Benelli TNT125 & TNT135 Tornado +TNT Naked Ø32mm De Cat Down-Pipe

The benelli tnt125 & tnt135 tornado +tnt naked Ø32mm de cat down-pipe from Max Torque Cans is one of the finest British-made performance upgrades available for your Benelli, engineered to unlock genuine power gains whilst shedding significant weight from your motorcycle. If you’re looking to transform the way your TNT125, TNT135, Tornado, or TNT Naked rides, sounds, and performs, you’ve come to exactly the right place. This is a properly engineered piece of kit — not an off-the-shelf import — and every single one leaves our workshop built to exacting standards using premium T304 stainless steel.

At Max Torque Cans, we’ve spent years developing performance exhausts that deliver real-world results. The benelli tnt125 & tnt135 tornado +tnt naked Ø32mm de cat down-pipe is the product of that dedication — born from listening to Benelli riders, understanding their frustrations with heavy, restrictive OEM pipework, and engineering something measurably better in every respect. We don’t cut corners, we don’t compromise on materials, and we don’t release a product until it performs exactly as intended on the road.

What’s Included With the Benelli TNT125 & TNT135 Tornado +TNT Naked Ø32mm De Cat Down-Pipe

When your order arrives, you’ll find everything needed to get straight to work. The package includes a full set of British-made T304 stainless steel front pipe and header, precision-formed to a Ø32mm diameter for optimised gas flow. Alongside the pipework, you’ll receive an integrated Powerbomb baffle and a purpose-made fitting bracket, ensuring a clean, secure installation that mirrors the OEM setup in terms of positioning — but surpasses it in every other respect.

• Material: T304 Stainless Steel — corrosion-resistant, durable, and built to last the lifetime of your bike
• Diameter: Ø32mm front pipe and header for improved gas flow and performance
• Powerbomb baffle: Included as standard, adding a refined tone that’s louder than stock yet remains within road-legal limits
• Fitting bracket: Supplied with the kit for a straightforward, hassle-free installation
• Lambda sensor port: Pre-drilled and ready for your OEM lambda sensor to be refitted with zero fuss
• Cat box removed: This is a de-cat design, meaning the restrictive catalytic converter is eliminated entirely for freer breathing and more power
• Weight saving: The standard OEM downpipe weighs 3.4 kg. Our downpipe weighs just 1.1 kg — a saving of 2.3 kg from a single component

That weight reduction alone is remarkable. Removing 2.3 kg from the exhaust side of your Benelli directly improves handling, acceleration, and the overall riding experience. Combined with the improved gas flow from the de-cat design, the benelli tnt125 & tnt135 tornado +tnt naked Ø32mm de cat down-pipe represents exceptional value for any rider who is serious about performance. Lightweight, free-breathing, and British-made — it’s a combination that simply can’t be matched at this price point.

Fitment & Installation Notes for the Benelli TNT125 & TNT135 Tornado +TNT Naked Ø32mm De Cat Down-Pipe

Fitment has been designed to be as straightforward as possible. The benelli tnt125 & tnt135 tornado +tnt naked Ø32mm de cat down-pipe is engineered to fit exactly as the standard OEM downpipe does — using the standard gasket at the header joint and connecting cleanly to the standard rear silencer or aftermarket can. You won’t need to fabricate brackets, modify mounts, or source additional hardware beyond what’s already included in the kit.

The downpipe connects to your standard rear can using the OEM gasket, so if you’re keeping your stock silencer in place, this is a truly plug-and-play upgrade in terms of fitment. We do, however, strongly recommend applying a normal household silicone-based sealant inside any joints before final assembly. This creates a gas-tight seal, prevents any unwanted leaks, and ensures the pipework performs exactly as it should from the very first ride.

The lambda sensor hole comes pre-formed in the pipework, so your OEM standard sensor simply refits into its designated position. There’s no need for additional bungs, adapters, or modifications — it’s ready to accept your sensor straight out of the box.

• Fits: Benelli TNT125, TNT135, Tornado, and TNT Naked models
• Connects directly to the standard rear silencer or aftermarket can
• Uses the standard OEM gasket — no additional gasket purchase required
• Lambda sensor port pre-drilled — refit your OEM sensor without modification
• Apply silicone sealant to all joints for a gas-tight seal
• No fuelling changes required for standard setups — see note below

A Note on Fuelling

Max Torque Cans exhausts are manufactured and tuned to deliver maximum power without requiring any alteration to the standard fuelling map. However, if your Benelli is already running an aftermarket air filter, or if you’re combining the benelli tnt125 & tnt135 tornado +tnt naked Ø32mm de cat down-pipe with an aftermarket performance can, we always recommend having the fuelling reviewed by a competent tuner. Addressing fuelling in combination with free-breathing exhaust upgrades will always complement engine performance and efficiency — and ensure you extract every last drop of potential from your setup.

Why Choose the Benelli TNT125 & TNT135 Tornado +TNT Naked Ø32mm De Cat Down-Pipe From Max Torque Cans?

There are cheaper options out there — we won’t pretend otherwise. But few, if any, are British-made from T304 stainless steel, developed specifically for the Benelli TNT family, and backed by a team that genuinely rides and understands these machines. The benelli tnt125 & tnt135 tornado +tnt naked Ø32mm de cat down-pipe was specifically developed for riders who want a more refined look and a more purposeful sound, without crossing into full race-can territory. It’s the ideal upgrade for daily riders, commuters, and weekend enthusiasts who want something better than stock without compromising road usability.

The Powerbomb baffle gives the exhaust a noticeably improved note — more character, more presence — whilst keeping things within road-legal limits. You get the soundtrack without the anti-social volume. That balance is something we’ve worked hard to achieve, and rider feedback has been overwhelmingly positive. When you bolt on the benelli tnt125 & tnt135 tornado +tnt naked Ø32mm de cat down-pipe, you’ll notice the difference from the moment you fire the engine for the first time.

If you’re exploring de-cat options for other bikes in your garage, take a look at our Aprilia RS660 De-Cat DownPipes — another precision-engineered piece of British craftsmanship delivering the same philosophy of weight reduction, improved gas flow, and real-world performance gains. We also stock the Triumph 765 Moto 2 De-Cat pipe for Triumph riders looking for the same no-compromise approach, and the BSA Gold Star de res pipe 304 Stainless Steel for classic British bike enthusiasts who refuse to settle for anything less than the best.
