Benelli TNT125 TNT135 Tornado +TNT Naked De Cat Down-Pipe Exhaust header UK Made

The benelli tnt125 tnt135 tornado +tnt naked de cat down-pipe exhaust header uk made by Max Torque Cans is the definitive upgrade for any Benelli TNT or Tornado owner who wants to unlock genuine performance gains without compromising reliability or build quality. Crafted right here in the United Kingdom from premium T304 stainless steel, this is not an imported, mass-produced part — it is a precision-engineered British performance header built to exceed OEM standards in every meaningful way.

If you have been frustrated by the restrictive, heavy, and thermally inefficient standard front pipe fitted to your Benelli, you are not alone. The factory header is designed around emissions compliance first and performance second. Our de cat down-pipe changes that priority completely, giving your engine the freedom to breathe properly, evacuate exhaust gases more efficiently, and deliver the power it was always capable of producing.

Why Choose the Benelli TNT125 TNT135 Tornado +TNT Naked De Cat Down-Pipe Exhaust Header UK Made?

There are plenty of options out there, but very few can match what Max Torque Cans delivers on quality, fitment, and performance. When you invest in this benelli tnt125 tnt135 tornado +tnt naked de cat down-pipe exhaust header uk made, you are getting a component that has been designed, measured, and manufactured to exact tolerances by experienced exhaust fabricators based in the UK. No guesswork, no compromise.

Here is what makes this header stand out from the crowd:

• British-made T304 stainless steel construction — corrosion-resistant, durable, and built to last the lifetime of your bike.
• Dramatic weight saving — the standard Benelli downpipe weighs a hefty 3.4 kg. Our performance header weighs just 1.1 kg, saving you an impressive 2.3 kg of dead weight from the front of the bike.
• Optimised exhaust gas flow — the improved internal bore and smooth bends are engineered to reduce back pressure and allow gases to exit the engine faster and more efficiently, translating directly into more usable power.
• Includes O2 Lambda sensor boss — your standard OEM sensor can be refitted without any modification, keeping your bike’s fuelling management intact.
• Free removable DB killer (baffle) included — giving you the flexibility to run a quieter, more compliant note when needed, or open it right up for that raw, mechanical sound when you want it.
• No gasket required — this header fits up to the standard rear silencer without the need for a factory gasket. Simply apply a normal silicone-based sealant to achieve a gas-tight seal. It is clean, simple, and effective.

Fitment Guide for the Benelli TNT125 TNT135 Tornado +TNT Naked De Cat Down-Pipe Exhaust Header UK Made

One of the most important things to us at Max Torque Cans is that our products fit properly. This benelli tnt125 tnt135 tornado +tnt naked de cat down-pipe exhaust header uk made has been designed to mirror the exact routing and mounting points of the standard front pipe. You will not need to drill, cut, weld, or modify anything on your motorcycle to make it fit. Simply remove the OEM header, drop ours in its place, refit your lambda sensor, and seal the rear joint with silicone sealant.

This header is compatible with the following Benelli models:

• Benelli TNT125
• Benelli TNT135
• Benelli Tornado
• Benelli +TNT Naked

The pipe connects directly to the standard rear silencer, making it an ideal upgrade whether you are running the OEM can or have already fitted an aftermarket performance silencer. The fitment is clean, professional, and will look as though it belongs on the bike — because it was made to.

Performance and Fuelling — What to Expect from the Benelli TNT125 TNT135 Tornado +TNT Naked De Cat Down-Pipe Exhaust Header UK Made

Max Torque Cans exhausts are engineered to deliver maximum power gains without requiring you to alter the standard fuelling. In most cases, riders fit this benelli tnt125 tnt135 tornado +tnt naked de cat down-pipe exhaust header uk made and immediately notice improved throttle response, a more linear power delivery, and a much more satisfying exhaust note — all without touching the fuel map.

That said, if you have already fitted an aftermarket air filter or are running any additional modifications alongside this de cat header, we would always recommend having the fuelling professionally mapped or reviewed. Complementing an improved air intake with an optimised exhaust flow and a properly tuned fuel map will always yield the best results. It is not strictly necessary with a standard bike, but it is the smart move if you are building a more comprehensive performance package.

The removal of the standard catalytic converter housing allows exhaust gases to travel through the pipe with significantly less restriction. Combined with the smoother, more considered internal geometry of our header, the engine can effectively breathe better on both the intake and exhaust cycle. For a small-capacity machine like the TNT125 or TNT135, every efficiency gain matters — and this is one of the most impactful single upgrades you can make.

Installation Notes for Your Benelli TNT125 TNT135 Tornado +TNT Naked De Cat Down-Pipe Exhaust Header UK Made

Installing the benelli tnt125 tnt135 tornado +tnt naked de cat down-pipe exhaust header uk made is a straightforward job for anyone with basic mechanical confidence and the right tools. Here are a few practical tips to help you get the best result:

• Allow the engine to cool completely before beginning removal of the standard header. Working on a hot exhaust is dangerous and makes the job harder.
• Use a quality penetrating fluid on the standard mounting bolts a few hours before starting. Factory fasteners can be stubborn, particularly if the bike has seen any wet weather.
• Refit your OEM O2 lambda sensor into the boss provided on our header before fully tightening and sealing the pipe. This keeps your bike’s ECU working correctly.
• Apply a silicone-based exhaust sealant to the rear connection point where this header meets the rear silencer. This replaces the factory gasket and creates an equally effective, gas-tight seal.
• Run the engine briefly after installation and check all connection points for any signs of leaks before riding. A quick visual check at operating temperature is always good practice.

Frequently Asked Questions

Will this de cat header affect my bike’s fuelling?

In the vast majority of cases, the benelli tnt125 tnt135 tornado +tnt naked de cat down-pipe exhaust header uk made can be fitted to a standard, unmodified Benelli without any fuelling changes. Our headers are specifically designed to deliver improved power without requiring a remap on a stock bike. If you have additional modifications such as an aftermarket air filter or performance carburettor jetting, a professional fuel review is advisable to get the most from the setup.

Does it come with everything I need to fit it?

Yes. The header arrives complete with the O2 lambda sensor boss for your OEM sensor and a free removable DB killer baffle. You will need to supply your own silicone-based exhaust sealant for the rear joint, but no specialist parts or gaskets are required.

Is the DB killer easy to remove?

Absolutely. The removable baffle is designed for quick and easy removal without tools in most cases. Take it out for a more open, aggressive exhaust note on track days or open road rides, and refit it when you need to keep things a little more discreet.

The standard Benelli downpipe tips the scales at 3.4 kg. The benelli tnt125 tnt135 tornado +tnt naked de cat down-pipe exhaust header uk made from Max Torque Cans weighs just 1.1 kg — that is a saving of 2.3 kg from a single bolt-on upgrade.
