A catback muffler system means, from the Catalytic converter back. If you don't know what a catalytic converter is, its the round or oval thing near the front of the that comes off from the down pipe.

and remember, if you dont have the downstream o2 sensor, or emissions testing, the cat does nothing but hurt your car. it is evil:nervous:
