    Default 94 catalytic converter question.

    i have a 94 7z1 silverado clogged cat. is what ive narrowed it down too. i have a flowtech high flow cat off my old truck. and im wondering if i could maybe make a spot for the o2 sensor to go into. i just want to keep the truck as stock as possible and if i buy the right adapters i think it may work.
