Dunstall Replicas just installed on my 05 Speedie after return from crankcase replacement. I needed to reduce from 1 3/4" headers to 1 1/2" pipes so had 2 12" pieces of 1 1/2" pipe cut, then expanded one end to 1 3/4" at a local muffler shop, that way I could mount the shorter pipes in the same place under the passenger peg mount. I may paint the reducers black or weld a chrome cover over them but they are fairly ok just left unfinished. The sound is louder than stock but very livable and allows me to hear the throb and power of the engine as I accelerate, shift and decelerate, nice idle too. The best part is they cost a whopping $52 apiece at Dennis Kirk w/ very nice chrome + $10 for the reducers!
