Which exhaust system is better? for street & track. Also, which one sounds better?

 

Neither one will knock your socks off in horsepower gains. You will definitely need to get your carbs rejetted as well or you are going to have some serious flat spots. I have always been partial to the V&H sound myself, but of course that is purely subjective. My favorite for the RR is the old Two Brothers full pipe.
