  • Very good performance upgrade
Size: black exhaust
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. ... show more

  • It is what's advertised
Size: black exhaust with muffler
Works good for how I'm using it. Definitely picked up some tork with it. I had to modify for my application but works good. Sounds good kinda thinking about ordering small welder to potentially open it up and see what I can modify on internal but for now working good. Might want to boar out a bit because the solid metal to braided metal is like .25" thick so there's that. I like it ... show more

  • Looks and sounds great.
Size: black exhaust
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.

  • Waist of money
Size: black exhaust with muffler
The Exhaust worked fine but no extra power. And the tensioner didn't work at all.

  • An upgrade must.....
Size: black exhaust with muffler
Makes a difference in noice. Hard to work with at first - * I suggest clamping down your exhaust first and working your way down, before connecting to engine. (Use red locktight - for 2 screws for engine) - My installation is supper sturdy!!! Note - Make sure your pedals don't get in the way before installation- Take your time. ... show more

  • Easy instalation!
Size: black exhaust with muffler
Sounds much better than the kit exaust and provides better back pressure and more power. I will suggest this to anyone sence its also a better fit than the junk that comes with the kits. After 2 weeks of use the mounting bracket tore loose and now i hve a hole in the exaust this is my fault though sence i didnt mount the thing properly annd secure. Ill weld it back togeather and i still love this exaust just thin metal ... show more

  • Nice
Size: silver exhaust with muffler
It's exactly what I expected. Sounds great. Not too loud like everyone describes. Looks great. All parts arrived tho I haven't used the spring tensioner as the stock still works fine. This is my 1st build. Bought an HP carb as well but wwn5ed to break in the the motor 1st with the NHT carb. Maybe a drain for fluid collected in the silencer or I could just change the angle I guess. 🤔 ... show more
