Hey, I'm thinking about getting a slip on or something like that. I don't have the money for a full system, but I was wondering who's got the best all around slip on, u know, weight savings, power, i think i have to have a spark arreastor for where I ride. Alsooo...If I got something like meier plastics, please tell me they don't have those stupid recesses for the warningplates?? Annnndd, one last thing, with the carbon fiber headlight cover, do u have to take out the lights, or is it just a cover...thanks
