For performance, there is none better than RPW 2 into 1. Thor, Big Slash, Deal, or Big Deal. They have good quality, great sound and even better performance ! Bassani 2 into 1s have just as good performance but are known to drag HARD in turns. I think they may have changed the design to try and prevent that, but I still wouldn't want to spend almost 800 dollars and find out they still drag ! But I KNOW RPWs are the best 2 into 1s on the market for our bikes !
