I like this mod, personally because I own Yamaha Lagenda 115ZR. The exhaust are doubled and as you can see this one is on the left side (stock Lagenda 115Z only got 1 exhaust at the right side). The owner, Halim Bmc (forgot to ask for his name, anyone please help me if you know the owner, thanks Mohd Arif for the info about the owner’s name) tells me that the exhaust mod help to achieve higher top speed.
