DPF Delete Pipe for LML Product Overview

Engineered exclusively for 2011-2016 GMC Sierra and Chevy Silverado 2500HD and 3500HD 6.6L Duramax LML diesel trucks, the LML DPF delete pipe removes the restrictive DPF and CAT to cut exhaust backpressure and recover fuel mileage. This 4 inch T-409 stainless, mandrel bent race pipe is a direct bolt on that needs a DPF delete capable tuner to run clean off road.

DPF Delete Pipe for LML Core Advantages

Recovered Fuel Mileage

A clogged DPF can drop a LML to about 13 to 14 mpg. Removing it with this 4 inch pipe ends the regen cycle that was burning extra fuel, returning combined mileage to roughly 18 to 19 mpg under normal driving.

T-409 Magnetic Material Truth

The pipe is 2mm wall T-409 ferritic stainless, which is magnetic, unlike the commonly assumed non magnetic T304. T-409 resists corrosion better than aluminized steel and costs less than T304, making it the best value exhaust metal for an off-road truck.

Lower EGT and Backpressure

Cutting the restrictive DPF and CAT drops exhaust backpressure, so the turbo spools sooner and throttle response sharpens. With no regen cycle the engine runs cooler and lasts longer under towing and heavy load.

Direct Bolt On with Ready Hardware

The pipe uses the factory hanger locations and ships with heavy duty lap joint clamps, stainless hangers, and O2 and EGT sensor bungs. Most installs finish in about one hour with basic tools, and only Short Bed or Single Cab trucks need a minor cut.

Ideal For the LML Duramax

  • Owners of 2011-2016 Chevy Silverado and GMC Sierra 2500HD and 3500HD with the 6.6L LML Duramax running an off-road delete tune.
  • Daily drivers and towers who want low end torque and recovered fuel mileage without a giant 5 inch system.
  • LML trucks with a clogged or failing DPF that want the regen problem gone for good.

LML DPF Delete Kit Specifications

  • Material: 2mm T-409 stainless steel, mandrel bent with no wrinkle bends.
  • Pipe Size: 4 inch for DPF and CAT removal.
  • Connection: V-band for 2011 to early 2015, 3-bolt flange for late 2015.5 to 2016.
  • Tuner: DPF delete capable tuner or ECU remap required.
  • Cab and Bed: direct bolt on for Crew Cab Long Bed, minor cutting for Short Bed and Single Cab.

Why Choose the DPF Delete Kit for LML

EGR Performance ships this pipe as a ready to bolt kit, not a bare tube, with clamps, hangers, and sensor bungs in the box so you are not hunting parts after delivery. The mandrel bent 4 inch route keeps low end torque and frame clearance that a 5 inch system can give up.

The standalone pipe is only the start. Build a full LML DPF delete bundle with a tuner and intake, up pipe, SOTF switch, CCV reroute, tuner harness plug, or CP3 kit, all selectable for this LML delete pipe. Pair it with a DPF delete tuner so the ECU runs clean after the emissions parts come off. Every order ships free in the US with a 1-year warranty, 45-day returns, and 24/7 support.

  • 2011-2016 Chevrolet Silverado 2500HD with the 6.6L Duramax LML.

  • 2011-2016 GMC Sierra 3500HD with the 6.6L Duramax LML.

Upgrade Your 6.6L Duramax LML Performance

Deleting the DPF and CAT lets the LML breathe free, dropping exhaust backpressure so the turbo spools sooner and the truck returns the fuel the regen cycle was burning. The 4 inch mandrel bent pipe keeps low end torque for towing and daily driving.

This is an off-road and competition part only. It needs a DPF delete capable tuner to run, and it is not for use on public roads. Check your V-band or 3-bolt flange connection and your tune before you order.

FAQs about LML DPF Delete Pipe

Which trucks fit the LML DPF delete pipe?

Fits 2011-2016 Chevrolet Silverado and GMC Sierra 2500HD and 3500HD with the 6.6L Duramax LML. Confirm your truck is an LML before ordering, since other Duramax years use different exhaust flanges. Both Chevy and GMC pickups are covered, but Cab and Chassis work trucks are not a fit for this pipe.

