2011-2016 LML Duramax All-In-One Kit (Tuning + Exhaust + EGR Delete)

LML Duramax All-In-One Kit - Everything In One Package

The complete do-it-yourself package for your 2011-2016 Chevy Silverado or GMC Sierra 2500HD/3500HD with the 6.6L Duramax LML. This all-in-one kit bundles everything you need to tune, open up your exhaust, and delete your EGR system - all in one order, one price, one shipment.

What's Included

Custom Tuning

• Custom Engine Tuning - Single-position calibration built for your specific truck, fuel, and power goals
• Choice of flash device: EZ Lynk AutoAgent 3.0 (cloud-based, easiest experience) or select "I Have My Own EZ Lynk AutoAgent" if you already have the hardware

Exhaust

• 4" Race Pipe option: DPF/CAT delete race pipe that bolts between your factory downpipe and tailpipe
• 5" 409 Stainless option: Full downpipe-back stainless steel exhaust system with mandrel-bent tubing and band clamps

EGR Delete & Up-Pipe

• Complete EGR Delete Kit - CNC billet aluminum block-off plates, stainless coolant reroute tubing, and silicone hoses
• LB7 Passenger-Side Up-Pipe - Eliminates the restrictive EGR riser for clean manifold-to-turbo flow

Why Bundle?

Buying the all-in-one kit saves you money compared to purchasing each component separately. More importantly, we build your tuning to match your exact setup - so your calibration accounts for the exhaust and EGR delete from day one. No guesswork, no mismatched tunes, no running a tune that doesn't know your EGR is gone.

Which Flash Device Should I Choose?

EZ Lynk AutoAgent 3.0 - Recommended for the smoothest experience. Cloud-based file delivery means you get tune updates pushed directly to your device over WiFi. No laptop required. Best for most customers.

I Have My Own EZ Lynk AutoAgent - Already have an EZ Lynk device? Select this option and we'll build your tunes for your existing hardware. No device shipped — just the tuning. Saves you $360 on the kit.

Which Exhaust Should I Choose?

4" Race Pipe - The budget-friendly option. This is a delete pipe that replaces your DPF and catalytic converter. Your factory downpipe and tailpipe stay in place. Great if you want to keep costs down and already have a factory or aftermarket downpipe.

5" 409 Stainless Downpipe-Back - The full system. Replaces everything from the downpipe back with 5" mandrel-bent stainless steel. Maximum flow, aggressive sound, and corrosion-resistant for long life.

About the LB7 Up-Pipe

An LB7 passenger-side up-pipe is included in this kit. It does NOT need to be installed, but it is highly recommended due to a common failure point in the factory passenger-side up-pipe. Installing the upgraded up-pipe improves reliability and prevents future exhaust leaks at the manifold-to-turbo connection.
