Looks great and it sounds amazing! Very aggressive! I installed it very fast and easy in my 2003 Mitsubishi Eclipse GTS! You don't really notice it until you get on it and are above about 4,500 rpms, but it sounds like a beast! A must have! I haven't tested if I get better gas mileage or anything and the power increase isn't very noticeable, but it looks good and sounds good. I wish AEM had a chart to show the power increase. I'm curious with how much more horsepower I have now. Thanks AEM for making a great product anyway. I can't complain.
