ive owned my 2009 Versys for around a year now, and im looking to get an aftermarket exhaust for it. no problem with the stock one, i just wanted a deeper, meaner sound to come from it...yet i dont want to have a insanely loud or obnoxious sound to come from it, because i usually go for long rides. any suggestions?? anything helps...ive looked at plenty of brands; two brothers, vance and hines, yoshimura, scorpio....any help is greatly appreciated! thanks!!
