in the ads for the WB E2 they say u can change from race to quiet in 5mins w/1 screw and big gun also has a vortex quiet insert that comes w/ their race series pipe.... but wen u change frome race to quiet (vise-versa) does it require jetting change too? also if any1 runs these pipes which do u think is better for a 400ex
