Have a few simple additions, but as we all know this bike is ridiculously quiet. Any options to give it a set of balls/find its voice? Looking for a slip on exhaust setup if possible

The factory exhaust is 1 piece, so you won't find just a slip on muffler. Lots of aftermarket full exhausts, and most of those come in 2 pieces with the muffler detachable from the exhaust header pipe. One thing I recommend you look out for is the attachment points. Ideally it should have rubber isolated mounting tabs and/or re-use the factory 3 point mount (cylinder head, bolt above the rear brake cylinder cover, and rear shock mount). The reason I mention this is that some aftermarket exhausts that might not be well supported could result in breaking the frame at the shock mount. It's happened more than once.

I have an Outex exhaust on mine and purchased an additional support for it (required some modification with my exhaust crash guard). The Outex setup is not quiet. You can no longer ride the bike stealthily and it attracts attention. I have the factory exhaust on my Dax and it sometimes finds itself in (empty) pathways, bridges, off-road shortcuts, and areas where motor vehicles are prohibited. Because nobody hears it, there's no trouble. Wouldn't risk the same with the louder CT and its aftermarket exhaust. Just something to consider, especially if you're a hooligan or appreciate being on good terms with the neighbors.

Hi mate,

I just fitted this https://www.yoshimura-jp.com/product/n-121298?lang=en on my 2024 Ct125

Its not a slip on, but the complete system. the loudness is perfect. louder than stock, sounds really nice under load. kinda like " look at me" and not "LOOOOOOKK AT MEEEEE" View attachment 13898


downside is yes its expensive, but i feel it was 100% worth it.
I just fitted the same system to my 2025. Looks great and has the perfect sound without being loud.

I have done some scientific testing of my Yoshi Tactical addition. On a flat, calm straight section of road. Top speed has increased 2mph, 59 mph to 61 mph indicated. Quite impressive.
