About the Benelli TNT125 TNT135 Tornado Rear Silencer

Designed specifically for the Benelli TNT125, TNT135 Tornado, and TNT Naked variants, this UK-made rear silencer has been engineered to provide optimal performance without requiring any modifications to your motorcycle’s fueling system. Each unit is handcrafted by skilled technicians at our British manufacturing facility, ensuring consistent quality and performance that meets the demanding standards expected by performance-minded riders.

Please note: This listing is for the rear silencer only. For those seeking maximum performance gains, we also manufacture de-cat headers for this model, which can be purchased separately or as a complete system. The Benelli TNT125 TNT135 Tornado +TNT Naked De-Cat Down-Pipe Exhaust header and Rear Silencer represents our complete exhaust solution for riders demanding ultimate performance.

Key Features and Performance Benefits of This Rear Silencer

Our exhausts are manufactured to deliver maximum power gains straight out of the box. The engineering philosophy behind every Quill Performance rear silencer centres on optimising exhaust gas flow, reducing back pressure, and eliminating unnecessary weight—all whilst maintaining a perfectly tuned exhaust note that complies with UK noise regulations.

Dramatic Weight Reduction with Our Rear Silencer

One of the most immediately noticeable benefits of upgrading to a Quill Performance rear silencer is the substantial weight saving. The standard factory downpipe weighs approximately 3.4 kilograms, whereas our precision-engineered downpipe weighs just 1.1 kilograms. This represents a remarkable weight saving of 2.3 kilograms from your motorcycle’s rear end, improving handling characteristics, acceleration, and overall agility. Reduced unsprung mass translates directly to improved suspension performance and more responsive cornering behaviour.

Performance Optimisation Without Fueling Modifications

Unlike many aftermarket exhaust systems that require expensive dyno tuning or ECU remapping, our rear silencer has been specifically designed to work with the standard fueling maps on your Benelli TNT125, TNT135 Tornado, or TNT Naked. This plug-and-play approach means you can enjoy immediate performance benefits without additional costs or complexity.

However, if you’ve already fitted an aftermarket air filter or installed our de-cat headers, we do recommend having your motorcycle’s fueling professionally optimised to fully complement the enhanced breathing capability and maximise engine performance and efficiency.

Why Choose the Quill Performance Rear Silencer for Your Benelli?

Quill Performance Exhausts has built a reputation for delivering race-quality components at realistic prices. Every rear silencer leaving our UK workshop undergoes rigorous quality control procedures to ensure it meets our exacting standards. We use premium-grade stainless steel throughout the construction, selected specifically for its durability, corrosion resistance, and acoustic properties. The welds are executed by experienced fabricators, and each unit is pressure-tested before dispatch.

The performance gains extend beyond simple power increases. Riders consistently report improved throttle response throughout the rev range, a more linear power delivery, and enhanced mid-range torque that makes overtaking and urban riding significantly more enjoyable. The distinctive exhaust note provides satisfying acoustic feedback without becoming intrusive or antisocial—a careful balance that reflects our understanding of real-world riding conditions.

Installation is straightforward for anyone with basic mechanical skills and standard workshop tools. The rear silencer mounts using the existing hanger points and bolt patterns, ensuring perfect fitment without modifications to your motorcycle. For those less confident with spanner work, any competent motorcycle workshop should be able to complete the installation in under an hour.

Complementary Performance Upgrades

For riders seeking maximum performance potential, pairing this rear silencer with our de-cat headers creates a complete exhaust system that delivers significant gains across the entire rev range. The Benelli BN125 De-Cat Down-Pipe header & Exhaust UK Made demonstrates our expertise across the Benelli range, with similar engineering principles applied to various models.

When upgrading your exhaust system, it’s worth considering complementary modifications such as a high-flow air filter and professional fueling adjustments. These modifications work synergistically to optimise your engine’s breathing capability.
