hey guys, i recently bought a banshee, as you all know and it came with cpi pipes and cascade silencers on it. My bike is just ported, but these pipes really kick in hard. I get amazing power from them. I cant even compare them with my rockets on the stock bike. The pipe will just keep pulling until you are desired. I now switched them with my rocket pipes, to see how the rockets perform on my setup. Ill do a review for those too
