Hey, I have been seriously thinking about changing the exhaust on my 2000 500r. I want a single can so I was thinking of getting a Vance and Hines ssr. first, does it sound good. not too loud but has a nice low noise. second, can I keep the center stand with that model. third, do I really have to replace the air filter and finally do I have to re jet and which stage?. I don't really want to play with the carbs. Thanks. anyone have the V&H have any comments positive or negative? Thanks.
