EVO M series has been a Big Gun staple for over a decade. Though there have been changes and improvements over the years, the goal has always been to produce noticeable performance gains. The deep and throaty tone of this KFX 90 EVO M exhaust system is sure to make even a grown man feel like a kid again. EVO M series is perfect for kids (or adults) looking to get more power and sound out of their mini MX or ATV model.
