Now i have heard from a muffler shop that you can get a chip for pickups to bypass the o2 sensors so you can cut out your cat coverters, i know not supose to but im from a hick town in northern canada and well now one cares and theres probably more without than with im just curious as to if anyone has heard of this chip or have installed one. thanks

 

Try the exhaust forum about 3/4 the way down the page.

 

I believe they are called MIL Eliminators or something to that extent.

thank you i will search for that product. and i believe (well at least my 99) have 02 sensors before and after, but the older ones did not
