My thoughts exactly.Did you just start using the flexible exhaust on this engine? The picture shows stock exhaust on both, but I can tell you that the flexible exhaust is junk, it's too small even for stock ports to breath properly it ends up getting hot and losing more power as you ride on it! If you were to gut the stock exhaust it will be faster than his with no cost to you but your time and effort.
