I just installed one and I'm a little disappointed. The low end power is GONE and the bike needs to be maybe 1/3 throttle before it "comes on the pipe". Then it runs good, but until then it feels "choked". This may just be a jetting issue, but I thought I'd query the People In The Know before I go buying jets. On the upside, the pipe is nice and quiet. Very pleasant. Opinions, experience, advice?
