I cant remember the guys name up at Brandts in Wabash, but he is a decent tuner. or drive down to Kokomo and see Mark Harrell(last I knew he was teaching up in ft wayne and may bring the dyno to you). thunderheader, v&h pro pipe, supertrap 2-1, or d&d fat cat are all good pipes. I am really liking the black v&h pro pipes. I like 2-1 for the broad torque curve you get with no dips.I am new to this site and thought i would say hello. Just bought a new 2012 street glide 103. Looking to put a new aftermarket exhaust on and thought i would come here and see what people think and get some good advice.
