Thumbnail Filmstrip of LML Duramax 3" Turbo Down Pipe w/3 bolt flange style connection MBRP GM8428 Images
Specialized Performance for Late-Model LML Duramax
Maximize the true potential of your 2015.5 to 2016 GM 6.6L LML Duramax—specifically those equipped with the 3-bolt flange style connection—by upgrading to the MBRP 3" Turbo Down Pipe (Manufacturer Part # GM8428). The restrictive factory down pipe severely limits your engine's efficiency right off the turbo. This direct replacement down pipe from MBRP is engineered to eliminate that bottleneck, delivering a remarkable 20% greater exhaust flow over stock. This significant improvement translates directly into tangible performance gains, providing up to +21 horsepower and +24 lb/ft of torque, along with noticeable fuel economy improvements and a deeper, richer diesel sound. Additionally, the design promotes greater heat retention within the exhaust stream for optimal performance and is engineered to not affect the factory DPF system or the UREA injection system.
- Application: Direct fit for 2015.5-2016 GM 6.6L LML Duramax models.
- Fitment Note: Only works with the specific 3-bolt flange style connection at the catalytic converter.
- Performance Gains: Expect gains of up to +21 HP and +24 lb/ft torque.
- Flow Efficiency: Provides 20% greater flow over stock for reduced turbo lag and better performance.
- Thermal Design: Engineered for greater heat retention within the exhaust stream.
- Emissions: Will not affect the DPF system or the UREA injection system.
- Acoustics: Contributes to a richer diesel sound.
By choosing this MBRP Turbo Down Pipe, you are investing in reliable performance and a better-running engine. However, because this product replaces the restrictive factory downpipe, please be advised that the removal of OEM catalytic converters may be a violation of emissions laws in your jurisdiction. It is your responsibility to ensure the intended use of this product complies with all local regulations. This product is not for sale or use in the state of California. If your LML Duramax features the 3-bolt flange, this specialized down pipe is your direct path to unlocking greater power and better fuel economy
