What is the Tru-Flo stamping process?

The Tru-Flo stamping process is how FMF Racing forms the metal for their pipes. It's designed to ensure that each pipe has a perfect fit on the intended motorcycle model, making installation more straightforward.

What kind of performance gains can I expect?

This Fatty pipe broadens your engine's powerband, which means you'll have more usable power throughout the RPM range. You should notice improved throttle response and a noticeable increase in the over-rev capability of your CR250R.

Does this pipe come with everything I need for installation?

The pipe includes the necessary O-rings to help ensure a proper seal during installation. It's designed to be a direct replacement for your stock pipe.
