can someone explain to me more about this head mod? I bet yamaholic knows lol. I am seriously thinking about putting pipes in my viper because the average of you guys are getting 9-11 mpg and on my stock viper i get 11-12. I already have the rear heat exchanger. If i was going to put pipes on it, what else would I need? I have a 136" ripsaw and am most likely going to put 108 studs in it.
