Model 2002. Original not the quiet version. Was under the impression they were going to be a little quieter than V&H. Not quieter but much deeper and more aggressive sound. Takes a little getting used to when let off throttle, it growls between shifts which my daughters seem to like. I had S&S upgrade to bigger cams when the cam belt broke last month. Slowed the engine sounds down to where they should have been in the first place. Haven't noticed much increase in power from the cams and pipes but I do like the sound. Have to wait til the newness wears off the the rear tire before I push it. This is third rear tire in 12,000 miles. Avon has dc'd the rear 220 R20 that fits the Wolf and current stock tires are already 4+years old already. May have to find another tire make next tire change. Got 5600 miles out of first, and around 6000 out of second tire. Scott
