    Default Off Road Exhaust help - ford part number research

    So I am in the process of getting out lots of parts I have bought over the years to get the 4eye back on the road. Many years ago I bought this off road exhaust on ebay from a guy who said he bought it from Bondurant racing when they sold some NOS parts they had lying around. He said they had bullet mufflers welded in and you can see in the photos something not normally there is there.

    I have emailed the pictures to Bondurant but no one took the time to respond or even acknowledge that I sent them an email. I have done the usual Google search but you will see from the photos that these do not look like high flow cats but do look like some type of muffler system.

    Take a look and see if anyone has any info or comments to add. I am putting them on the car but did want to know a little more about them. There are no less than 6 different part numbers or codes on them.

    Thanks for helping out.

    UPDATE: I have emailed Roush Industries as they built the Mustangs for Bondurant. Maybe they can help.

    Bondurant went bankrupt a couple of years ago. I think they reopend recently, but not the same people. The service part numbers are 1994 Mustang.
    Bleed Ford Blue! '84 Grabber Orange SVO, '88 Saleen 1 of 4 w/Automatic, '89 Steeda, '71 DeTomaso Pantera GT5 Wide Body EFI 4.6 DOHC and some Old Ford Muscle w/ BB power. 1.21 Jigawatts!!?? PETRO EXPRESS=CITGO=BOYCOTT!

    Yeah, just by the part number alone, these could not have been made for a "true" Fox. Even though the '94 IS sorta, kinda a Fox still but also not really.

    UPDATE

    After sending an email to Roush Racing months ago, out of the blue I finally got a response. I had found out that Roush modified the Mustangs that Bondurant Racing used in the late 80's and early 90's. I sent the email with photos and asked if anyone had any info.

    Here is the response I received:

    These were custom fabricated by Roush during our involvement with the Bondurant program, using the Mustang Ford service part as a starting point. These parts are one-offs and no replacement parts exist.

    So that was at least good news as I did buy what I was told they were. They area also bullet mufflers welded in as you can put a light in one end and see all the way through. May have to modify the brackets to make it work but all my research shows there is a way!

    Here is a better photo.
