Riffraff Diesel 321 Stainless Bellowed Up-pipe Kit for Ford 7.3L 94-Early 99
The ONLY 100% Made with Domestic Materials in the USA
These bellowed up-pipes are for the 94-Early 99 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 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.

*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.
Riffraff Diesel Performance is committed to 100% Made in the USA. All materials are from USA resources. Every bend, machine, and weld is performed in the USA. Every component is assembled in the USA.

Good product but they don’t give em away..just installed them recently so we’ll see how longevity is.
Took a little work to get them in only cause the pipes had to be loose to mate up to the turbo but besides that it was a easy install
Both pipes fit great and it actually comes with everything needed to complete the job.
I've had these installed for over a year now and absolutely no leaks! I have the early 99 F350 and these fixed my exhaust leaks perfectly. I stalled them with my transmission out while servicing the clutch, so it was an easy install. in the past year, I have looked down there for leaks, NOTHING! Worth the money!
They were shipped fast and appear to be very well made. They fit perfectly with no tweaking. I have no reason to believe that they won’t work and last just as long as the factory ones that cost twice as much.
I thought I would save some money and buy a set from another company that was selling some for less. My mistake! They were complete junk, wouldn't fit on the driver side at all, nothing I did could make them fit. Had to pay to send them back and bought these from Riffraff. I only wish I could post side by side pictures to illistrate what you get for just a little more money. It is obvious they time and care they take to manufacture these. Ever weld, ever bend fits up perfectly. I learned my lesson the hard way. Thank you Clay and team for getting these out same day and to me overnight so I could get my truck back on the road. You guys are the best. Peroid.
Fixed my leaking up-pipes, perfect fit, and the quality of the welds and bends are comforting to see. Glad to see something is still made right here in the USA.
The pipes fit very well on early 99 7.3 power stroke. No leaks after install
I can't say enough about the quality of the welds and bends on these pipes. Happy to support such a great American made product. Highly recommend to anyone with up-pipe leaks.
