If you plan on having your bike Dyno tunned in the future then I would install them. As for the popping my bike still pops with the block off plates on. The only dis-advantage I would say is you and if you have a passenger will smell like exhaust alot more with the smog pump blocked off. Also when you do your spark plugs it makes it a breeze. It is not a easy job it takes alot of patience and creative use of tools.
