I bought an 03 mach 1 about a month ago and took it to the track for the first time the other night. the car is stock except for a bbk offroad x pipe and flowmaster american thunder cat back. My best time was a 13.29 @105.73 and it ran consistant 13.4s. the temperature was 65 with a humidity of 100%. How does this sound compared to most stock ones? The reason I ask is I put the cat back on 2 weeks ago and it didnt feel as thought it made a difference. I put the x pipe on just before going to the track and the car actually felt slower. Anyone else experience this. Basically wondering if it is slower or if its just me. I am thinking of going with a catted x to regain some back pressure. Will this improve my times? I am going to put in 4.10s before going back to the track and am looking to be in the 12s.
good 1/4 time?

well if you just put it on before you went, there is a good chance that the computer hasn't adjusted to it yet. i think that there is more in it though. imo.
