MUFFLER EXHAUST PIPE 

Suits  HONDA XR50 CRF50  dirt bikes and most their Chinese version copies such as Thumpstar Atomik Pitpro in 50cc 70cc 90cc 110cc125cc

This is a complete piece exhaust system from the head pipe to the tail section.

This will make your bike breath with any engine modifications, and also sounds great with a stock bike. As soon as you bolt this exhaust pipe on you will notice an increase of power through all of your Motors RPM range.
