[full tilt viper]

If anyone outhere is running bender pipes with H Hitters I would like to know a set up that works well. 02 viper,speedwerx head, 8 tooth drivers.144 studs,1.95 ratio,roller rooster sec,41\37 & 47\43. Simmons supplied primary and sec spring.I do mostly trail riding and want good corner to corner speed.
Last year i ran hammer times ( blew apart) They had good low end power but very little top end. Any info would be great!
