2016-2019 Turbo-Back DPF Delete Exhaust System for 2.8L LWN Duramax (Colorado/Canyon)

Unleash the hidden potential of your mid-size diesel. The SPEtuner DPF Delete Race Pipe is a precision-engineered performance upgrade designed specifically for 2016–2019 Chevy Colorado and GMC Canyon trucks equipped with the 2.8L Duramax LWN turbo diesel engine.

The factory emissions system on the 2.8L Duramax is surprisingly restrictive, often forcing the small-displacement engine to struggle against its own exhaust backpressure. By removing the bulky and clogged Diesel Particulate Filter (DPF), this race pipe allows your turbo to spool up significantly faster, sharpens your throttle response, and transforms your truck into the responsive daily driver it was meant to be. Experience true fuel efficiency and the unmistakable whistle of a free-breathing Duramax.

Note: For Off-Road/Race Use Only – Not for use on public roads.

Key Features

• Unrestricted Exhaust Flow: Completely replaces the restrictive, soot-clogged factory DPF unit, allowing your 2.8L engine to breathe effortlessly and reducing exhaust backpressure to near-zero.
• Instant Turbo Response: With the downstream bottleneck gone, your turbocharger spools up almost instantly, curing the "sluggish" feel often reported in stock LWN engines.
• Maximize Fuel Economy (MPG): Eliminate the frequent, fuel-thirsty DPF regeneration cycles that waste your diesel and drop your fuel efficiency. You will see a noticeable increase in real-world MPG after a proper delete tune.
• Lower Operating Temperatures: By allowing heat to exit the system immediately, you keep your engine internals, turbo exhaust housing, and oil temperatures significantly cooler during daily commutes and towing.
• Enhanced Durability: Prevent soot-related contamination of your engine oil and intake system, extending the life of your vital internal engine components and fuel injectors.
• Signature Duramax Whistle: Unleashes a crisp, clear turbo whistle and a deeper, more aggressive exhaust note that stock trucks simply cannot produce.

---tab FAQ---

FAQ

Q1: What does deleting the DPF on a 2.8L Duramax do?
A1: Deleting the DPF (Diesel Particulate Filter) on your 2.8L Duramax removes restrictions from the exhaust system, resulting in better airflow, lower exhaust gas temperatures (EGTs), improved fuel economy, and increased horsepower and torque. It’s a popular off-road performance upgrade.

Q2: Is a DPF delete legal on my 2016–2019 Duramax?
A2: No, DPF delete kits are intended for off-road or race use only. Removing emissions equipment on a street-driven truck is illegal in many regions, including the U.S. and Canada. Always check your local emissions laws before purchasing or installing.

Q3: Will this turbo-back exhaust fit my stock Duramax without cutting or welding?
A3: Yes. This system is designed as a direct bolt-on replacement for your OEM exhaust. It includes all necessary hardware, pre-welded hangers, and heavy-duty clamps to simplify installation with no cutting or welding required.

Q4: Do I need a tuner after installing a DPF delete exhaust?
A4: Yes. After deleting the DPF, your truck's ECU will need to be reprogrammed to disable emissions-related trouble codes and ensure proper engine performance. Compatible tuners include EZ Lynk, HP Tuners, and EFI Live.

Q5: Does this DPF delete kit come with everything I need?
A5: Yes. The kit includes the full 3" turbo-back exhaust system, muffler, DPF delete pipe, pre-welded hangers, stainless clamps, and all necessary mounting hardware for a complete installation.

Q6: Will this work on a Cab & Chassis Duramax model?
A6: No. The Cab & Chassis frames are longer and require a specific exhaust system. Please check our Cab & Chassis-specific kits or contact us for help selecting the correct system for your truck.
