For christmas my wife put down a deposit on the best bike I have ever ridden. I picked it up on May 15 for $9500 no tax, freight, or set-up charges. So far all I have added is a lockhart phillips tank cover (about $40). I want to add more hp and noise now but my budget is small. I think I will try the drilling in the stock pipes as stated in one of the other postings until someone comes out with a 4 into 2 into 1 system that works. Has anyone tried removing the baffles/packing in the stock pipes if so what was the result and how did you do it? I would like to get the web address for Akrapovic. I am intrested in a deep throaty noise with maximum hp increase. I am also interested in a fender eliminator kit but competition werkes says they won't have one until late this summer. Just wanted to put my name out there as I am new to this site. This is a great site by the way!!
