same page buddy , bike hits around 90 mph give or take 5mph and i have minimal work doen ........ 30 over , mx port , 2 : 1 , timing , pipes , whatever bullshit i forgot ..
i personall think two into 1 is better and easier for your skill ./ type of machine setup. and you will not loose alot of top end . infact not much at all ... what im trying to say is its not going to make your bike slower
