the exhaust says cat-back witch I thought ment no cats included but in the picture it shows cats so do cats come with the system or no?

 

cat-back means "from the end of the cats to the tips" just like how turbo-back means from the end of the turbo to the tips. all true dual exhaust for the G will be from the cat-back because they replace the OEM y-pipe design. OEM style single pipe exhaust systems will be from the y-pipe-back which is why some people get newer higher flowing y-pipes as well.

The borla does not come with cats, what you are seeing are resonators for sound tuning of the borla system.
