New Kawasaki Versys 1000cc 2019-On Stainless De-cat exhaust pipe & clamps

“`html

When it comes to upgrading your Kawasaki Versys 1000, few modifications deliver the impact of premium kawasaki performance superbike exhausts, and this stainless steel de-cat exhaust pipe represents the perfect balance of performance enhancement, weight reduction, and value for money. Designed specifically for the 2019-onwards Kawasaki Versys 1000cc models, this precision-engineered component transforms your bike’s exhaust system by eliminating the restrictive factory catalytic converter box whilst maintaining complete compatibility with both OEM and aftermarket rear silencers.

Why Choose Kawasaki Performance Superbike Exhausts De-Cat Systems

The factory catalytic converter fitted to your Kawasaki Versys 1000 serves an environmental purpose, but it comes at a significant cost to performance, weight, and aesthetics. Weighing in at a substantial 5.0 kilograms, the standard cat box is not only heavy but also creates measurable restriction in your exhaust flow. By replacing it with this premium de-cat pipe, you’ll immediately shed 4.3 kilograms from your motorcycle—that’s a remarkable weight saving that enhances handling, acceleration, and overall rideability.

This replacement pipe is manufactured from high-grade T304 stainless steel, renowned throughout the automotive and motorcycle industries for its exceptional corrosion resistance, durability, and ability to withstand extreme temperatures without discolouration or degradation. The 50mm diameter tubing has been CNC mandrel-bent to ensure smooth, consistent internal diameter throughout every curve and bend, eliminating the internal ridges and restrictions that plague cheaper crush-bent alternatives.

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

Your complete kit includes everything necessary for installation:

• One precision CNC mandrel-bent 50mm diameter T304 stainless steel de-cat link pipe
• High-quality stainless steel clamps for secure, leak-free fitment
• Detailed fitting instructions with photographs showing exact cutting positions
• Technical support via our installation guides and video demonstrations

The beauty of this system lies in its simplicity. Unlike some aftermarket exhaust modifications that require expensive professional welding or complex fabrication, this de-cat pipe uses a straightforward clamp-fit design. Your existing OEM headers require cutting at the specified position (clearly illustrated in our comprehensive fitting guide), after which the new de-cat pipe slots into place and secures firmly with the supplied clamps.

No welding equipment needed, no specialised tools beyond standard workshop items, and no permanent modifications that can’t be reversed if required.

Performance Benefits of Kawasaki Performance Superbike Exhausts Upgrades

Removing the catalytic converter delivers tangible performance improvements across the rev range. The standard cat box creates backpressure that inhibits exhaust gas flow, particularly at higher RPMs where your engine is trying to expel larger volumes of spent gases. By eliminating this restriction, your Versys 1000’s engine can breathe more freely, resulting in improved throttle response, slightly increased power output, and a more engaging exhaust note that better reflects the character of Kawasaki’s potent parallel-twin powerplant.

The 4.3-kilogram weight reduction might seem modest on paper, but remember that this is unsprung weight removed from the exhaust system. Every gram saved here contributes to improved handling dynamics, reduced inertia, and enhanced agility through corners. For riders who enjoy spirited riding on twisty roads or occasional track days, this weight saving delivers noticeable benefits.

Additionally, if you’re running an aftermarket exhaust system or planning future modifications, this de-cat pipe provides an excellent foundation. Many aftermarket silencers are designed to work optimally with free-flowing headers and link pipes, and removing the restrictive factory cat box allows these systems to perform as intended. Whether you’re fitting a Carbon Can Co slip-on or another manufacturer’s full system, this de-cat pipe ensures maximum flow efficiency.

Installation and MOT Considerations for Kawasaki Performance Superbike Exhausts

Installation is classified as a workshop-level job, though competent home mechanics with appropriate tools and mechanical experience should find it manageable. You’ll need an angle grinder or pipe cutter to remove the factory cat box at the designated cutting points, plus basic hand tools to fit the clamps and secure the new pipe. The entire process typically takes 2-3 hours for someone with reasonable mechanical aptitude.

An important consideration for UK riders concerns MOT compliance. Motorcycles registered after 2009 are subject to noise testing during MOT inspections, but unlike cars, they are not currently subjected to emissions testing. This means that provided your exhaust system remains roadworthy and doesn’t exceed legal noise limits (typically achieved by retaining a road-legal silencer), your Versys should continue to pass MOT inspections even with the catalytic converter removed.

However, regulations do change, so we always recommend checking current MOT requirements before making modifications.

For riders seeking similar upgrades for other Kawasaki models, Carbon Can Co offers an extensive range. The Kawasaki Z1000 2010-2019 single right hand CNC Stainless De-cat pipe & clamps provides comparable benefits for Z1000 owners, whilst those with H2 models might explore our Stainless exhaust pipe & clamp for Kawasaki H2 SE & SX with ZX10R Headers.

Frequently Asked Questions

Will this fit my aftermarket exhaust?
Yes, this de-cat pipe works with both OEM and aftermarket rear silencers. It replaces only the catalytic converter section, leaving your existing silencer mounting points unchanged.

Do I need to remap my ECU after fitting?
Whilst not strictly essential, an ECU remap or fuel controller can optimise your engine’s fuelling to take full advantage of the improved flow characteristics. Many riders notice improved performance even without remapping, though professional tuning extracts maximum benefit.

How durable is T304 stainless steel?
T304 grade stainless is the industry standard for quality exhaust systems, offering excellent resistance to corrosion, heat discolouration, and the rigours of daily riding. It will outlast mild steel alternatives many times over.

Can I reverse this modification?
Because the installation requires cutting your OEM headers, the modification isn’t directly reversible. However, replacement OEM headers are available if you need to return the bike to stock specification in future.

This Kawasaki Versys 1000 de-cat pipe represents exceptional value for riders seeking proven performance enhancement without the premium price tag of full exhaust systems. With significant weight savings, improved flow characteristics, and straightforward installation, it’s an upgrade that delivers tangible benefits every time you ride.
