Honestly, because the middle man has the best price ive found for a set of high mount slip ons. $550. Leo Vinci pipes are the same price as well. Eveything ive seen from Sil is $100 more or so.or you can save some $$ and just buy the sil motors cans from motowheels.com or spareshack.com. FBF doesn't make their own cans. they buy sil motors and resell them with their stickers in the box. this being the case, why deal with an extra middleman?
