Hey guys. I am quite new to the scene. I have owned my '03 for a few months now and have only put about 100 miles on it (if that). I have no complaints with performance whatsoever (still haven't come close to 'pushing it'). But..I do wish it had a more aggressive sound to it. I am not too eager to spend $300+ at this point in time on a slip-on so I was wondering if any one on here has modified their stock exhaust at all. A buddy of mine altered his gsx-r exhaust by shortening it and this made a dramatic difference. Would someone provide me with some advice on this matter and possibly direct me to any related thread or 'how-to' on this? Thanks in advance!
