Does this x pipe come with o2 sensors holes

  • For 1979-1993 Fox Bodies, they only have one O2 down flow. The BBK Catted X-Pipe (79-93 5.0L w/ Long Tube Headers) has it's down-flow located in between both of the catalytic converters.

    Pleasantly Pleased

    I have a 331 w/ 185 AFR heads, Kenne Bell SC, bbk long tube headers and a flowmaster 50 series delta flow cat back. Previously, I used the bbk off road x pipe for three years and enjoyed it very much, however the car was very loud, raspy, and droning. I purchased and installed the bbk high flow cat x pipe about a week ago. Extremely happy!! Aside from finally getting the AWESOME, yet not offensive, tone I have been searching for, the cats have clearly improved the drivability and overall manners of the car. I couldn't be happier! My wide band o2 sensor is even reading more steadily and reliably, making tuning easier. I would like to also add that after speaking with BBK, I learned that BBK's cats use the metallic media as opposed to the ceramic and can be used without an air injection pump if desired. Best of luck with your project!
