Stainless exhaust pipe & clamp for Kawasaki H2 SE & SX with ZX10R Headers

When it comes to upgrading kawasaki performance superbike exhausts, riders of the H2 SE and SX models have long searched for a solution that delivers weight savings, performance gains, and improved aesthetics without compromising on quality or legality. Carbon Can Co Ltd is proud to offer this precision-engineered stainless steel de-cat exhaust pipe and clamp kit, specifically designed to work with Kawasaki ZX10R titanium headers on H2 SE and SX models.

This innovative solution eliminates the restrictive factory catalytic converter assembly, transforming your superbike’s exhaust system whilst maintaining excellent build quality and fitment.

Why Choose This Kawasaki Performance Superbike Exhausts Upgrade

The factory catalytic converter assembly on the Kawasaki H2 SE and SX models is a substantial unit weighing in at 3.9 kilograms. It’s bulky, visually unappealing, and creates a significant restriction in your exhaust flow. Our CNC mandrel-bent 60mm diameter link pipe addresses all these issues in one elegant solution. Manufactured from high-grade T304 stainless steel, this de-cat pipe weighs just 1.0 kilogram, delivering an impressive weight saving of 2.9 kilograms from your motorcycle.

For a performance superbike where every gram counts, this reduction in unsprung mass improves handling characteristics, acceleration response, and overall riding dynamics.

The precision CNC mandrel bending process ensures consistent internal diameter throughout the pipe’s length, maintaining optimal exhaust gas flow without the turbulence that crush-bent alternatives create. This manufacturing technique is essential for kawasaki performance superbike exhausts, where exhaust velocity and scavenging efficiency directly impact power delivery across the rev range. The smooth internal surface reduces back pressure, allowing your H2’s supercharged engine to breathe more freely and deliver the explosive performance these machines are renowned for.

Complete Kawasaki Performance Superbike Exhausts Installation Kit

What sets this product apart is the comprehensive, installation-ready package. You receive everything needed to complete the conversion: the T304 stainless steel de-cat pipe itself, plus a high-quality stainless steel clamp for secure, leak-free connection. Unlike some aftermarket solutions that require professional welding or modification, this system is designed for straightforward installation.

The pipe connects directly to Kawasaki ZX10R titanium headers at the front, and your existing rear silencer—whether standard or aftermarket—at the rear. This means you can retain your current exhaust can whilst gaining all the benefits of catalytic converter removal.

The beauty of this design lies in its versatility and simplicity. Whether you’re running the original Kawasaki exhaust silencer or have already upgraded to an aftermarket carbon or titanium system, this de-cat pipe integrates seamlessly. The 60mm diameter is carefully calculated to match the flow characteristics of the ZX10R headers whilst providing optimal gas velocity for the H2’s displacement and power output.

The included clamp is manufactured to the same exacting standards as the pipe itself, ensuring a secure, vibration-resistant connection that will withstand the rigours of high-performance riding.

Understanding De-Cat Benefits for Kawasaki Performance Superbike Exhausts

Catalytic converters serve an important environmental function, but they inevitably create exhaust restriction. For track-focused riders or those seeking maximum performance from their H2 SE or SX, removing this restriction unlocks noticeable gains. You’ll experience sharper throttle response, particularly in the mid-range where the supercharger is building boost. The reduced back pressure allows exhaust gases to exit more efficiently, improving engine breathing and potentially adding several horsepower at the wheel.

Additionally, many riders report a more aggressive exhaust note—deeper and more mechanical-sounding without the muffling effect of the catalytic substrate.

The weight saving cannot be overstated. Removing nearly three kilograms from the exhaust system lowers the motorcycle’s centre of gravity and reduces overall mass. This translates to quicker direction changes, improved suspension performance, and reduced fatigue during spirited riding. For track day enthusiasts, every advantage counts, and this modification delivers tangible improvements you’ll feel immediately.

Similar benefits can be found across other models in our range, such as our Kawasaki Z1000 2010-2019 single right hand CNC Stainless De-cat pipe, which offers comparable performance enhancements for that popular naked bike platform.

Legal Considerations and MOT Compliance

An important consideration for UK riders is MOT compliance. Unlike cars, motorcycles registered after specific dates are tested for noise emissions rather than exhaust gas emissions during MOT testing. This means that if you retain a road-legal exhaust silencer that passes the noise test—whether standard or an approved aftermarket unit—your motorcycle can still pass its MOT even with the catalytic converter removed.

However, riders should always verify current regulations and ensure their complete exhaust system meets legal requirements for road use. For track-only machines, this consideration is naturally irrelevant, and you’re free to optimise purely for performance.

It’s worth noting that this listing is for the de-cat pipe and clamp only—the Kawasaki ZX10R titanium headers are sold separately and must be sourced independently. These headers are a popular upgrade in the H2 community due to their significant weight savings over the standard stainless steel items.

When combined with this de-cat pipe, you create a comprehensive front-to-mid exhaust upgrade that transforms both the performance and appearance of your H2 SE or SX. For riders considering similar upgrades on other Kawasaki models, our Kawasaki ZR900RS Cafe de-cat exhaust pipe offers an equally refined solution for that retro-styled machine.

Installation and Fitment

The installation process is refreshingly straightforward, especially compared to custom fabrication alternatives. Once you’ve installed your ZX10R titanium headers in place of the factory H2 items, this de-cat pipe simply connects between the headers and your existing rear silencer. The precision CNC manufacturing ensures exact fitment without any adjustments or modifications required.

The supplied clamp provides sufficient clamping force to create a gas-tight seal whilst allowing for the thermal expansion that occurs during operation. Most experienced home mechanics can complete this installation with basic hand tools in under an hour.

For those less confident with mechanical work, any competent motorcycle workshop will be familiar with this type of installation. The straightforward design means labour costs remain minimal. Once installed, the system requires no special maintenance beyond occasional inspection of the clamp tightness—a sensible practice for any exhaust connection point. The T304 stainless steel construction offers excellent corrosion resistance, ensuring the pipe maintains its appearance and structural integrity through years of use, even in challenging British weather conditions.

Technical Specifications and Quality Assurance

Carbon Can Co Ltd manufactures this de-cat pipe to exacting standards. The T304 stainless steel grade offers the optimal balance of strength, corrosion resistance, and weldability. This austenitic chromium-nickel alloy contains approximately 18% chromium and 8% nickel, providing excellent resistance to atmospheric corrosion and oxidation at the elevated temperatures exhaust systems experience.

The CNC mandrel bending process maintains consistent 60mm internal diameter throughout all bends, preventing the wall thinning and flow disruption that occurs with cheaper crush-bent alternatives. Each pipe undergoes quality inspection before shipping to ensure it meets our specifications for dimensional accuracy and surface finish.
