u recive back pressure from the expansion chamber i do belive, so having no muffler just makes it luder. Now yes a bike can start without a pipe, once upon a time my motor got flooded an di was taking it apart i took off the pipe and i pulled the cord to get the gas out and it fired! loud of heck tho my ears were ringing.
