the exhaust on these cars are VERY restrictive....you have a 40lb resonator mid-cab plus a 25lb muffler on the end..this was at night so my CAI came into play (drawing in much cooler air) and the fact that I was manually shifting the atx, which makes a huge difference. try it sometime..there is a noticeable difference in get up and go with you manually shifting...i will just have the video next time to prove it..anyway...
