I need help. I currently own a 03 SXViper and I love it. My buddy has a 05 Renegade 800. When we race it all depends on who hooks up. I'll win one then he'll win one. I want to do some mods to my sled to smoke him everytime. Everyone says that pipes are the best way to go but I have also heard that vipers aren't very reliable with pipes(unless they're are tuned right) . Also I don't have a large budget. Help, please!
