Don't know where to start rambling so I will start by saying why change the exhaust? The bike has plenty of power as it is. Heard all the stories pros and cons of stock, slip ons or full system. Let me tell you if you try to justify any reason for keeping the stock or going slip ons don't bother. I wanted quiet, thought the power was enough, wasn't bothered by the heat or weight didn't want to spend the money. Then there was slip ons removes the cat in the exhaust loses weight frees up the back pressure. Then theres the full system loses most weight gains most top end hp. So which one is best? Compared all horse power dyno charts for all three and it seemed that slip ons gain a little all the way through the rev range and are easy to install could be more of an impulse choice. With a full system it seemed you would loose bottom end power and gain mid and top end.
Well I had to ask myself which one I really wanted a full system won over for a couple of reasons. Chose the Yosh for their dyno results of smoothest power curve good quality and quiet exhaust note. I thought it would be loud still and lose all my bottom end 3200 and lower. Well I got done today and holy sh*t everything was better than I had hoped. Throttle smooth and crisp right from the bottom no loss in torque (have the quiet baffle in). Power everywhere what was I thinking not doing this sooner. It seems to me that this bike was designed for this pipe and Kaw was forced to install the other for emissions - obviously. I like everything about it 90 degrees out and it has more power everywhere than when cooler out! The handling is smoother and crisper. Chain maintenance is so much better. So If your thinking about slip ons skip it or stock chuck it there doesn't seem to be any down side to the full system. I don't even have a map loaded for it yet. Love this bike more than ever.
