The XDP OER+ Series Bellowed Up-Pipe Kit XD178 will fix a common issue that robs power from the engine in your 1999.5-2003 Ford 7.3L Powerstroke. 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. These power-robbing exhaust leaks lessen the turbo’s effectiveness, reducing performance, efficiency, and overall drivability.

The XDP OER+ 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. The exhaust collector features a ceramic coating and the up-pipes are manufactured from stainless steel for increased durability. This kit includes all the hardware and gasket you need for a direct-replacement installation. 

  • Bolt-On Replacement
  • Stainless-Steel Up-Pipes
  • Ceramic Coated Exhaust Collector
  • Eliminates Factory "Donut" Gaskets
  • Includes Gaskets & Hardware For Installation
  • Bellowed Design Allows For Expansion & Contraction

These are worth the extra money. Don't waste your money on cheap ones from Amazon like I did and then ended up sending them back. The difference between the cheap ones and these was the y collector. This one is machined much more precise. These also helped lower my egt's by 200 degrees and I thought I only had a couple of small leaks. They really made a difference! Definitely worth all the pain in installing them. Order #1895330

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 )
