[salt_water_guy]

I got a 05 chevy truck 1500 4.8L I want to do away with the catalytic converter's if i can how do i bypass the O2's Thanks for the Help..

there is no reason to do away with them, there is no gain what so ever unless they are bad or clogged.
YOu can have the rears tuned out.

i suppose in theory you could "bang out" your cats and put in some ebay 02 fakers? But if Alabama sticks a sniffer in your tail pipe during inspection you wont pass emissions.

call BlackBear or Nelson and get your self a custom tune and ask them to tune out the rear o2 sensors. Or buy thunderbolt highflow cats and get the ones with the o2 bung on the back of the cat.

Get a custom tune to delete the rear O2's, forget the simulators off ebay, they are junk, plus with a tune, you get the benefits of a tune.

As mentioned, there is nothing to be gained by this unless the cats are plugged.
