recreational/aggressive rider   I just recently installed this product on my kfx 400 2003. In conjunction with this product I added the power up kit and am running with my air box lid off.First off the fit and finnish are very high quality and the instalation time of all the products I purchased was around 1.5 hours.My quad now has a very throaty sound and throttle response is crisper throughout the entire rpm range.MY machine seems to wind out quicker than before but the machine is definitely louder than stock.   Reviewed by:  Paul Renaud from Windsor Ont canada. on 2/5/2007
