Description
The PPE 116120000 Replacement Up-Pipes for your 2001-2004 GM 6.6L LB7 Duramax increase flow, and reliability. Even a stock Duramax can produce high temperatures and pressures that cause OEM up pipes eventually fail from constant temperature and pressure fluctuation.
PPE has taken the OEM replacement to a new level. PPE OEM Up-Pipes allow 53% greater flow over stock, and are a direct bolt-on to your factory manifolds. But unlike factory parts, PPE OEM Up-Pipes are manufactured from 11 gauge 304 stainless steel and include PPE's superior 304 stainless steel, internally-sleeved bellows that can take the abuse of high temperatures and pressures. Uses stock exhaust manifolds and hardware. Gaskets included.
Features:
- For Use With Factory Exhaust Manifolds
- Faster Spool-Up & Increased Performance
- Bolt-On Replacement (Federal Emissions LB7)
- Significant Reduction In Exhaust Back Pressure
- Free-Flowing Stainless Steel Inner Liner Bellows
- 2001-2004 Federal Emissions LB7 CARB EO# D-701-20
- Stainless steel 11-gauge .120-inch wall, 2-inch OD Up-Pipes
Application Note:
CARB EO# D-701-20 applies only to 2001-2004 LB7 Federal Emissions models.

Should flow better, but cant speak to performance as they're not in yet. Came with gaskets, but the mahle ones that came with the top end gasket set I ordered are higher quality.

Great Improvement
Mr. Duramax (S.D.) | April 16th, 2024
Great improvement in turbo boost! Suspected a small leak back there. These up-pipes took care of it. Too bad you can't see them anymore with those beautiful welds. Defiantly recommend to any Duramax owner. Order number 2248115

Put them on a 21 yr old truck. Had a broken bolt to deal with but other then that great fit. Cant put the heat shield back on, hope it isn't a problem. Thanks

So I originally bought some up pipes for 80 dollars less than these. Spent hours trying to force them on and they ended up cracking within 10 miles. Then I was like well, better just get the PPE pipes. I was infuriated with how well they fit. They literally fell into place. Anybody that has done up pipes on a D-Max knows how dreadful of a project it is. And these made it a breeze. Definitely buy them. Worth every penny. Great construction, great gaskets. Anything pre LML, order the driver side manifold with it! Makes install even easier in my opinion and increases flow by a lot!
