Step 1 :

1.Disconnect batteries.Remove the passenger side inner wheel cover to drain the engine coolant, and disconnect the lower radiator pipe by removing the metal clip.
2.Loosen the hose clamps on the intake, and disconnect the MAF sensor connector.

Step 2 :

Pre install the charging tube using the provided baffle with O-ring.Note: Be sure to install two longer bolts on the front side of the pipe.

Step 3 :

1.Install the provided bracket onto the motor using a factory bolt and the M10 x 20 hex head bolt provided in the kit.
2.Install the exhaust block using the provided 20mm and 30mm bolts. All bolts will be installed from the back of the baffle.

Step 4 :

1.Re-install intake tube with thefront long bolts going through thepreviously installed support bracket.
2.Reverse earlier steps to re-installthe pcv hose, electrical wires, intakeand intake resonator.

Step 5 :

1.Use the newly provided coolant hose and hose adapter to connect the two coolant ports previously connected to the EGR cooler. Secure the hose with the provided hose clamp.
2.Replace the manifold bolts with the provided vertical bolts.

Step 6 :

1.Install the bracket. The M10 bolt will be screwed into the support bolt. Secure the transmission dipstick to the bracket using 1/4-20 bolts, nuts, and washers.
2.The bracket will hold the coolant hose connector in place.

DESCRIPTION

Product Overview

Over time, the factory EGR cooler is also highly prone to internal thermal cracking, allowing coolant to leak directly into cylinders—often resulting in catastrophic head gasket failures.
This LMM EGR Delete Kit completely isolates and removes the soot-recirculating loop. Your LMM will breathe nothing but pure, fresh oxygen, giving you smoother performance, lowered cooling loads, and complete peace of mind.

Key Features

Premium Billet Construction: CNC-machined anodized black aluminum blocks off the intake ports perfectly. Features premium, guarantee a lifetime leak-free seal under high boost.
No More Carbon Soot & Clogged Valves: Keeps abrasive carbon buildup out of your intake manifold. Your engine runs cleaner, meaning less wear and tear on your valves and internal components.
Prevent Costly Head Gasket Failures: Permanently deletes the leak-prone factory EGR cooler, completely eliminating the risk of internal coolant-to-exhaust leaks.
Lower Engine Operating Temps: Since hot exhaust gas is no longer running through the cooling system, engine coolant and operating temperatures drop significantly—reducing thermal stress on your entire cooling path.
Boosted MPGs and Performance: Burning clean air instead of dirty exhaust gas improves combustion efficiency. Most owners see an immediate improvement of 1–3 MPG, especially when hauling heavy loads.

FAQ

Q: Why does this kit include a "U-Shaped" coolant bypass hose?

A: When you remove the EGR cooler, you interrupt the flow of the coolant lines that used to feed it. The included heavy-duty silicone "U-hose" seamlessly loops the coolant flow back into the cooling jacket, maintaining proper coolant pressure and preserving your cabin heater's performance.

Q: Does the LMM Duramax EGR delete require removing the intake manifold?

A: No. While the LLY requires a deep top-end tear-down to remove the Y-bridge, the LMM's EGR system is mounted higher and further back on the passenger side. Although space can be a bit tight near the firewall, you do not have to pull your intake Y-bridge to complete this install.

Q: Can I run this EGR Kit with the stock exhaust, and upgrade to the 4"/5" pipe later?

A: Yes, You can install and run this EGR delete kit while keeping your factory exhaust completely stock. However, upgrading to 4"/5" Downpipe-Back Pipe later is highly recommended to fully uncork the engine, drop your EGTs by up to 200°F, and let your turbo spool up instantly.

Q: Why are the EGR systems different between early 2007 (LBZ) and late 2007 (LMM) trucks?

A: Stricter EPA emissions laws kicked in mid-2007. To comply, the late-2007 LMM engine had to recirculate much more exhaust gas, requiring a significantly larger EGR cooler and adding a restrictive intake throttle valve—neither of which exist on the simpler, early-2007 LBZ.
