First off does the 00+ have 4-2-1 exhaust? I thought I read that it does. I thought all new bikes do? I looked at it and it looks like 4-2-1. I've had others... Professional tuners say its not. Are looks deceiving? Is it how the collector is made? I've read that 4-2-1 give smoother torque curves and better bottom end. 4-1 more peak horsepower and torque not smooth. Any exhaust experts out there?
