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.
