Product Details

Product Name: Down Pipes
Manufacturer: MBRP
Fitment Notes: 2011-2016 GM Duramax

The MBRP 3" Turbo Downpipe eliminates the restrictive factory downpipe in your GM 6.6L Duramax LML. Featuring a mandrel bent aluminized steel construction, the MBRP 3" Turbo Downpipe provides a smoother flow from the turbo resulting in lower EGT's, increased performance, throatier sound, and faster turbo spool-up.

Each Downpipe is coated with a satin black high-heat coating and wrapped with a high-heat thermal wrap for added protection. Featuring CNC machined flanges, this Downpipe is a direct bolt-on replacement, and is manufactured with precision bends for the perfect fit that you've come to expect from MBRP.

Features:

  • Reduced Temperatures
  • Increased Performance
  • Coated & Heat-Wrapped
  • Aluminized Steel Construction
  • Richer Diesel Sound

    No, you will have to modify a 4" downpipe.
