A lot of people on the Facebook group often ask what the first modification they should make is… and my answer is the exhaust!
While not totally CARB compliant, a new exhaust will quite literally breathe new life into your bike. Considering its small displacement and excellent gas mileage, I think the overall environmental impact may be easier to live with. That’s a decision you need to make.
Where do I get one?
The good news is, this is by far the easiest of the KPM modifications to find. A fellow rider once requested a factory start producing them to the KPR 200’s specs, and considering how prevalent these bikes are pretty much everywhere, but especially in China, a new exhaust can be easily acquired.
Stock Exhaust Stats
Pre-cat pipe size: 35mm OD
Cat area pipe size: 44mm OD
Post cat pipe size: 35mm OD
Your first stop should be eBay. There are literally dozens of listings for KPM 200 and KPR 200 replacement exhaust setups. Most include a space for the stock oxygen sensor. All include a slip-on of some type or another at the end.
They range in price and shipping cost, and some even ship from the U.S. on occasion. The top one in the image at right is what I purchased, albeit with an all-metal looking can at the end.
Installation is fairly simple and straightforward. Starting at the engine, remove all the nuts holding the stock exhaust on the bike. Then, add the replacement pipe and end with the strap that holds on the muffler itself.
The replacement exhausts don’t have as many bracket mounting points as the stock exhaust had, but considering how light these exhaust systems are, the additional support may not be needed. You can always fashion some sort of bracket if you feel so inclined.

Folks should be aware that you will need to replace the exhaust header gasket when replacing the exhaust. You will need a 40mm OD gasket which you can find on Amazon. Cyclegear and other auto parts stores do not carry in store, so you’ll need to order ahead of time.
