These ODAWGS bellowed up-pipes are the perfect replacement for those old stock non-bellowed up-pipes that are very prone to leaking.

These high quality up-pipes Made from aircraft grade 321 Stainless Steel, for a lifetime product that won't rust or crack! Because 321SS handles significantly higher temperatures and have better tensile strength these can also be used in a wide range of Truck usage. From daily driving to drag racing, these bellowed up-pipes will suit your trucks needs.

Because these 7.3 Powerstroke up-pipes remove the factory style donut gasket, they achieve a much greater seal and help eliminate and reduce any exhaust leaks that can slowly creep up on stock stock up-pipes. Exhaust leaks can rob your engine of horsepower, slow spool up times and spike EGT's. You can literally feel the difference in your truck. This kit comes will all hardware and gaskets needed to install on your truck.

This Kit Includes:

- 321 Stainless Up-pipes
- Stainless Gaskets
- OE Install Hardware Kit

They kinda fit.

Up pipes are inherently a pain in the ass to deal with, but these are a bit rough. I've done my fair share of 7.3 up pipes, and all have fit better than these. Even with every bolted joint loose, and the turbo pedestal loose, the flanges did not align.
Tried the order of operations in that video and it was worse. Tried adjusting the "clocking" of the up pipes to adjust flange angle and was in the same position. I did finally get all 4 bolts into the flange, but it was a major chore and left everything preloaded. Now I know someone would say, "that's why the bellows are there", In this case the issue wasn't the length of tube, but the side deflection. The bellows on mine didn't allow deflection side to side.
Whatever tooling is used for these, it needs fixed/adjusted.
I bought these vs the Chinese knock-offs to avoid stupid issues like this.
