Just picked up my new blue yfz 450 tonight and im excited as hell. I used to have very fast LT250r and im real pumped to be back in the game. Everyone has probably heard this question a thousand times but bear with me. I need to know which exhaust system to buy. I will be almost 100 percent woods and trail riding. Also i dont want to pay 800 bucks for a full system. what is the best exhaust for my new rocket?? thanks.
