call me crazy, but, i saw a video of these on a RS, so, i put some on my 1st Gen! easy, less than 100 bucks. took a little tweaking with hangers to get centerstand to come up, but done! man, they sound good in the saddle for sure! ps...no welding. thrush part #24202. ID 2", overall length 27". used reducers from advance auto, 4 clamps. custom hang strap courtesy of local harware store, painted black.
