The first upgrade in my ownership of a delightful 2023 Honda Monkey Bike (Z125) is the Takegawa (Standard Look) Aftermarket exhaust that eliminates the catalytic converter and gives her a little bit noise to sound more like a monley bike should.
This exhaust was purchased from "Ben's Bikes Racing" in the UK and delivery was fast to the Isle of Man and the item was very well packaged. It is available to buy from his website here.....

Here are the fitting insructions for the exhaust as I translated the original Japanese instruction manual from Takegawa:
1. Remove the black plastic end cap from the exhaust muffler, which is held on by 3 x 5mm Allen head bolts.
2. Remove the chrome heat shield - 2 x 5mm allen head bolts
3. Remove the 2 x mounting bolts (12mm hex head) that secure the muffler to the bike frame
4. Loosen the exhaust band bolt (12mm hex head) and then hold the muffler and rotate it away from the bike and remove it from the pipe still attached to the engine
5. Remove the 12mm mounting bolts securing the exhaust stay bracket underneath the engine
6. Remove the 2 x exhasut manifold nuts (8mm) and remove the stock exhaust pipe and the ring gasket, which will be quite stuck in place
7. Install the new downpipe and gasket and loosely by hand, secure the two exhaust manifold nuts but don't tighten them yet
8. Swap all of the rubber grommets and rubbers from the original exhaust to the new Takegawa exhaust muffler
9. Remove and swap the exhaust protector (5mm allen bolts) from the original to the new exhaust downpipe
10. When fitting the muffler gasket and securing band, it is recommended to apply heat-resistant gasket sealant to the inside and outside of the ring gasket. I used Dirko HT grey, which is good for 300 degrees celsius temperatures and it is available here: [ Ссылка ]
11. Insert the ring gasket into the muffler pipe and loosely fit the band around the gasket
12. Fit the muffler into the downpipe and then secure the muffler to the mounting frame with the 2 x 12mm hex head bolts
13. Then tighten the band bolt for the muffler to ensure a good seal between the downpipe and muffler
14. Tighten the two exhaust manifold nuts (8mm) to a recommended torque of 16 to 17 Nm
15. Refit the chrome exhaust shield making sure it is seated on the three mounting points and rubber correctly. It just slides on from the back of the bike to the front
16. Refit the muffler end cap (3 x 5mm allen head bolts) and then start the engine and check for any leaks and enjoy!
