Thanks for the advice. I have had Yosh and Muzzy on other bikes and I am leaning towards the Muzzy also (in my opinion better quality), however I read an article in Sportbike magazine and they said the Yosh full system is awesome for the 2000 R1. My main concerns are weight loss, increased ground clearance and of course performance.
I'd say Muzzy. The titanium system weighs less than 7 pounds(!) total. That's headers, pipes and muffler together. A sportrider test of full systems showed the muzzy to be the second most powerful (behind 1st place by less than 1 HP), the lightest by a wide margin and among the LOUDEST pipes.
