will be a great difference but you prolly dont need a 12 tooth..thats gunna be crazy bottom end with those mods..1st and maybe 2nd will be useless..u could prolly pull a 14..you'll have to rejet to
It will feel like your going faster at least.... but in reality you will most likely be slower... you wont have enough gear to actually use the power you gained from the pipe... id reccomend stock gearing untill you get into the motor a little bit.
