    In 2015, the Duramax models have two versions. The truck also got a body style upgrade in the 2015.5 versions. The earlier version have V-clamps, if this is your truck, select 2011-2015. The later version has the 3 bolt flange, if this is your truck, select 2015.5-2016. Selecting the wrong year will result in receiving the wrong DPF delete pipe. Email us if you aren't sure

        LML Delete

        The Diesel Dudes were great . Delivery was fast and the tunes are great. The only gripe if I had one would be maybe add some directions with the kits.


        Thank you for the feedback, we are working on video install instructions to email customers. For now, we just refer people to great videos on Youtube that help with installs
