EZ ADV Upgrades: Helping the Katoom Breathe Freer and Cleaner

Rottweiler includes one machined billet velocity stack with its stage 2 and up intake kits. This is necessary due to the large foam element filter, a reduction in the height of the velocity stack was necessary, but only on the rear velocity stack. By reshaping the velocity stack with a 180 degree bell-mouth opening and altering the taper of the bore Rottweiler was able to achieve smoother induction flow characteristics as well as velocity, optimizing the added flow volume of its intake systems.
