Benelli TNT125 TNT135 Tornado + Naked

The benelli tnt125 is a popular entry-level motorcycle that combines Italian styling with practical performance, and upgrading its exhaust system is one of the most effective modifications you can make to enhance both sound and power delivery. At Quill Performance Exhausts, we specialise in manufacturing high-quality aftermarket exhaust systems designed specifically for the Benelli TNT125, TNT135 Tornado, and Naked models, delivering superior performance and an unmistakable exhaust note that will transform your riding experience.

About the Benelli TNT125 TNT135 Tornado Exhaust System

This premium motorcycle exhaust system is precision-engineered for the benelli tnt125, TNT135 Tornado, and Naked variants, providing a complete link pipe fitting solution that integrates seamlessly with your motorcycle’s existing setup. Each exhaust kit includes everything you need for a straightforward installation: one stainless steel 304 CNC mandrel-bent link pipe, one stainless steel exhaust strap, one exhaust strap rubber, and one exhaust hanging bracket.

The quality of materials used ensures long-lasting durability and resistance to corrosion, even in the harshest British weather conditions.

Our exhaust systems are designed to fit straight onto the standard OEM downpipes without requiring any modifications to your motorcycle’s frame or exhaust mounting points. This direct-fit approach means you can complete the installation in your own garage with basic tools, making it an ideal upgrade for both experienced mechanics and enthusiastic home wrenchers alike.

The mandrel-bent construction of the link pipe ensures smooth internal gas flow with no restrictions or crimped sections that could impede exhaust gases, resulting in optimised performance throughout the rev range.

Performance Benefits of Upgrading Your Benelli TNT125 Exhaust

When you upgrade the exhaust system on your benelli tnt125, you’re not just changing the sound—you’re fundamentally improving how efficiently your engine breathes. Our exhausts are manufactured to give maximum power without the need to alter the fueling, making them a genuine plug-and-play performance upgrade for riders running standard air filtration and catalytic converters. The improved exhaust gas evacuation reduces back pressure, allowing your engine to expel spent gases more efficiently and draw in fresh air-fuel mixture more effectively.

However, if you’ve already installed an aftermarket air filter or a de-cat system on your Benelli, having the bike’s fueling professionally mapped or adjusted will always complement the engine performance and efficiency gains from your new exhaust. The combination of increased air intake, freer-flowing exhaust, and optimised fueling creates a synergistic effect that maximises your motorcycle’s potential.

Many riders report noticeable improvements in throttle response, mid-range torque, and top-end power after completing a full intake and exhaust upgrade with proper fueling adjustments.

Why Choose Quill Performance Exhausts for Your Benelli TNT125

At Quill Performance Exhausts, we take pride in our UK-based manufacturing process, where each exhaust system is crafted with meticulous attention to detail. The use of 304-grade stainless steel ensures your exhaust will maintain its appearance and structural integrity for years to come, whilst the CNC mandrel-bending process guarantees consistent internal diameter throughout each bend, maximising flow characteristics.

Unlike cheaper alternatives that may use crush-bent pipes or inferior materials, our exhausts represent genuine value for money through their combination of performance, durability, and aesthetic appeal.

The distinctive sound produced by a Quill exhaust on a benelli tnt125 is another key benefit that riders consistently praise. We’ve carefully engineered the acoustic properties to deliver a deep, sporty tone that enhances the riding experience without being antisocially loud. This balance makes our exhausts suitable for everyday use, commuting, and weekend rides alike. You can hear the difference in our YouTube demonstration video, which showcases the exhaust note under various riding conditions and RPM ranges.

Installation and Compatibility for the Benelli TNT125 TNT135 Models

Installation of this exhaust system is straightforward for anyone with basic mechanical knowledge. The kit includes all necessary mounting hardware, and because it’s designed to connect directly to your standard downpipes, you won’t need to purchase additional adaptors or brackets. The exhaust strap and rubber mount provide secure, vibration-dampening attachment points that prevent unwanted movement whilst allowing for the natural thermal expansion of the exhaust components during operation.

This exhaust is specifically compatible with the Benelli TNT125, TNT135 Tornado, and Naked models, ensuring perfect fitment regardless of which variant you own. For riders looking for a complete exhaust solution from headers to tail pipe, you might also consider our Benelli TNT125 TNT135 Tornado +TNT Naked De-Cat Down-Pipe Exhaust header and Rear Silencer, UK Made, which offers even greater performance potential by replacing the restrictive standard catalytic converter and header pipes.
