PPE High-Flow Exhaust Manifold & Up-Pipe Kit - Raw Finish (2007.5-2010 GM 6.6L Duramax LMM) - (116111800
Overview
The factory exhaust manifold and up-pipe assembly on the 2007.5-2010 GM 6.6L Duramax LMM is known for creating excess back-pressure and elevated EGTs. PPE's High-Flow Exhaust Manifold and Up-Pipe Kit replaces these restrictive components with a stronger, smoother-flowing system designed to improve turbo response, reduce heat, and support higher performance demands.
High-Flow Manifold Construction
The manifold is cast from high-sil moly iron for excellent durability and heat resistance. Its optimized internal geometry promotes smoother exhaust flow, helping lower EGTs and improving turbo spool-up. A ceramic-coated version is also available for those who want enhanced thermal control and long-term corrosion protection.
Free-Flow Up-Pipe Design
The included up-pipes feature free-flowing stainless steel inner liner bellows and are constructed from 11-gauge (.120-inch wall) stainless steel with a 2-inch outside diameter. Internally sleeved bellows made from aircraft-grade 304 stainless steel increase durability and flow capacity under high heat and high boost conditions.
Performance & Reliability Benefits
Together, the manifold and up-pipe system is engineered to maximize exhaust flow, reduce thermal load, and improve overall engine efficiency. The result is quicker turbo spool, lower EGTs, and more consistent performance whether towing, daily driving, or running performance upgrades.

- GTIN: 840171208979
Optional Ceramic Coating
PPE's ceramic coating option adds a thermal barrier that slows heat absorption and reduces surface temperatures. This improves flow efficiency, lowers EGTs even further, and protects the manifold from moisture, road salts, oil, fuel, and other corrosive elements. It also keeps the manifold looking clean for years.
Upgrade Path
Pair this kit with a PPE 3-inch 304 stainless steel downpipe for a complete high-flow exhaust solution. For maximum performance, combine with PPE's ceramic-coated manifold option and additional 304 stainless components.
