Lastly, JDP installed some kooks 1 7/8" Long tube headers with high flow cats and then did a dyno tune, and holy sh!t it made a huge difference. The car sounds 10 times better, is at lease twice as loud at WOT, and engine response, torque, and horsepower are ridiculously better than before. Definelty my favorite mod so far.
