Good question...are the pipes really illegal here in Canada/USA? I know the disclaimer under the pipes states that they aren't legal but is that for every country or just England (get my point)? If they were illegal why do so many bike shops switch the pipes when they sell the bike, remap/rejet the engine, then plate the bike for on road use????? I think the onus is on the law enforcement agency in your jurisdiction to determine if the bike is too loud using a decimeter of some sort unless someone makes a general complaint.
