YOXUFA Exhaust Pipe Muffler Silencer Assembly for 2-Stroke Motorized Bike Bicycle 100cc 80cc 66cc 50cc 49cc BT80 YD100 Motor Engine Heavy Duty Parts Black

I have only used the stock exhaust for my motorized bike and after I installed this it gave me a pretty significant boost. I do have to say, the screws it came with did not work and were too small. If you have a chinese 80cc/100cc look for a metric 6mm all thread and the nut for it. Get 2 pairs and you may also want lock tight. The material used was rusty old scrap so before installing you may want to get a wire brush and scrub the flange. Solid 5/5. The value is great and sounds really good too.

Love the sound, the look, would recommend getting one if you like a louder sound and faster speed with more of a powerful kick when you slowly accelerate. Love it, good for the money in my personal experience. Can get kinda hot on the leg though. But that be fixed.

It fits the Anbull 2 stroke motor PERFECTLY

I was going to use it on my everyday Rider. Except my saddlebags got in the way of the exhaust. So I'm using it on my 80cc racing bike. Which I haven't started work on yet I'm just collecting all the parts I'll have to clean up the exhaust port on the muffler to get a better flow. The welding is not that good on the inside of the exhaust. It is very good looking and I'm pretty sure it will fit just fine on my racing bike.
