hi guys.i have a 08 busa 1440 with head ported, pcv,bmc filter,yoshimura cams and ti force full exhaust 4-2.the bike works good but i want to change the exhaust with a brock alien head 2.what about the power its gona be better or not?
The tiforce you got a dual system? The Alien head 2's I just sold should net 2 hp over normal alien head on a stock motor gen2. I would guess 5hp more on built motor...The weight lose will add a bit..
