You actually removed the cats? What about the four O2 sensors? This car will never pass emissions.

The primary cats are the only ones that have 02 sensors. There are some tuners that can tune it so the CEL will not come on..

BETTER get a test pipe to past inspections!

idk if you saw the ad for OE, they are offering dyno tunes on a road trip. Thats gonna be your best bet. The guy who tuned my boys GT500 welded and bunged both headers to install sensors (kinda like O2 sniffers) in order to dyno tune it correctly. The money u spend for a custom tune to your setup is gonna be same or less than trying to get the CEL off and get things going correctly. thats the only way to get the most out of your mods.....
