Hey guys, I just recently bought my 2003 Gt 5-Speed and it is 100% stock down to the paper filter it came with. Anyway, what I want to know is the power difference between a catted and non-catted x pipe from Magnaflow. Also, will there be a drivability issue with no cats? I've heard the MIL eliminators are not 100%. Oh, and how do you guys with no cats pass emissions?? Thanks for any help.
