Pro Moto Billet Fastway Spark Arrestor installation on my 2017 CRF450rx. This is a relatively easy installation process, a bit time consuming but a fun project. Let me know if you have any questions.
Jon Blenker yeah, there really isn’t a huge difference between these end caps and the stock end caps. It mellows out the harshness a little bit. I saw another guy put the additional silencer turn down caps on but didn’t hear how it sounded.
