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. 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
- Stainless Gaskets
- OE 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

  1. Obs bellowed up pipes. 4 Star Review

    Posted by on Apr 17th 2017

    Quality was awesome. Driver side went on with little effort but passenger side was a pain. The problem was the bellowes was really close to the flange of the bolt and made them almost impossible to get started. If I didn't have the transmission already put I probably wouldn't have gotten them in. Once they were started and threaded in pass the bellow it went together great. All in all I wouldn't hesitate to buy them again.

  2. Amazing Quality! 5 Star Review

    You can really see the time and effort they took with these pipes. Smooth bends, perfect tig welds, and ford hardware. Riff raff really sets the standard on US made parts. So glad i don't have to worry about up pipes again!

  3. Fits Great. 5 Star Review

    Posted by on Apr 10th 2017

    As advertised and just cheaper than International bellows.

  4. Great product 5 Star Review

    Posted by on Apr 2nd 2017

    Installed on my 1997 and couldn't be happier, I did a rebuild on my turbo so I replaced these as well, before I was like 12psi on a good day now I'm hitting 25-30psi. I did a few things all at once, put in a wicked wheel 2 and 1.0 turbine housing along with 4" staight exhaust. Removing and installing was a challenge almost everything was rusted in or snapped when removing so I ordered and replaced EVERYTHING down to the last nut and bolt, my truck was neglected before I got it so I played it safe.

  5. Perfect fit 5 Star Review

    E99's are getting old, glad you are still making these.

    My up pipes work great. I loved the instructions.

  9. Only The Best From RiffRaff 5 Star Review

    Posted by on Dec 21st 2016

    I chose to get the ceramic coating, they looked great and where packed very well. More importantly they fit great and don't leak. I was having troubles clearing the drivers firewall on install but a quick call to RiffRaff and they gave me the guidance to make it happen (loosen the drivers engine mount and jack the motor up an inch or so). Thanks again.

  10. Quality product! 5 Star Review

    Posted by on Nov 21st 2016

    I can't comment on how much of a difference these alone made over my stock leaking up pipes, because I fixed a leaking exhaust manifold and upgraded the turbo at the same time. But I can say, some serious effort was definitely put into these up pipes and it shows. Fitment is spot on, and the quality is top notch!! Money well spent, especially knowing I'll never have to worry about exhaust leaks again. I would definitely recommend them to anyone who has leaking up pipes!
