The pipe fits many Chinese models with a 125cc or 150cc GY6 4-stroke engine, but you need to double-check your model to avoid surprises, especially with the 150cc versions that it doesn’t fit.

The welds on the exhaust tip might seem rough at first, but I was reassured by how sturdy they are. I did have to be careful with external impacts, as a collision might damage the welding joints.
