its low-slung position enhances the bike’s profile without sacrificing clearance or everyday comfort.

Sound: The Inline-Triple Roars to Life

Triumph’s triple-cylinder engine already has a unique tone—but the S1 exhaust amplifies it with raw energy. At idle, it offers a deep, raspy growl. Twist the throttle, and the bike releases a savage high-rev scream, giving off a proper supersport vibe while preserving the triple’s character.

This exhaust system delivers crisp, dynamic feedback that makes you feel more connected to the engine. It’s aggressive without sounding obnoxious. For riders in areas with noise limits, SC-Project includes a removable dB killer, letting you adjust volume while keeping the tone intact.

Performance Gains: Real Improvements, Not Just Noise

The S1 system improves more than just sound. Thanks to its weight savings and free-flowing design, you’ll notice:

• Faster throttle response, particularly in low and mid-range RPMs

• Smoother, more linear torque delivery, making the ride feel more fluid

• Modest horsepower gains, especially when paired with an ECU remap

• Better heat management and slightly improved fuel efficiency

By removing the restrictive catalytic converter and replacing the entire exhaust path, the engine can breathe with less resistance. As a result, it runs cooler, responds quicker, and pulls stronger—especially during spirited riding.

Installation: Precision Fit, Minimal Fuss

SC-Project designs the S1 system for a direct bolt-on installation. It uses the Trident’s factory mounting points, so you won’t need to cut or modify anything. With just basic tools and some mechanical confidence, most riders can finish the installation in under two hours.

The system includes all required hardware, gaskets, and step-by-step instructions. Once fitted, it integrates cleanly with the bike’s design—no awkward gaps, rattling parts, or issues with accessories like panniers or stands.

Street Legality & ECU Tuning

The S1 Full System is designed primarily for track and closed-course use, as it doesn’t include a catalytic converter and may exceed legal noise limits in some regions. Many riders still use it on the street where local laws allow—but always check your area’s regulations first.

To fully unlock the benefits of the system, pair it with an ECU remap or tuning module. This ensures the engine runs at peak efficiency with the new exhaust flow, delivering smoother operation and maximizing gains.
