Kawasaki H2 SE & H2 SX 2018 – 2024 Stainless De-cat exhaust pipe CNC Mandrel bent C/W clamp

The kawasaki h2 se & h2 sx 2018 – 2024 stainless de-cat exhaust pipe cnc mandrel bent c/w clamp is, quite simply, one of the most rewarding bolt-on upgrades you can make to your supercharged H2 — delivering a genuine weight saving, improved gas flow, and a cleaner mid-section aesthetic, all without the need for welding or specialist tooling. If you own a Kawasaki H2 SE or H2 SX built anywhere between 2018 and 2024 and you’ve been searching for a no-nonsense way to ditch that heavy, cumbersome factory catalytic converter, this is exactly the product your bike has been waiting for. Manufactured from premium T304 stainless steel and precision CNC mandrel bent to a 60mm diameter, it’s engineered specifically around your machine’s OEM dimensions and fits with confidence, right first time.

Why the Kawasaki H2 SE & H2 SX 2018 – 2024 Stainless De-Cat Exhaust Pipe CNC Mandrel Bent C/W Clamp Makes Such a Difference

The factory catalytic converter fitted to the H2 SE and H2 SX is a substantial piece of kit — and not in a flattering way. Tipping the scales at a considerable 3.9 kg, the standard cat box is heavy, bulky, and genuinely restrictive in terms of exhaust gas flow. The kawasaki h2 se & h2 sx 2018 – 2024 stainless de-cat exhaust pipe cnc mandrel bent c/w clamp replaces that cumbersome unit with a svelte, precision-engineered link pipe weighing just 1.2 kg. That’s a saving of 2.7 kg of centralised mass removed from the very heart of the machine — and on a motorcycle that already delivers breathtaking, supercharged performance, shedding dead weight from the mid-section translates into a genuinely noticeable improvement in handling feel and throttle response.

Beyond the raw weight saving, the smooth CNC mandrel bent bore ensures exhaust gases flow freely and consistently from your headers rearward to your chosen silencer. Mandrel bending preserves the pipe’s internal diameter throughout every curve, eliminating the crushed or pinched sections that are common with cheaper pressed or crush-bent alternatives. The result is improved scavenging, sharper throttle pickup, and a more satisfying exhaust note — whether you’re retaining the standard rear silencer or you’ve already upgraded to a quality aftermarket performance can.

Fitment and Installation — Getting the Kawasaki H2 SE & H2 SX 2018 – 2024 Stainless De-Cat Exhaust Pipe CNC Mandrel Bent C/W Clamp Fitted

One of the most appreciated qualities of this product is just how straightforward the installation process is. The kawasaki h2 se & h2 sx 2018 – 2024 stainless de-cat exhaust pipe cnc mandrel bent c/w clamp is designed to slot directly into the space currently occupied by your factory cat box. Remove the standard unit, offer up the new de-cat link pipe in its place, and secure everything using the supplied clamp. There is absolutely no welding required at any stage — a standard set of workshop spanners is all you need to complete the job.

The pipe retains your existing oxygen sensor location within the front downpipes, meaning the bike’s fuelling and engine management continues to operate as intended straight out of the box. You won’t need to re-jet, remap, or make any software changes simply to fit this pipe — it functions as a true direct replacement for the factory catalytic converter. Whether your rear silencer is the original Kawasaki unit or an aftermarket performance can you’ve already invested in, this de-cat pipe accommodates both with ease. The rear connection dimensions mirror the original fitment, so your silencer bolts back up exactly as it did before.

For best results, fit the pipe with the engine cold and torque all clamp connections properly before starting the bike. A brief heat cycle after installation will allow the T304 stainless steel to settle naturally, and a quick re-check of the clamp after your first ride is always sensible practice.

MOT and Road Legality — What UK Riders Need to Know

This is a point that catches many riders off guard — and it’s largely good news. In the United Kingdom, motorcycles are assessed for noise during the MOT inspection, not emissions. This means that provided your rear silencer is road-legal and within the permitted noise limits, removing the factory catalytic converter box with the kawasaki h2 se & h2 sx 2018 – 2024 stainless de-cat exhaust pipe cnc mandrel bent c/w clamp will not in itself cause your machine to fail its MOT. If you’re running a compliant aftermarket performance can, you can fit this de-cat pipe and ride to the test centre with a clear conscience.

Please note that this product is intended for closed-road or competition use in jurisdictions where the removal of emissions equipment is prohibited for road use. Always check your local regulations and use responsibly. For the overwhelming majority of UK riders who simply want a lighter, freer-flowing mid-section without drama, this is a brilliantly practical and cost-effective solution.

Do I need to remap the bike after fitting?

In most cases, no. Because the O2 sensor remains in the front downpipes as standard, the ECU continues to read fuelling data as normal.
