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

Unfortunately I've been driving like this for a few years. I never knew nothing about up pipes. This is actually my first diesel. I've always felt like my truck of all trucks was heavy. At least it felt like it was heavier than most as far as the pulling. I drive a 2000 F350 crew cab dually. I explained the situation to my uncle when I had a bad injector. That's when I was told about the up pipes. While getting all new injectors, I came to Xtreme Diesel to order the kit XD178 that came with everything I needed to bolt it on. When I tell you it was a night and day difference... I wish I knew about these a lot sooner. Way better than the factory ones. The craftsmanship is great. The instructions that came with it was on point all the way to the tool breakdown. The bolts that are connected to the original collector were seized in there. I found it easier to take the whole turbo off to access the collector. I then took a Sawzall and cut it all from up top. The bottom ones...two came undone and the other two I had to cut with a torch. Other than that it was a perfect install. I absolutely love this setup. I will buy from you guys again. Thanks!
Great product!

Fit and quality are excellent! This was on of the few things I had not changed out, but should have done it sooner.
Poorly made collector
(Minnesota) | January 16th, 2021
The quality of the pipes seem fine, but the collector was so poorly made it would not fit. Wrestled with this setup for hours under my hood, to finally take everything back apart and test fit it outside my truck. The set pin on the collector was installed too low, so it was impossible for the system to work. I ground off the bottom half of the set pin and then things could line up.
Note From Store Owner: We thank you for your feedback and we apologize for the difficulty you had during the installation. Our Customer Service Team looked up your order and will be reaching out to you to make this right. Our Quality Control Team was also alerted to ensure that this does not happen again.
