International Bellowed Stainless Up-pipe Kit

International Bellowed Stainless Steel T409 Up-pipes 1837872C93 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 with everything you need to swap the leaking factory up-pipes for the new bellowed style, including hardware nuts and bolts.

*Ceramic Coating Details $140 (Optional) - 
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 pipes to protect them 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.

  1. First mod done 5 Star Review

    Posted by on Nov 4th 2017

    I did these back in march of 2016 and it was the first thing I did on my 02 Ex. It pays for itself and I think the ceramic coating looks great and works great. These are a must for a 7.3 engine. Always the fast shipping and great price form Riffraff.

  2. Perfect fit! 5 Star Review

    Posted by on Oct 27th 2017

    The stainless up-pipe fit perfectly and restored a lot of lost horsepower due to the old leaking up-pipe. Took me about 5 hours to complete the install by myself, probably could have saved an hour or so if I had some help. Great product.

  6. Worth EVERY penny!!! 5 Star Review

    Posted by on Sep 2nd 2017

    Easy install, even for a woman that is self taught about the ways of the beautiful beast that is the 7.3L. It has brought the performamce level of my 2002 Excursion 4x4 back to where it should be and a little beyond, in my opinion. These are worth every penny and are a great investment. If you love your truck and the true performance that these engines can produce you will make this investment. Trust me you will NOT be disappointed.

  7. good investment 5 Star Review

    Posted by on Aug 31st 2017

    lots of cheaper options out there, but the quality of these pipes are fantastic: fitment, weld quality, hardware, aesthetics ect.. Spend the extra money and buy the last set of up pipes you'll ever need.

    I concur with all of the reviews; the reviews really sold me on paying the extra money for this high quality product. Thanks Riff-Raff and the customers whom provided feed-back.

  8. 100% Worth The Money 5 Star Review

    Posted by on Jun 18th 2017

    You can't go wrong with these up-pipes. Fit was perfect. Only took me about 3 hours to install and it was my first time. Welds and bellows are perfect. Well worth the extra money over the dormans.

  9. Fell right in 5 Star Review

    Posted by on May 12th 2017

    These were great. Took a little bit of convincing myself to purchase, but glad I did. They are a bit pricey but worth it. No fitment issues and no more leaks from those crappy stock pipes with the donut gaskets.

  10. The Only Up-Pipe Option 5 Star Review

    Posted by on May 12th 2017

    I recently bought a 1999 F-350 Ambulance that is begin converted into a mobile command center/overland vehicle. The up-pipes were leaking and a Dorman replacement was given with the purchase. I wanted to replace the pipes with something I knew I would never have to worry about.

    This kit is awesome. Fits perfect and has more bellows than the Dorman part. Not to mention the casting/machining was more precise.

    Thanks Riffraff!
