hmm im thinking of resorting to just unplugging the CEL if its gonna stay like that. i dunno how to jump the ecu, not much of a computer guy. but also another thing i noticed when installing the cat is that i had to make an extension for the rear O2 sensor. both O2 sensor mounts on the new cat are at the front of the cat. not one in the front and one at the rear like the stock cat. but the original rear O2 sensor is mounted at the bottom of the cat, pointed straight at the road! like 2" ground clearance... would it be bad to just take off the damn rear O2 sensor? after all the cat DID come with one O2 mount plug. thnxx

-oh yeah and i dont have to worry about emissions..so that wont be a prob for me
