Our EVO M series has been a Big Gun staple for over a decade. Though there have been slight changes and improvements over the years the goal has always been to produce noticeable performance gains. We can’t forget to mention the nice, deep tone that comes out of the EVO M series mufflers which is sure to make even a grown man feel like a kid again. The EVO M series is perfect for kids (or adults) looking to get more power and sound out of their mini MX or ATV model.
