    Default "The" DPF removal write-up --> warning: this may be illegal, even for offroad use

    I'd like to gather all the useful info in one place about DPF removal.

    DISCLAIMER:

    The DPF was designed to allow the Duramax to comply with the extremely strict new diesel emissions regulations.
    Removing or modifying it is illegal in the US (even for offroad use)!


    Now on to the good stuff:

    For those that use their LMM for racing only and off-road, removing the DPF has shown substantial gains in fuel economy and power. However, it will cause serious complications. In this thread I hope to gather ALL of the correct information for people who decide to modify their LMM exhaust for whatever reason.
