i've had an issue bugging me for awhile i dont know much about exhaust systems so i have some questions and i've done some reasearch but it confuses me. sorry i dont know much on exhausts.
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?
sorry for so many questions but im trying to learn

1st:Is an extra catalyst needed if making it dual? No, you can run a off road mid pipe with no cats more power but in some states you wont pass emissions

2nd:X or H? H=classic muscle car sound and Low end TQ X= high pitch sound gives more of a bite and its give 1-2 more HP then the H and its top end TQ so you will feel a difference at 3,000 rpm and x pipes sound better with a round muffler like SLP, Magnapacks, Borla stingers, or pype bombs. ( I run a off road x with SLP laoudmouth cat back I love it!)

3rd:what does catback mean? Cat back means the exhaust connects from the cats back any cat back system passes emissions

4th:best brand? Top brands out the are Borla, Magnaflow, Bassani it's all what sound preferences you like

5th:will i have to change headers? No, but for better sound and power long tubes are the way to go, unless you plan on turbo, the JBA shorties are the best way to go and there the only shorties that pass emissions.

6th:will i need to add an O2 sensor? No but if you run a off road pipe I suggest you get MIL eliminators($80) or a tuner ($375) to keep the check engine light off. Also for some mid pipes o2 sensors extensions will be need for the rear 2 o2. ( I run a off road X-pipe from pypes and I needed o2 sensors extensions and I bought the MIL eliminators also)

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

i got an Off-Road X-Pipe by Pypes with dual Flowmaster 40`s and i didn`t need O2 sensors extension.. But yes i got the check engine light on... i will buy a tuner to correct this.
