Riffraff Diesel 321 Stainless Bellowed Up-pipe Kit for Ford 7.3L 94-Early 99
The ONLY bellowed up-pipes manufactured in the USA using 100% domestic materials.
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.
Unlike many aftermarket up-pipes that use lower-grade 304 or 409 stainless steel, every stainless component in our assemblies—including the tubing, heavy-wall bellows, and upper collars—is manufactured from certified aircraft-grade 321 stainless steel. Because 321SS handles significantly higher temperatures and have better tensile strength these can also be used in much higher horsepower and towing applications than other options on the market. 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.
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.
NOTE: Early 1999 are manufactured before 12/7/1998
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.

Much Better Than IH Up-pipes
The fitment is far superior to IH Up-pipes by far!
clearances & angles of pipe out of flange are so much better.
The bellows are not forced into weird bend-angles just on the install as the IH pipes were.
the bellow themselves are larger/more robust than the IH wimpy/skinny ones that can't take a hit!
Riffraff uppipe pricing make it a no-brainer on what UP-PIPES to use for your OBS
P.S.
i purchased/installed IH up pipes in 2011 FOR $$$.
the fitment was terrible.
had to stretch the bellows considerably using a heat gun to get them to fit onto the exhaust manifolds.
the angle of the pipe out of the flange on pass. side was just wrong...
this torqued the flange enough to develop a leak almost from the day I installed them. ...they leaked a bit when using engine brake, what a waste.
I surely hope Riffraff up-pipes last 15 years or more unlike the IH PIPES. -
Amazing Quality!
First off I have to say that this is why I buy American made products. From the welding, to the hardware, down to the packaging was perfect. I did a lot of research on the forums and saw a couple options from modifying a cheap chinese set for a Super Duty to buying some from a "company" that it looked like all they did was take old ones and half assed welded in a bellow.
I am SO glad I went with Riffraff instead. Install was great, and I bet these things will last longer than the whole truck does. Don't waste your time or money by getting cheap crap and then having to do it again later on. You can tell they took care in the design, engineering, and production of these pipes. -
Very nice set of pipes
Good quality, welds are amazing, no modifications needed... install was easy

best up pipes around fit like a glove
I emailed them because they had on their site that they where not in stock as to how long till they had them again and to my surprise the email I received the next day was saying they where ready to order cant beat that great company will be buying more from them

just buy them!
Well as you can quess....install is a royal pain in the ass. Nothing that cussing, beer and patients can't take care of. Hahaha I installed these on my e99 because my old up pipes fell out after loosening up the bolts to the manifold. Very impressed with the results!!!! I went from 1300°+ egt's down to 950° max egt's and a max of 7 psi of boost to about 23psi on flat ground wide open throttle. The bellowed up pipes made me and my truck happy again! The downside is that I was averaging 19.5 mpg on the highway before I installed them. After installing I'm averaging 17.6 mpg. I wonder if its because of the fact that the turbo is actually doing work now. Honestly I'm not sure. If someone has an answer, I'm all ears! But all in all the bellowed up pipes are the STUFF!!!!! Do it once, do it right, get your power back and drop your egt's to where they should be!

Quality product!
When I removed my turbo to make better access to install the riff raff cvd. I noticed I had an exhaust leak on my passenger up-pipe. I did some research and discovered some temporary repairs. During my research, these bellowed up-pipes where the permanent solution. The quality of this product is top notch. They lined up, installed perfect and work great. If you need to repair leaking up-pipe's, just bite the bullet and do it one time.
