Diesel exhaust leaks are a very common problem for Ford Powerstrokes. International Bellowed Up-pipes are definitely a worthwhile investment when exhaust leaks are found, and serve as a permanent fix for Ford’s “flawed” design. 

Installing Bellowed Up-pipes on your diesel truck is the perfect solution to the all too common diesel exhaust leak. The stock Ford up-pipes are designed using a crush donut gasket to seal the up-pipes into the y-collector. Over time, expansion and contraction cause the donuts to leak, hurting engine performance and mileage.

When your factory up-pipes leak you will start to see a loss of power, mileage and a gain in EGT’s. The International Up-pipe kit comes complete with everything you need to swap the leaking factory up-pipes for the new bellowed style, including hardware nuts and bolts
International Bellowed Up-pipes are exactly what you need to cure those leaking stock up-pipes. Diesel exhaust leaks aren’t a matter of IF, just a matter of WHEN. Your factory style up-pipes will start to leak, and when they do this is your permanent answer. Because International bellowed Up-pipes use a bellow rather than a donut gasket these kits won’t leak ensuring you are utilizing all your boost to spool the turbo.

The tell tail symptoms of an up-pipe leak are black soot present around the up-pipe/y-collector, and even soot deposits on the firewall and nearby engine components. Using aftermarket gauges, a 7.3L Powerstroke owner can also see a drop in boost and higher EGT’s.
The International up-pipes are bellowed and do not use crush donut gaskets. The bellows allow for expansion and contraction and rarely leak over time. Although not a diesel performance part (unless you get the ceramic coating), the International up-pipes are a worthwhile investment when exhaust leaks are found, and serve as a proper fix for Ford’s “flawed” design.

What makes The Diesel Performance Version unique is using Ceramic Coating. 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 7.3L Powerstroke turbo will spool up faster and more efficiently. A double coat to the outside of the pipes will protect them from rusting and it results in a much longer more 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.

What comes in the International Bellowed Up-Pipe Kit?The complete kit Contains:
• Collector, L/H Pipe, R/H Pipe, & Bolt Kit (2 gaskets, 4 short bolts, 4 long bolts, & 4 nuts)

A couple helpful tips before installing:
1) Soak all exhaust bolts and turbo clamps down with penetrating oil several times over a couple days prior to starting replacement. This will make the job go a little easier.
2)Disconnect the batteries.
3)You’ll be on top of the engine a lot. Get some blankets or a topside creeper for comfort.
4) Clean all component thoroughly prior to assembly.
