When it comes to upgrading your motorcycle with benelli performance superbike exhausts, the New Benelli TNT125 & 135 Tornado+Naked De Cat Down-Pipe Exhaust Header represents the pinnacle of British engineering and craftsmanship. Manufactured right here in the UK from premium T304 stainless steel, this Ø32mm header system has been meticulously designed to deliver enhanced performance, significant weight savings, and a refined exhaust note that sits perfectly within road-legal limits whilst giving your Benelli the soundtrack it deserves.

Premium UK-Made Benelli Performance Superbike Exhausts Engineering

Our British-manufactured downpipe header is precision-engineered specifically for the Benelli TNT125 and TNT135 models, including both the Tornado and Naked variants. Constructed from high-grade T304 stainless steel, this exhaust component offers exceptional durability and corrosion resistance that will withstand years of demanding use. The Ø32mm diameter has been carefully calculated to optimise exhaust gas flow, significantly improving upon the restrictive characteristics of the original equipment manufacturer (OEM) catalytic converter system.

What makes this header truly exceptional is the integrated Powerbomb baffle technology. This innovative feature creates a carefully tuned exhaust note that’s noticeably more spirited than the standard system, yet remains compliant with UK road regulations. The fitting bracket ensures secure mounting, whilst the pre-drilled Lambda sensor hole means you can retain full compatibility with your motorcycle’s oxygen sensor and engine management system without any modifications or warning lights on your dashboard.

Significant Performance and Weight Benefits with Benelli Performance Superbike Exhausts

One of the most impressive aspects of this upgrade is the dramatic weight reduction. The standard Benelli downpipe weighs a hefty 3.4 kilograms, whilst our performance replacement tips the scales at just 1.4 kilograms – delivering an outstanding 2.0 kilogram weight saving. This reduction in unsprung and overall mass contributes to improved handling characteristics, sharper throttle response, and enhanced acceleration across the rev range.

Beyond weight savings, the de-cat design removes the restrictive catalytic converter, allowing exhaust gases to exit the combustion chamber with far less resistance. This improved gas flow translates directly into measurable power gains throughout the powerband. According to research from Motorcycle News, aftermarket exhaust systems can typically deliver between 5-10% power increases on small to medium displacement motorcycles, alongside improvements in throttle response and overall engine refinement.

Installation and Compatibility Details

The header pipe is designed as a direct replacement for your standard Benelli TNT125 or TNT135 front pipe, fitting exactly as the original equipment with no modifications required. It connects seamlessly to your existing rear silencer using the standard mounting points and OEM gasket, ensuring a straightforward installation process that most home mechanics can accomplish with basic tools.

We strongly recommend applying a thin bead of household silicone-based sealant to all joint interfaces before final assembly. This creates a gas-tight seal that prevents exhaust leaks and ensures optimal performance. The Lambda sensor hole is pre-positioned to accept your original oxygen sensor, maintaining full compatibility with your motorcycle’s fuel injection and emissions monitoring systems.
