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.

    Up pipe kit

    Posted by Damian on Jun 14th 2020

    This product is amazing! Can’t believe how well it fit with no problems or hassles. I purchased xpd “ Xtreme diesel powers” up pipe kit and let me tell you it was a nightmare. Did not fit at all so the only thing I could do was take a loss on the money and go a different route and thankfully Riffraff makes a great product! I highly recommend this up pipe kit to anyone .
