Hello everyone, I own a 2013 YFZ450 carb model (black&silver if that helps). I've been looking online for a complete exhaust system to buy which has proven to be quite frustrating as I'm sure others have come to experience with online products they wish to buy. Most of what I come across are systems for 04-12 models, and an abundant amount which are for the R & X models. So can anyone reading this please help me out with a comprehensive low down on which years are will crossover and be able to be fit my year? I would be most appreciative with your help. Thank you for your time and effort with my request.
