The kawasaki z400 abs 2021 is one of the most exciting naked middleweights on the market, and if you’re looking to unlock its full potential, fitting a quality performance exhaust is one of the smartest upgrades you can make. At Max Torque Cans, we’ve developed a bolt-on exhaust specifically designed to complement the kawasaki z400 abs 2021, delivering an aggressive exhaust note, a cleaner aesthetic, and a fitment that requires zero modifications to your standard OEM downpipes.
Why Upgrade the Exhaust on Your Kawasaki Z400 ABS 2021?
The kawasaki z400 abs 2021 already punches well above its weight class straight from the factory, but the stock silencer is designed with noise regulations and mass-market appeal in mind — not outright performance character. Swapping it out for a Max Torque Cans performance exhaust transforms the riding experience. You’ll notice an immediate improvement in exhaust tone, giving the kawasaki z400 abs 2021 a deeper, more purposeful sound that matches its aggressive naked styling.
Beyond the sound, a lighter aftermarket can reduces unsprung weight at the rear of the bike, which can sharpen handling response and improve the overall riding dynamic. Whether you’re carving up country roads, commuting with attitude, or heading to a trackday, the right exhaust makes every ride feel more rewarding.
What’s Included with This Kawasaki Z400 ABS 2021 Exhaust?
We believe in making your upgrade as straightforward as possible. Every kawasaki z400 abs 2021 exhaust from Max Torque Cans comes complete with everything you need to get it fitted and on the road quickly. The kit includes:
- 1 x Performance Exhaust Can — precision engineered to suit the kawasaki z400 abs 2021
- 1 x Stainless Exhaust Strap — durable, corrosion-resistant and built to last
- 1 x Exhaust Strap Rubber — protects the fitment and absorbs vibration
- 3 x Bolt-On Fixings — everything you need for a secure, rattle-free install
There’s nothing worse than receiving a performance upgrade only to find you need to source additional hardware before you can fit it. We’ve made sure that every kawasaki z400 abs 2021 kit from Max Torque Cans is complete straight out of the box.
Direct Bolt-On Fitment for the Kawasaki Z400 ABS 2021
One of the standout features of this exhaust is how clean and simple the installation process is. This performance can is designed to bolt directly onto the standard OEM downpipes of the kawasaki z400 abs 2021 — no cutting, no welding, no specialist tools required. If you’re confident with basic spanner work, this is a job you can comfortably carry out at home in your garage.
The 3-bolt fitting ensures a solid, vibration-free connection to the downpipe, while the stainless exhaust strap and rubber provide secure rear mounting that keeps the can firmly in position under hard acceleration and over rough road surfaces. The result is a fitment that looks factory-clean and performs brilliantly.
We always recommend allowing the exhaust to cool completely before handling, and to carry out a quick check of all fixings after your first few rides, as components can settle slightly during initial heat cycling. Other than that, your kawasaki z400 abs 2021 is ready to roar.
Installation Tips for Your Kawasaki Z400 ABS 2021 Performance Can
Getting the most from your new exhaust starts with a clean, careful installation. Here are a few practical tips to ensure the best result on your kawasaki z400 abs 2021:
- Let the bike cool down — always work on a cold engine to avoid burns and to get accurate fitment without thermal expansion affecting joint tightness.
- Use copper anti-seize on the bolt threads — this makes future removal far easier and prevents corrosion locking the bolts in place over time.
- Check alignment before fully tightening — loosely fit all three bolts and the rear strap first, then check the can sits level and central before torquing everything down.
- Run through a heat cycle before riding hard — start the bike, let it reach operating temperature, then allow it to cool completely before pushing it. This settles all the joints and fixings properly.
- Re-check all fixings after 100 miles — a quick once-over ensures everything remains tight and secure as the exhaust settles into its final position.
If you’d prefer to see the full installation process in action, we’ve filmed detailed fitting videos for the kawasaki z400 abs 2021 which you can find on the Max Torque Cans YouTube channel. Watching a real-world fitment walkthrough is the best way to build confidence before you crack out the spanners.

Yes — this performance can is designed to bolt straight onto the OEM downpipes of the kawasaki z400 abs 2021 with no cutting, welding, or modifications whatsoever. It’s a true bolt-on upgrade.

Please check with your local regulations and insurer before use on public roads. We recommend verifying noise and emissions compliance for your specific use case.
How do I maintain my new exhaust?
Regular cleaning with a mild, exhaust-safe cleaner will keep your can looking sharp. Avoid harsh chemicals on stainless or carbon finishes, and periodically check all fixings for tightness, particularly after spirited riding sessions.
