First time silencer re-pack: I have an FMF re-pack kit (it's just the packing), and it says to remove (3) 8mm bolts to slide the outer body off the inner. Looking at my silencer, I can see the (3) bolts in the front that are removeable, but there are (2) rivets farther up the body toward the exhaust exit that I am HOPING don't need to be drilled out, and another 8mm bolt farther back than that (not shown, it's on the wheel-side). Leaving those rivets and the single (not shown) 8mm bolt in place, should my silencer come apart by just removing those (3) bolts at the front?
