Currently (and most often) using stock SM pipes w/ 2 baffles removed. I occasionally use short Off-Roads and for very short periods use my original set of stock SMs, complete w/ all baffles. Like previous posts on this topic, I prefer the looks of the SM silencers but the constant ticking and wheezing can be as irritating as too loud pipes. My dream is to fit drag pipes but I don't want get too heavily into the jets and back pressure experimentation - maybe a winter project some year...
