I have my 02 GT and it has some sort of MAC cat-back on it from what i can tell. I have not had the car up on a rack yet to see what it is for sure.
1st... Is MAC a pretty good system?
2nd... Besides shape, whats the diff between a H pipe and a X pipe?
3rd... I know it has a K&N air filter *its in a black plastic "box"*. Is this stock and if so why change it? K&N is supposed to be the best right?
4th... I am very very new to the whole V8 Domestic scene. I have had nothing but a 91 laser 2.0 DOHC for the past who knows how many years. I know enough about the Gen 2 Eclipes, but thats not what I ended up with he he he

I am looking to add on to the car slowly and if a few of you were to sort of Map the Course for the new guy... I would be thankful.
