What does it mean when you say catback exhaust such as flowmaster catback exhaust. Does this mean the cats are still there or completely removed. I know this is a no brainer question, just want some clarification. Thanks......

 

Cat back refers to the portion behind the cats... in our case, the very end of the exhaust. The mufflers are in the catback section.

Engine > Headers > Mid-pipe (H or X for the V8's... an off-road mid-pipe has no catalytic converters) > Cat-back (muffler portion) > open air

I think that solves it.

 

^^^ yup

 

it includes everything behind the h-pipe. (mid pipes, muffs, tails) the h-pipe is the part that has the cats.

even a non-cat system is called catback.

3 parts to the whole thing, 1. headers, 2. h-pipe (or x or whatever you choose) 3. catback
