Finally had a chance to install my new PPE catted DP,and all I can say is WOW,car feels smoother and a little louder and it feels like it just wants to moooooove,prior to insall I had the SW catted DP,the car felt like it had a cold,rough idle,stumbling,poor mpg,could of been due to the poor quality of the cats or being clogged,also noticed the 02 sensors were pretty black????.The idle now is a lot better,will keep you updated and will try to pst a video with the PPE DP AND CORSAS,give mike B and Paul credit where its due, GO ECOBOOST POWER PARTS>and support the forum
