fatboyz i have never seen a stock exhaust flow that well with a tune... i must have a shitty tuner.... i'd love to see dyno sheets if you have any?

i feel that the stock exhaust was VERY restrictive.... and the stock cat!... that must go IMO.... run a berk 70mm or if track use just a TP.... thats where you gain some good power... and then if u tune also, you will be surprised...
