Product Details
2011–2016 Chevy / GMC Duramax 6.6L LML Up-Pipes (EGR Delete-Style) | Reliability + Spool Upgrade
When you’re deleting the EGR on an LML, the factory up-pipes become the weak link. These EGR delete-style up-pipes clean up the hot-side routing by eliminating the EGR feed takeoff and replacing a common leak-prone OEM component—so your Duramax stays tighter, spools cleaner, and tows more consistently.
Why Sasquatch Customers Add Up-Pipes With an EGR Delete
- Eliminates the EGR port (no block-off plate/gasket stack to seep or warp over heat cycles)
- Pre-turbo leak prevention—up-pipe leaks dump drive pressure before the turbo and can cause lazy spool, soot smell, and inconsistent boost
- More consistent towing performance—keeping exhaust energy where it belongs helps maintain steadier boost and EGT control under load
- “While you’re in there” labor savings—doing up-pipes during EGR removal avoids tearing it back apart later
- Cleaner, simpler hot-side setup—fewer sealing surfaces, fewer headaches
Benefits
- Helps reduce common exhaust soot leaks and ticking under load
- Supports quicker turbo response versus leaking/aging factory pipes
- Improves reliability for work trucks and tow rigs
- Ideal pairing with an EGR delete for a cleaner hot-side configuration
Fitment
- 2011–2016 Chevrolet Silverado / GMC Sierra 2500HD / 3500HD
- 6.6L Duramax LML
What’s Included
- Up-pipe set (driver + passenger)
- Any included sealing components/hardware are kit-dependent (see package contents on this listing)
Notes
- Up-pipes are a physical hardware upgrade—they do not “tune” the truck by themselves.
- If you are performing an EGR delete, proper calibration/tuning may be required depending on how your truck is configured.
