Product Features and Benefits

The DPF Delete Pipe for 2017-2024 GMC/Chevrolet 2500HD/3500HD L5P 6.6L Duramax Diesel is precision-engineered to replace the restrictive factory Diesel Particulate Filter (DPF). Crafted from high-grade stainless steel, it ensures durability and corrosion resistance, even under extreme temperatures. Its mandrel-bent construction optimizes exhaust flow, eliminating backpressure while supporting future performance upgrades like tuned exhaust systems or turbochargers.

By removing the DPF, this upgrade unlocks significant performance gains, including 20–40+ horsepower and 30–60 lb-ft of torque, while improving throttle response and fuel efficiency. The elimination of DPF regeneration cycles reduces engine strain, lowering long-term maintenance costs and extending engine life. Drivers will experience a deeper, more aggressive exhaust tone and smoother power delivery, ideal for towing, hauling, or off-road use. Built for reliability, this DPF Delete Pipe ensures compliance with off-road performance standards, making it a must-have for Duramax enthusiasts seeking to maximize their L5P engine’s potential.

Installation:

Installation typically takes about 1 hour using basic hand tools and can be done on the floor of your driveway or garage. Using a car lift may be faster. For vehicles with shorter wheelbase bed/cab configurations, some cutting may be required. This includes clamps, hangers, and hardware, but you may need to reuse some of the stock parts.

Tuner is required:

Deleting the DPF, CAT, SCR, and/or DOC requires eliminating emissions-related sensors. To avoid triggering a Check Engine Light or Diagnostic Trouble Code, a tuner with DPF Delete capability must be used.

Frequently asked questions
How much HP does a tuned and deleted L5P make?
Tuning your L5P will make the same power whether you have your emissions system removed or still on the truck. With supporting modifications like an intake, upgraded turbo, fuel pump, and injectors we have even seen trucks make over 600hp into the 630hp range on emissions in-tact trucks.
What is the life expectancy of a L5P?
With proper maintenance, the L5P is easily a 350,000-mile engine with some owners reporting well over that.
What are the benefits of deleting a Duramax?
With the L5P Duramax EGR DPF delete kit, you're not just removing parts – you're unlocking potential. By eliminating the restrictive EGR and DPF systems, your engine can breathe easier and perform better. Say goodbye to sluggish acceleration and hello to smoother power delivery.
Does the L5P burn oil?
The maximum oil consumption for the 6.6L Duramax™ Diesel engine (RPO L5P) is 2.36 liters (2.5 qt) within 379 liters (100 gallons) of fuel used. For heavy towing applications (9 mpg/26.1 L/100 km (Liters per 100 kilometers)), this correlates to a consumption of 2.61 liter (2.76 qt) per 1000 miles.
