A complete delete kit includes the essentials to remove major bottlenecks: EGR delete plate or kit, DPF delete pipe, and DEF tank delete support.
These kits restore airflow, cut regen cycles, and reduce engine temps under load. If you're after reliability and better towing efficiency, this is where it starts.

LML EGR Delete – Benefits & Options
EGR systems recycle hot exhaust gases back into your intake. That means soot, heat, and eventually, clogged components.
Deleting the EGR system helps keep your intake clean and improves combustion. You’ll notice quicker throttle response and more consistent boost.
Pair your EGR delete with a PCV reroute for the cleanest engine setup.
Downpipe, Up Pipe & Exhaust Upgrades for LML
LML Downpipe – Improve Turbo Flow
Stock downpipes choke the turbo. Upgrading to a 3" or 4" high-flow downpipe reduces backpressure and boosts turbo spool-up.
You’ll feel the difference on hills and when passing. Plus, it gives the truck a deeper, more aggressive sound.
We offer stainless steel downpipes built to handle high temps and heavy use.
Upgraded Up Pipes for Durability
The factory LML up pipes are thin and prone to cracking under heat. That’s the last thing you want during a long haul.
Upgrading to high-flow, heavy-wall up pipes ensures better durability and smoother exhaust flow.
These pair great with a downpipe and EGR delete for a full exhaust refresh.
Get the Most From Your Delete Kit with a Tuner
Best Tuners for LML Duramax (2011–2016)
Deleting without tuning? Don’t bother. A tuner is required to recalibrate your ECM and prevent codes or limp mode.
Our recommended tuners for LML include EFI Live and EZ Lynk. Both offer custom options and delete support.
Choose a tuner that matches your driving goals: towing, daily use, or high-performance builds.
Reroute Kits & Performance Add-ons
LML PCV Reroute – Protect Your Engine
Crankcase vapors carry oil mist that gunks up your intake system. A PCV reroute fixes that.
It vents blow-by gases safely without sending them back into the turbo system. Simple, effective, and cleaner all around.
This mod is a perfect companion to EGR deletes.

FAQ
What’s included in a complete LML delete kit?
Typically, it includes an EGR delete kit, DPF delete pipe, DEF tank support, and necessary clamps. Some kits also include up pipes or downpipes for full exhaust refresh.
Will deleting EGR improve MPG on my LML Duramax?
Yes. Removing EGR improves airflow and combustion efficiency. Most users report a 1–2 MPG gain under normal driving conditions.
What’s the best tuner to pair with delete kits?
EZ Lynk and EFI Live are the go-to choices. Both support custom tunes for delete configurations and offer shift tuning as well.
Can I run a downpipe without a full delete?
Technically yes, but we don’t recommend it. The system still relies on sensors downstream, and you’ll likely throw CEL codes without tuning.
Do I need a PCV reroute after deleting EGR?
You don’t need it, but it’s highly recommended. It keeps your intake system cleaner and works synergistically with EGR delete mods.
