The DIESELR Exhaust Manifold Kit with Up-Pipes for Duramax is built for 2001–2016 GM trucks running the 6.6L LB7, LLY, LBZ, LMM, or LML. If you’re done with restrictive factory manifolds and thin-walled up-pipes that fail under heat, this kit gives you what matters — thicker steel, smoother flow, and hardware that holds under pressure.
No hype. Just stronger parts that bolt in and perform.
Each DIESELR Exhaust Manifold Kit with Up-Pipes for Duramax includes:
- High-flow manifolds to reduce backpressure and restore consistent exhaust movement
- Thick-walled up-pipes built for extreme heat and vibration
- Gaskets and hardware for a proper seal and easy install
- Direct-fit design, no modifications needed
Built from premium materials, this system helps control EGTs and supports steady turbo response under load — ideal for towing, work, or off-road setups.
