Kawasaki KLZ Versys 1000 2012 – 2019 Stainless De-cat exhaust pipe & clamps

When it comes to upgrading your motorcycle’s exhaust system, few modifications deliver the same combination of weight savings, performance gains, and enhanced sound as high-quality kawasaki performance superbike exhausts, and this precision-engineered de-cat pipe for the Kawasaki KLZ Versys 1000 (2012-2019) represents outstanding value for riders seeking to unlock their bike’s true potential.

Premium Kawasaki Performance Superbike Exhausts: Versys 1000 De-Cat System

This professional-grade stainless steel de-cat exhaust pipe has been specifically designed for the Kawasaki KLZ Versys 1000 models manufactured between 2012 and 2019. Constructed from premium T304 stainless steel using CNC mandrel bending technology, this 50mm diameter link pipe replaces your restrictive factory catalytic converter box with a free-flowing alternative that dramatically reduces weight whilst improving exhaust gas flow.

The factory catalytic converter on your Versys 1000 weighs a substantial 4.2 kilograms, whereas this aftermarket de-cat pipe weighs just 0.5 kilograms. That’s an impressive weight saving of 3.7 kilograms from a single component replacement—weight reduction that you’ll notice in improved handling, acceleration, and overall rideability. For adventure touring riders who value every kilogram when fully loaded, this modification makes genuine practical sense.

What’s Included with Your Kawasaki Performance Superbike Exhausts De-Cat Kit

Your complete de-cat system arrives ready to install and includes everything necessary for a professional finish:

• One CNC mandrel-bent 50mm diameter T304 stainless steel link pipe, precision-manufactured to exact specifications
• High-quality stainless steel exhaust clamps for secure, leak-free installation
• Comprehensive fitting instructions with photographs showing exact cut positions
• Full technical support from Carbon Can Co Ltd’s experienced team

The T304 grade stainless steel construction ensures exceptional corrosion resistance and longevity, even in the harshest riding conditions. Unlike mild steel alternatives that rust and discolour within months, this premium material maintains its appearance and structural integrity for years of reliable service.

Installation and Compatibility for Kawasaki Performance Superbike Exhausts

This de-cat pipe is designed as a direct replacement for your standard catalytic converter box, fitting between your OEM or aftermarket headers and your rear silencer. Installation requires cutting your standard headers at the specified position (detailed photographs and instructions are provided via our Flickr album and YouTube installation video), then connecting the new de-cat pipe using the supplied clamps. No welding is required, making this a straightforward bolt-on modification.

The beauty of this system lies in its versatility—your rear silencer can remain completely standard, or you can run any aftermarket end can. The de-cat pipe integrates seamlessly with either configuration, maintaining proper fitment whilst eliminating the bulky, restrictive catalytic converter that inhibits your Versys 1000’s performance potential.

While this is typically considered a workshop job, any competent, mechanically-minded rider with basic tools and workshop facilities should be capable of completing this installation. The process involves measuring, marking, cutting, and clamping—no specialist equipment or welding skills necessary.

Performance Benefits and Legal Considerations

Removing the restrictive catalytic converter delivers noticeable improvements across the rev range. You’ll experience crisper throttle response, enhanced mid-range torque delivery, and a more characterful exhaust note that better suits the Versys 1000’s willing engine character. The improved exhaust gas flow allows your engine to breathe more efficiently, particularly when paired with appropriate fuelling adjustments or ECU mapping.

Regarding MOT testing in the UK, it’s worth noting that motorcycles are subject to noise testing rather than emissions testing during standard MOT inspections. Therefore, provided you retain a road-legal silencer that meets noise regulations, your Versys 1000 should pass its MOT even with the catalytic converter removed. However, riders should be aware of current legislation and ensure compliance with all applicable regulations.

For the most current information on vehicle emissions standards and testing requirements, consult the official UK Government MOT guidance.

Frequently Asked Questions

Will this fit aftermarket headers?
This de-cat pipe is designed specifically for OEM Kawasaki KLZ Versys 1000 headers. Fitment with aftermarket headers cannot be guaranteed without specific measurements and may require custom modification.

Do I need to remap my ECU after installation?
While not strictly essential, ECU remapping or fuelling adjustment is recommended to fully exploit the improved exhaust flow and optimise performance across the rev range. Many riders report improved results when pairing de-cat pipes with appropriate fuelling modifications.

How does the sound change after removing the catalytic converter?
Expect a deeper, more characterful exhaust note with enhanced mechanical sounds from the engine. The change is noticeable but not excessively loud, particularly when retaining a standard or road-legal aftermarket silencer.

What tools will I need for installation?
You’ll require a cutting tool suitable for stainless steel (angle grinder or reciprocating saw), measuring tape, marker pen, basic spanners or sockets for clamp installation, and appropriate safety equipment including eye protection and gloves.
