I was checking the Corksport website and there's a $200 diff between these two.
No Catalyst
With High Flow Catalyst
I assume it has something to do with this?

Installation of the exhaust requires the removal of the stock second un-monitored catalyst. Removal of a catalyst on a street vehicle is illegal thus this system is not sold for street use. If you select the catalyst option the exhaust will come with a high flow metallic substrate catalyst which will be compliant with most states emissions.

I was looking at this too:
It says "Bolt-in exhaust kit requires no cutting or welding"
So I'm not sure what's the difference between these options...
