1st:Is an extra catalyst needed if making it dual?
2nd:X or H
3rd:what does catback mean?
4th:best brand?
5th:will i have to change headers?
6th:will i need to add an O2 sensor?

I had a off road bassani x pipe with glasspacks mufflers on my 2000 and it sounded good but would have sounded way better with a two chamber muffler. On my 04 I just did a cheap system, I had them cut right after the cats and run pipes to a set of Thrush Weld mufflers with dumped right after the mufflers and it sounds pretty good. Definatly am going to go with off road h and either thrush weld or flow 40s for my next exhaust system