How do I know if I need the V-band or 3-bolt flange version?

Early 2011 through early 2015 LML trucks use a round V-band clamp off the turbo downpipe. Late 2015.5 through 2016 trucks use a 3-bolt flange. Check your connection before ordering: a round clamp means V-band and three screws means flange. Ordering the wrong style means the pipe will not bolt up.

Do I need a tuner after installing the DPF delete pipe?

Yes. Removing the DPF, CAT, SCR, and DOC also removes emission sensors, so the ECU needs a DPF delete capable tune to run. Without a tune the truck sets codes and can go into limp mode. Pair the pipe with an LML Duramax tune before you start the engine.

Will a magnet stick to the DPF delete pipe?

Yes. The pipe is made from T-409 ferritic stainless steel, which is magnetic, unlike the commonly assumed non magnetic T304. You can verify the material with a magnet. At 2mm wall thickness it resists corrosion better than aluminized steel and costs less than T304, making it the best value exhaust metal.

Should I choose a 4 inch or 5 inch delete pipe?

A 4 inch pipe keeps more low end torque and gives extra clearance from the frame and rear axle, which suits daily driving and towing with a lightly or moderately tuned truck. A 5 inch pipe flows more at high rpm but can lose a little low end response. For most LML owners the 4 inch is the smarter daily and tow build.

How much will fuel mileage improve after the DPF delete?

A clogged DPF can drop you to about 13 to 14 mpg. After removing it with this pipe, combined mileage often returns to 18 to 19 mpg. Big tires, heavy trailers, and driving habits can lower that, but the regen cycle that was burning extra fuel is gone.

Will this pipe fit my cab and bed length?

It is a direct bolt on for Crew Cab Long Bed trucks. Short Bed and Single Cab configurations need a minor cut to length during install. All necessary clamps and hangers are included, and the pipe uses the factory hanger locations so the fit stays clean.

How long does installation take?

The base pipe installs in about one hour with basic hand tools on the ground or in a lift. Clamps, hangers, and hardware are in the box. Bundles that add an intake pipe, up pipe, SOTF switch, CCV reroute, tuner harness plug, or CP3 kit take longer because of the extra components.

Is the DPF delete pipe legal for street use?

No. The pipe is for competition and closed course off-road use only and is not legal on public roads. It is also not for California emissions regulated vehicles, so check local and state rules before any off-road or competition use.

What is included and what warranty applies?

The box has the 4 inch mandrel bent T-409 delete pipe, heavy duty lap joint clamps, stainless hangers, O2 and EGT sensor bungs, and all needed hardware. EGR Performance backs it with a 1-year warranty against manufacturing defects and a 45-day free return. For help email service@egrperformance.com with your truck year, model, and order number.

LML DPF Delete Kit Installation Guide

The 4 inch DPF and CAT delete pipe bolts in with basic hand tools in about one hour. This is an off-road and competition install only, and the truck needs a DPF delete capable tuner to run with the emissions parts removed.

Remove the Factory DPF and CAT

  1. Park on level ground, let the 6.6L Duramax cool, and disconnect the negative battery terminal.
  2. Unbolt the DPF and CAT from the turbo downpipe and the exhaust, then lower them out of the truck.
  3. Fit the 4 inch mandrel bent pipe using the supplied lap joint clamps and stainless hangers at the factory locations.

Cut and Tune for Your Cab

  1. Crew Cab Long Bed trucks bolt the pipe straight in. Short Bed and Single Cab trucks need a minor cut to length before the final clamp.
  2. Torque the clamps and check the O2 and EGT sensor bungs are seated before the engine is started.

Base Pipe and Bundle Notes

The steps above cover the standalone DPF Delete pipe. Bundles that add a Tuner with Intake Pipe, Passenger Side Up-Pipe, Driver and Passenger Side Up-Pipe, SOTF Switch, CCV Reroute, Tuner Harness Plug, or CP3 Conversion Kit include extra components that bolt to the same LML exhaust and add install time.

Without a tune the truck logs emissions faults and can go into limp mode, so load the LML delete tune before starting the engine. This pipe is for off-road and competition use only, and is not legal on public roads or for California emissions vehicles. Check local rules before use.
