I got the TOR's as part of the bike deal. I just passed 500 miles on the bike and just (2 days ago) took it in the 500 mile service and they put the TOR's on. So my stock part is still at the dealer and I have 10 days to pick up my stock parts....So I will have a stock system if I ever need it....
I agree with drilling of the stock pipe. This was what I did finally on my Harley in Huntington Beach CA....there they went with "the bike has to have stock pipes", and they would pull you over, noise or not, if the cop thought your pipe was not stock and the cops got real good at spotting non-stock pipes.
