Thanks for your advice lito, but could I have fuel pump problem even tho the car hasn't reach 19k miles, it's almost a brand new car that hasn't been run on the track and only run twice over 100 mph it's not a daily driven car, like I noted before the only thing I hear different after installing the headers and xpipe was a noise from under a car that sounded like air escaping but I don't from where that's coming from, and also i think it might be the o2 sensors and I would like to find a way to see if they are working properly
