The XDP Bellowed Up-Pipe Kit XD178 for your 1999.5-2003 Ford 7.3L Powerstroke is the fix for a common issue that robs power from your engine. Due to expansion and contraction, and extreme heat cycles, the factory installed "donut" gaskets designed to seal your factory up-pipes will begin to leak over time. When this happens, engine performance can be reduced drastically. 

The XDP Bellowed Up-Pipes eliminate the troublesome "donut" gaskets and replace them with a durable steel crush gasket that will not blow out or leak over time. The Up-Pipes feature a bellowed design that allows for expansion and contraction without needing to rely on a finicky gasket.

  • Bolt-On Replacement
  • Eliminates Factory "Donut" Gaskets
  • Bellowed Design - Allows For Expansion & Contraction

Maybe a little too well made?
I bought these up pipes 1 year ago, they seemed well made and 1 year later the pipes still look brand new. Now my only complaint was that I had an exhaust leak for the last year I just didn't feel like dealing with, untill yesterday when it got bad, turns out it's where the up pipe manifold meets the turbo had popped out the v band clamp, after hours trying to get a clamp back on I realized the v band flange on the manifold that came with with up pipes was thicker then the stock manifold, five different v bands none fit over that manifold properly when mated with turbo, found my oldanifold and sure enough the one that came with these up pipes is a good bit thicker (takes up most of the v band by its self) wish I cought that a year ago, would save my self a whole lot of trouble and used stock manifold with these up pipes, or sent it back and got a replacement. All in all though the pipes were great quality and will buy again (I'll just triple check fitment first,smh )

E350 7.3 Powerstroke Up Pipe
After realising that like all the other powerstrokes out there, the down pipes were leaking. On this last refresh. I installed these. Great quality, good fitment. I chose to wrap them in the DEI titanium wrap. If these are like any other XDP products they should hold up for a long while. Installed on an E350 so pulling off the dog house gives your great access to the turbo and up pipes. Order Number: 2198756

Good so far
Install went great, I had the tranny pulled out so it went pretty easy. Haven’t had a chance to test it out yet but the product appears to be of good quality. I thought the cast iron collector was a little funky, mine looked like someone took a grinder to it on a couple parts but it all went together

Questions and Answers

I have a 12/6/98 ford F350 superdutyturbo 7.3 will your kit work?
View Staff Answer 

Vehicles built before 12/7/98 are considered early 99 and vehicle built after 12/7/98 are considered late 99. (You can also contact Ford with your VIN to verify the up-pipes on your truck vs that which is found on the latter 99.5 trucks to be 100%.)

Will this fit a 2001 7.3l excursion or just the super duty?
