forgive the newbie question...I have been a sn95 and fox body 5.0 guy for awhile, then I was outta the game for a few years, and last week the wifey finally let me get back in. I bought an '02 GT. I was wodering, what all has to be done to make an o/r x pipe work properly on these cars (no check engine light, no screwy a/f ratio whatever, seriously, complete newb to the mod motor! lol, so I need all the info).
