I was super excited to get my new exhaust for my 2008 GS then I started riding it more. All was well and LOUD then she seemed to stop liking the new air flow. Dealer said I may need to look into getting a juice box or power comander. She seems to be running lean but it might also be trying to get use to the new mod. I don't know, that's why I'm here! Does anyone else have the voodoo exhuast?
