just thought i'd throw in my i cant comment on power/driveability changes but i bought my '98 superhawk last may with them(D & D's) installed, look and sound a hell of alot better than stock. at low revs it could be mistaken for a chopper, and when wrung out absolutely barks.
I bought my bike with the Jardine high mount slip ons and they sound great, neighbor thought it was cool compared to his nighthawk one hasn't been packed and I really like em. never have heard seen the stock pipes but with the Jardines you keep the passenger pegs only Devil makes another pipe that let you keep em. That I've been able to find. Targa sells em for close to a thou. Supposed to get 3 to 5 more horsepower with em too.
