Riffraff Diesel Bellowed 321 Stainless Up-pipe Kit 99.5-03 7.3L

The ONLY 100% Made with Domestic Materials in the USA

*Please Note: The price will go down as soon as we find an AMERICAN Foundry to cast our collectors and can stop using the expensive USA Made Internationals

These bellowed up-pipes are for the 1999.5-2003 Powerstroke 7.3L and have been designed to replace the "donut" gasket that is prone to leakage and give you a more cost effective choice over International.

Our bellowed up-pipes are not only less expensive than International they are also much higher quality both in material and fitment.  Made from aircraft grade 321 Stainless Steel rather than 409 or even 304 allows for a lifetime product that won't rust or crack, ever.  Because 321SS handles significantly higher temperatures and have better tensile strength these can also be used in much higher horsepower and towing applications than the International brand. 321 Stainless Steel is immune to extreme temperatures, stabilized by Titanium, resists intergranular corrosion, and is high strength. Used for aircraft afterburners, exhaust manifolds, cabin heaters, flash boilers, firewalls, and stack liners. Not only is our tubing 321 Stainless but so are the custom thick wall bellows and upper collar. 

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 style 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 won't leak and will ensure you are utilizing all your boost to spool the turbo. When your factory up-pipes leak you will start to see a loss of power, mileage and a gain in EGT's. This kits come complete as pictured with everything you need to swap the leaking factory up-pipes for the new bellowed style, including hardware nuts and bolts.

Kit Includes:
- 321 Stainless Up-pipes
- International® Stainless Gaskets
- International® Collector Manifold
- OEM Ford Motor Company Install Hardware Kit

*Ceramic Coating Details -
The Turbo Black ceramic was formulated for exhaust temps up to 2000*F and will hold in at least 60% of the heat from radiating out under your hood. Not all black coatings will achieve that function. These coatings have been specifically formulated for use on military aircraft.

By retaining the heat energy your turbo will spool up faster and more efficiently. We double coat the outside of the housing to protect it from rusting and it results in a much longer attractive finish while retaining heat. The two main functions of the coating is appearance and longevity of your engine parts and gaining a more efficient running engine.


These kits are Made In The USA, and not overseas like other, lesser quality kits.

    No problems with install on this product. It's a job to install them but I had no issues with clearance, interference, or anything related to the kit. Exhaust leak is definitely gone now. Time will tell on the rest, but they sure look good and fit perfectly.

    USA Proud

    Posted by Jerry on Dec 20th 2021

    I am proud to purchase such an unapologetically USA made product. When others are trying to quietly sell more and more overseas cheap parts Riffraff stands out in the crowd supporting American trades and providing a product that is a great example of a quality part.

    Pricy but.....

    Yes their expensive, however the quality and build is the best and not something you want to have to replace a couple years down the road by buying the cheaper ones.

    Great up-Pipes and no more leaks

    Posted by Brian Papiez on May 3rd 2021

    I had the original up-pipes and as seen in many YouTube videos when I unhooked them from the exhaust manifold they practically fell out. These have solved my leaks and are so much quieter. They may be a little more expensive but they are 321 stainless steel and the welds are like art work. Riffraff takes great pride in their products and you can tell on these. For the amount of work it takes to replace these just spend the money on these and be done with it.

    Riffraff Up-Pipes

    Posted by Garrison Seeger on Mar 4th 2021

    These are the way to go, period. If you try to install the cheaper ones from other sites, you may regret it. Others have. Riffraff up-pipes go on slick as snot. Just follow their direction and all will end well. This was my first time installing up-pipes and I would not want to do it twice. The turbo has to come out to do this job. Perfect time to do them if you are adding a new pedestal and or turbo rebuild. Your already there at that point. I did not realize how bad my original up-pipes where leaking. The original up-pipes are known to leak any time after 50,000 miles or so. The smallest of leaks will effect your turbo performance. Final Fact Note: Turbo bolts (2) torque is 35-37 ft.lbs. Pedestal bolts (4) is 18 ft.lbs.
