yosh rs3

just got my yosh rs3 exhaust installed yesterday, there are two screws at the end of the can.....what are these mysterious things...do they hold a silencer in or what are they????

i think there should be one alen key at the end of the pipe that removes the silencer.

Yea that removes the silencer

thanks guys.....its about 15 degrees right now here in kc or i would go out to my garage and do it......but itll prolly have to wait til next week......thanks again though
