Thanks. I found some pics of the engine on them and saw the difference between the red and blue head motors but didn't know if that translated to different exhaust.
I am looking for a set of triple pipes, reverse chaincase, longer track setup (I have the 141), better than stock shocks, upgraded reeds, and the magic wand to turn it into a new turbo 174 sled. So far the wand is the hardest to find.
