L5P 6.6L Duramax 4"/5" DPF Delete Race Pipe for 2017-2025 Chevy GMC 2500HD 3500HD

Improve your 2017-2025 L5P Duramax diesel's fuel efficiency and performance with our DPF delete race pipe. All DPF delete pipes are made from T-409 stainless steel. For off-road and competition use only.

2017-2025 L5P Duramax DPF Delete Pipe Key Features

High-Flow 4" to 5" Expansion: Transitions smoothly from a 4-inch factory connection into a massive 5-inch straight-through race pipe, maximizing exhaust velocity and completely eliminating downstream restrictions.

Drastically Lower EGTs: Getting hot exhaust gases out of the system instantly prevents dangerous heat soak, protecting your pistons, head gaskets, and turbocharger during heavy towing or steep climbs.

Instantaneous Turbo Spool-Up: Removing downstream backpressure allows your VGT turbocharger to spin up effortlessly, eliminating lag and delivering razor-sharp throttle response from a stop.

End Frequent DPF Regen Cycles: Stop wasting raw diesel fuel and dropping your overall MPG on active DPF regeneration sequences designed to "burn off" soot.

Heavy-Duty Mandrel-Bent Steel: Smooth, constant-diameter curves ensure maximum structural integrity, zero flow restriction, and long-term off-road durability.

Unleash signature Duramax V8 Rumble: Unleashes a deep, aggressive, and powerful diesel exhaust note without the harsh, irritating cabin drone associated with low-quality pipes.

How to Choose Your 2017-2025 L5P Duramax DPF Delete Pipe

4'' vs 5'' 2017-2025 L5P Duramax DPF Delete Pipe Comparison

  • 4-inch Pipe: Produces a tighter, raspier exhaust note—especially noticeable at lower RPMs. Ideal for daily driving or mildly tuned trucks where excessive drone is undesirable.
  • 5-inch Pipe: Delivers a deeper, more refined tone with less high-pitch resonance. Better suited for high-output builds and towing applications, where improved exhaust flow is beneficial.

Types of 2017-2025 L5P Duramax DPF Delete Pipe Kits

DPF Race Delete (Style 01)

  • Removes only the DPF (retains stock downpipe)
  • Offers minimal performance gains but is the most budget-friendly
  • Best for cost-conscious users or avoiding emissions testing

Downpipe-Back Delete (Style 02, 03, 04, 06, 07)

  • Replaces the exhaust from the turbo downpipe back
  • Improves mid-range power and throttle response
  • Ideal for street builds using the stock turbo

Dual Exit (Style 05)

  • Splits into dual exhaust paths
  • Enhances cooling and flow for extreme conditions
  • Commonly used in heavy towing or competition setups

Muffler vs. No Muffler

With Muffler (Style 04)

  • Reduces exhaust noise for daily driving
  • Slight power restriction (~5–10 HP)
  • More likely to comply with local noise regulations

No Muffler (Style 01, 02, 03, 05, 06, 07)

  • Loud, aggressive exhaust tone
  • Unrestricted flow for maximum horsepower
  • Often not street-legal due to noise and emissions rules
  • Intended for off-road or race use only
