Awsome pipe, looks really good. Made awesome power for bottom and mid range. For top end u atleast have a little bit more or stock. Great sound only disappointed in that u can’t use ur heat shield with this pipe.

Excellent product for XR250R

Very nice pipe that saves weight and increases low and mid-range power, when the bike is uncorked and jetted. The fit was perfect with no issues. Also sounds great!

A: It is recommended to do so since this will change the fuel/air ratio a bit since your engine will be breathing more.
