@ogshady12 most common issues would be a sudden decrease in fuel mileage. Most commonly you will experience an overall poor vehicle performance; rough idling, stalling, hesitation on acceleration, etc. So I would suggest you redesign and find a way to connect the sensors.

@ogshady12 drill a hole in the pipe behind the cat 4 to 5 inches and have a bung welded on . The truck will not pass a emision test without the o2 sensor reinstalled
