First post on this site and hopefully not the last. I purchased a 2000 SP1 last November, completely stock, with 8000 miles on it. New to the V Twin world. I've had 4 cyl sport bikes, 3 cyl street fighters, but nothing beats the growl of the V Twin. Set for life. Any recommendations on after market pipes? Not much left out there for an SP1 so any recommendations will be gladly accepted. Stay safe.
