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.
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.

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.

Worth every penny
I installed the stock replacement up pipes and donuts several months ago, so the pain and suffering of doing so is still pretty fresh in my mind. Installing the Riffraff bellowed up pipes was much simpler. Granted, I was already familiar with the tool list; however, everything seemed to fit much better. I did not pull transmission, the down pipe, or the transmission dip stick and had no issues getting the Riffraff pipes in.
Don't forget to order a new collector, if you need it.
The clearance between the new bellowed up pipes and the rear bolts of the turbo pedestal is less than the stock pipes, but it's particularly noticeable on the passenger side. On that side, I had to use a regular 10mm wrench, where I could use a ratcheting wrench with the stock pipes.
The bolts are included for both ends of the up pipes. I had no issues.
The welds on the Riffraff pipes are immaculate!
If you need new bolts for the turbo/collector connection, they are 10mm diameter x 30mm long x 1.5mm pitch class 10.9 flange bolts. If you can't find flange bolts, regular ones with washers will work. The studs are a bit longer, like 35mm. The factory studs are dual pitch, 1.25mm on the nut side and 1.5mm on the flange side. I just replaced with 1.5mm constant pitch and bought new nuts and washers.
I'm very happy with the purchase and would do it again. Wish I'd done it the first time...... -
Get ready to get dirty and bloody!
It was a pain in the arse to get the up pipes installed. Just finished the test drive well worth the money and the effort.

Quality Up Pipes
Finally went ahead and bought a set for my early 99 because the factory ones had been leaking for awhile. Very nicely built pipes that fit perfectly. Much cheaper than the International kit to. Truck is running good boost again and EGT's back where they should be. Highly recommend this product!

Good fitting and high quality
These up pipes did the trick on my 97 PSD...
The driver side pipe was a bear to install but the stock piece wasn't any easier to remove whole either. Very nice fitment and quality I would definitely purchase again -
up pipes
Must have in my opinion, fitment is great and top notch weld quality on them, I also installed the ebpv delete pedestal and makes reinstall of turbo a lot easier. Great product and cheaper than international ones

Well built!
I installed these up-pipes on my 96 OBS. I chose to install these pipes because I wasn't confident the stock pipes would not leak, even with new gaskets. I spent a lot of time wrestling with the turbo and pedestal, so I wanted to do the job right and not twice. The pipes are very well made and installed rather smoothly.
