Dorman Bellowed Up-Pipes 99.5-03 7.3L Ford Powerstroke

Bellowed Up-Pipes are what you need to cure those leaking stock up-pipes. It isn't a matter of if, but WHEN your factory up-pipes will start to leak, and when they do, this is your permanent answer. Because they used a bellow, rather than a donut gasket, these kits will not leak and will ensure you are utilizing all of the boost to spool the turbo. When your factory up-pipes leak, you will begin to see a loss of power, mileage, and increased EGT's. This kit comes complete with everything you need to swap the leaking factory up-pipes for the new bellowed style, including hardware, nuts, and bolts.
