Can anyone else check to see if they have this? I'll try to get a pic a little later.


There is a weep hole in the resonator (front muffler) and in the (rear) muffler to alow water to drain out due to condensation buildup. If holes were not there water would stay in them and promote rust buildup. The soot look is just carbin mixed in the water then dried to the outside case.
