Honda Monkey Z125cc Performance Exhaust Muffler & System

The honda monkey z125cc performance exhaust muffler & system from Max Torque Cans is, without question, one of the most satisfying and rewarding bolt-on upgrades you can make to the Honda Monkey 125 — a beautifully crafted, British-made combination of a T304 stainless steel front pipe and a Mini Oval silencer that transforms the way your bike looks, sounds, and pulls through the rev range. If you have been searching for a quality performance can built to last, tuned for genuine real-world gains, and finished to a standard that truly complements the iconic Honda Monkey aesthetic, you have arrived at exactly the right place.

Why the Honda Monkey Z125cc Performance Exhaust Muffler & System Is the Upgrade Your Monkey Deserves

The Honda Monkey is a machine absolutely dripping with personality — but the stock exhaust does precious little to express it. Restrictive, heavy, and uninspiring in both sound and finish, the standard setup holds this feisty little bike back from what it is genuinely capable of. Our honda monkey z125cc performance exhaust muffler & system changes all of that, delivering a meaningful mechanical improvement wrapped in a premium British finish that looks every bit as good as it performs.

Manufactured right here in Britain using T304 stainless steel throughout, this performance can is engineered to withstand year-round riding conditions without complaint. T304 stainless offers outstanding resistance to corrosion and holds its finish far longer than the cheaper mild steel or low-grade alternatives commonly found on imported units. Whether you are threading through city traffic on the daily commute or making the most of a clear weekend road, this performance can delivers consistently and without compromise.

The performance gains come from a fundamentally improved approach to exhaust gas flow. The standard header on the Monkey 125 is a restriction by design — built to pass emissions regulations and keep production costs down, not to optimise power delivery. Our bespoke stainless steel front pipe allows exhaust gases to exit far more freely and efficiently, translating directly into sharper throttle response and a noticeable uplift in mid-range pull. Combine that with the removal of the restrictive standard cat box, and you will feel the difference from the very first ride.

What’s Included With Your Honda Monkey Z125cc Performance Exhaust Muffler & System

When your order arrives, you will have everything needed to get fitted and back on the road without delay. The kit contains a British-made T304 stainless steel front pipe and header, paired with a Mini Oval silencer in your chosen finish. The silencer comes complete with a dedicated fitting bracket and strap to ensure solid, vibration-free mounting at the rear of the bike. The front pipe is designed to replicate the routing and fitment points of the standard unit exactly, so there is no hunting around for specialist hardware or obscure adaptors.

We supply the honda monkey z125cc performance exhaust muffler & system as a complete, cohesive solution — every component designed and manufactured to work in harmony. The front pipe mates directly to the engine using the existing OEM gasket, saving time during installation and ensuring a proper, gas-tight seal from the outset. A standard silicone-based household sealant applied at the joins completes the setup, keeping everything sealed and performing exactly as it should for miles to come.

One important recommendation: for the best possible results, remove the standard cat box when fitting this performance can. The cat box is one of the single largest restrictions in the standard Honda Monkey setup, and eliminating it allows the improved pipework to deliver its full potential in terms of gas flow, throttle response, and power output. It is the single biggest difference you can make alongside fitting the new front pipe, and we strongly encourage every customer to do it.

Fitting Guide for the Honda Monkey Z125cc Performance Exhaust Muffler & System

Fitting the honda monkey z125cc performance exhaust muffler & system is comfortably within the reach of any mechanically competent rider working with a basic set of hand tools. The front pipe replicates the standard routing precisely, removing any guesswork from the installation and keeping the job clean and manageable. Here is a straightforward overview of what is involved:

• Remove the stock exhaust carefully, retaining the OEM gasket for reuse during refitting
• Remove the standard cat box to unlock the full performance potential of the new pipework
• Fit the new stainless steel front pipe using the OEM gasket — check alignment carefully before tightening fasteners
• Apply a silicone-based household sealant at all joins to achieve a secure, gas-tight connection throughout
• Mount the Mini Oval silencer using the supplied bracket and strap, ensuring it is firmly secured before the bike is ridden
• Allow the sealant to cure fully as per the manufacturer’s instructions before starting the engine

The process is straightforward, but if you have any doubt about carrying out the work yourself, we would always recommend having the fitting completed by a qualified workshop. A competent home mechanic, however, should find the whole job entirely manageable across a single afternoon. The results are genuinely rewarding — a sharper, more responsive Honda Monkey that sounds and performs the way it always should have done.

If you ride other machines alongside your Monkey and want the same quality of British craftsmanship throughout your garage, our Honda CB1000R SC80 2018- 2024 performance can is an outstanding choice for riders stepping up to a larger Honda. The same commitment to T304 stainless steel and British manufacturing runs through everything we make at Max Torque Cans.
