I have a 2000 xr 600 with 25 miles on it that I just purchased. Does anyone have any prooven results with aftermarket exhausts. I just want to unplug this beauty and get some more power without going over 100 db. I will probably put on a new air filter, some kind of pumper carb (edelbrock?). How do you remove the restrictor in the air filter and how do you remove the stock baffle. Does this bike need to be uncorked like the 650r and does it respond well to these above mentioned parts. Please help. It seems everyone has an opinion on which is better but does anyone have any prooven results. It also seems when people make their bike louder that is has more power and I know that this is not always true.
