---tab Description---

A complete 3″ Turbo-Back DPF delete exhaust system for 2016‑2019 LWN 2.8L Duramax engines. Made of durable 409 stainless steel, it replaces the factory DOC, DPF, and tail section to reduce backpressure, improve turbo response, and deliver a deeper diesel sound. Ideal for off‑road, performance, and heavy‑duty use.

Key Features

• Complete Turbo-Back System:  Provides a one-piece, integrated solution replacing the downpipe, mid-pipe, and all necessary hangers/hardware—no welding or custom fabrication required.

• Muffler Delete Design:  Eliminates the muffler for maximum exhaust flow and a more direct, powerful, and deeper diesel sound characteristic.

• Performance & Durability:  The 3-inch diameter 409 stainless steel construction reduces backpressure, lessens strain on the turbo and engine, allows for easier torque release, and offers superior corrosion resistance compared to factory piping.

• Direct Bolt-On Installation:  Designed to utilize factory mounting points for a straightforward installation process.

• Optimized for Tuning:  Works ideally with ECU-tuned or modified vehicles to maximize performance gains.

• Suitable for Demanding Use:  Recommended for off-road, towing, racing, and non-highway environments (e.g., farms, construction sites) where durability and performance are critical.

Specification

• 3" Turbo-Back Exhaust system.

• T409 Stainless Steel

• Single Side Exit

• Easy Installation - Mounts to OE Hangers

Installation

• Estimated install time: ~1 hour with basic tools; faster on a lift.

• Kit includes clamps, hangers, and hardware—some OEM pieces may be reused.

• Tuner Required: DPF, CAT, SCR, and DOC deletions disable emissions sensors. A tuner with Powerstroke DPF delete capability ensures no check-engine lights or fault codes.
