Smashed Performance Intake Resonator Delete Plate for Chevy/GM Duramax LML 2011-2016 — Direct-Fit, No Cutting

Smashed Performance's Intake Resonator Delete Plate replaces the stock under-hood resonator on 2011–2016 Chevy/GM Duramax LML 6.6L trucks for a cleaner fit and a more purposeful intake note.

Designed as a direct-fit replacement for the factory intake elbow resonator, this delete plate removes the bulky OEM unit without cutting, trimming, or modifying factory parts. It installs using the supplied hardware and aligns to the stock mounting points so you retain the intake elbow's original position while changing the resonator's function and appearance.

How does the delete plate install on my LML Duramax?

Installation is straightforward because the plate is engineered to match the factory intake elbow. No permanent modifications are required; the supplied bolts and gaskets allow you to reinstall the factory elbow exactly as before.

• Direct-fit to factory intake elbow mounting points
• Includes all necessary hardware for assembly
• No cutting, trimming, or drilling required
• Can be installed with basic hand tools in under an hour

What changes should I expect in sound and airflow?

Removing the OEM resonator alters the intake sound character, producing a more direct induction tone; airflow path remains intact since the delete plate preserves elbow alignment. The plate is not an intake filter—airflow gains are subtle and depend on the rest of your intake system.

• More pronounced intake sound compared with stock resonator
• Maintains factory elbow positioning for consistent airflow
• No air filtration or intake piping changes are included
• Compatible with other aftermarket intake upgrades

Will this delete plate affect engine sensors or performance tuning?

The plate is a passive replacement that does not alter sensor locations or engine management systems. It does not include electronics or tuning and is intended for owners who want cosmetic and acoustic changes while preserving factory sensor placement.

• Does not relocate or modify intake sensors
• No electronic components or tuning required
• Safe to use with stock engine calibration
• Works alongside performance hardware and aftermarket calibrations

Who is this for: The Smashed Performance Intake Resonator Delete Plate is for Duramax LML owners (2011–2016) who want to remove the bulky factory resonator for a cleaner engine-bay look and a more assertive intake sound while retaining the factory intake elbow's fitment. It's ideal for truck enthusiasts performing bolt-on upgrades who prefer simple, reversible modifications that require only basic tools.
