Part Number:

Riffraff Diesel Bellowed Up-pipe Kit for Ford 7.3L 94-Early 99

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.

Kit Includes:

- 321 Stainless Up-pipes
- International Stainless Gaskets
- 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.

The ONLY 100% Made with domestic materials in the USA

    Thank you for the great service and the ability to get it right the first time !
    I needed these air freighted in (the tranny was out of the truck), arrived like clockwork. Fit perfect and the truck has a noticeable improvement in performance. I can hear the turbo again, it is boosting sooner than before. My salesperson was knowledgeable and polite.
    Thanks !!

    I can’t believe the quality of these welds. Perfect fit, and solid construction. Had an install question, and the tech at Riffraff called me back in under 15 mins, was pinpoint accurate and knowledgeable on the install and answered my question like he had installed tons of these. Can’t say enough about the product and customer service! You guys are my go to shop from now on.
