to be perfectly honest jon, i have no idea what that consists of dude. ive read about it a few times but cant seem to wrap my head around it
EDIT:
Cat-back (also
cat back and
catback, and more recently
axle back) refers to the portion of the exhaust system from the outlet of the
catalytic converter to the final vent to open air. This generally includes the pipe from the converter to the muffler, the muffler itself, and the final length of pipe to open air.
never mind i got it, i love google. if that info there is right, then thats whats being done to my car as we speak ^_^
