FAQs
Each full kit includes an OBD II flash delete tuner, EGR valve and cooler delete components, your choice of a DPF delete pipe or full 4″/5″ exhaust system, heavy-duty clamps and hardware, plus an optional muffler for tone control. All pieces are engineered for clean installation and long service life.
To properly delete an L5P Duramax, you’ll need a few key components that work together as a complete system. Skipping any of them usually means poor tuning or exhaust issues later on. Here’s what’s required:
- OBD II tuning interface for custom calibration
- Full EGR valve and cooler removal kit
- DPF delete pipe or full 4″/5″ exhaust system
- Clamps, hardware, and optional muffler
LML Duramax delete kits usually come with the Mini Maxx V2 tuner offering multiple modes - Stock, Tow, Street, Performance. They include 4″ T-409 stainless delete pipes.
L5P delete kits rely on OBD II flash tuning and come with 4" or 5" exhaust options, with SOTF tuning available for fast plug-and-play use.
Pick based on your engine generation (L5P, LML, LMM, LBZ) and what you want out of it - more torque, horsepower, a deeper exhaust tone, or better durability under towing or racing conditions.

Yes. The DPF delete tuner Duramax model recalibrates the ECM, clears codes, and optimizes performance once emissions parts are removed.
Yes, if you’re comfortable with tools and follow the provided installation instructions. A pro install is still the best bet for perfect alignment and long-term reliability.
Yes, it will. Removing DPF, DEF, and EGR restrictions cuts backpressure, lowers temps, and stops common failure points. The result - cooler operation, better mileage, and stronger reliability under load.
For off-road or racing setups - absolutely. The gains in power, torque, and throttle response are noticeable. The truck just feels freer, stronger, more alive.
Yes. Once emissions parts are removed, factory warranties no longer apply.
No, DEF delete kit Duramax is for off-road, race, or export use only. Using it on public roads violates EPA and Environment Canada emissions laws.
