Description

Unlock the true potential of your 2011–2015 Chevrolet Silverado & GMC Sierra 2500/3500HD Duramax LML with this complete 4″ DPF/EGR/DEF/CCV Delete Kit featuring the Mini Maxx V2 tuner . Crafted from premium T-409 stainless steel , this system replaces restrictive factory components, eliminating the DPF, EGR, DEF, and CCV systems to deliver smoother airflow, more horsepower, and improved fuel efficiency. The free-flowing 4″ race pipe removes the catalytic converter and DPF filter, while the EGR delete kit prevents soot buildup and valve clogging, extending the life of your Duramax. The included Mini Maxx V2 delete tuner gives you full control over your truck’s performance with adjustable power settings, diagnostic capabilities, speedometer calibration, and real-time digital monitoring. Many Duramax owners see gains of up to 4–5 mpg and significantly lower EGTs (Exhaust Gas Temperatures) for a cooler, more reliable engine. This all-in-one delete package also includes a CCV/PCV re-route kit , helping to eliminate oil smoke accumulation and keeping your intake system clean. Optional mufflers can be added for drivers who prefer a quieter, more refined exhaust note.
