Welcome to FTE and the Big Bronco Forum, we will endeavor to get you the most accurate info we can.

Put it back! It needs to go into the crossover pipe. Then the exhaust can split again and run dual. Not running it this way will give you odd O2 sensor readings that will most likely generate fault codes and alter fuel-air ratios caused by the inaccurate readings. The inaccuracies will cause a "lean" condition that will lead to poor performance and premature spark plug failure.

why are you running duals? mandrel bent Y pipe or bassani y pipe with hi flow cat and run single exhaust. it will be cheaper and perform better.

Hey Elmer,

I had an 89 Bronco that Headman full length hedders and flowmasters.It was loud and sounded great.Like the others said just plug the senser back in.

I ran my pipes out behind the rear tire and in front of the bumper one each side of the truck.That was a nice setup. The Mustang sets off car alarms.LOL

Thanks for the Help

I will keep the O2 sensor and just run a single glass pack after the y pipe.
