International Bellowed Stainless Up-pipe Kit 99.5-03

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.

    Up- pipes

    Posted by Joshua scritchfield on Dec 22nd 2019

    I have a 02 f250 and did a turbo upgrade. Do yourself a favor and replace them if you have your turbo off it definitely needs it especially if it's 20 years old mine were loose and leaking. These stainless up pipes are the real deal, spend the money you won't be disappointed..
    Riffraff diesel keep up the good work you guys are awesome!!

    Perfect fit!

    Awesome well made perfect fitting product! Never have tried any of the cheaper ones due to hearing too many complaints so I bought these ones and they fit perfect! Also opted for the black coating on them and they look awesome! Figured might as well do it right the first time cause it’s not a easy project. Wasn’t too bad to do though was expecting worse but I would say hardest part is getting everything else out of the way first.

    Up pipes

    Posted by Jason on Nov 12th 2019

    I replaced my turbo and pedestal so the up pipes were a no brainer. I pre assembled them prior to installing. Left the bolts on the manifolds loose so I could get the v band on easier. Also helps to leave the bolts on the turbo loose. In retrospect I probably should have replaced the manifolds as well.

    Bellowed up pipes

    These got rid of exhaust leaks and raised cruising boost 2-3 psi. I did have the transmission out when I replaced them, making the job easier.
