Get rid of the cats and sell them. The rear o2 sensors can either be tuned out, or you can get a set of o2 simulators.

Looks like you have heads/cam, so definitely ditch the cats. You will gain power.

The SES light for cat/rear O2 removal can either be turned off with custom tuning, or with O2 sims as mentioned above.

I dont' think he has done anything to the car yet. Seems its still stock with all the work coming soon...

But definitly take the cats out. You'll free up some more ponies

You're right, looks like his sig is a bit messed up with that last part being at the very bottom. I didn't even notice it.....
