About Exhaust Systems and Delete Pipes
Exhaust Systems and Delete Pipes
DPF Delete's collection of diesel performance components includes DPF and CAT delete pipes, 4" SCR urea race pipes, turbo-back and downpipe-back competition exhaust systems, EGR delete kits, and cold air intakes. Fitments cover Ford Powerstroke, Ram Cummins, GM Duramax, Mercedes Sprinter, and Nissan Cummins engines. Every product is sorted by engine model and vehicle year, so you can find the right fit quickly.
The parts are built from high-grade materials to increase exhaust flow, add horsepower, improve fuel economy, and hold up over time. Upgrade your diesel truck for more power, better efficiency, and a longer service life.
Engineering and Design Advantages
- Maximum flow: 4" and 5" mandrel-bent piping cuts backpressure and adds power from the mid-range to the top end.
- Faster spool, lower EGTs: Better exhaust routing improves turbo scavenging and lowers exhaust gas temperatures under heavy load.
- Better airflow: EGR delete kits and cold air intakes work with the exhaust upgrades to improve airflow through the whole engine.
- Distinctive sound: An aggressive diesel tone, in straight-pipe or muffled configurations.
- Precise fitment: Direct bolt-on installation with factory-style hangers and brackets.
- Rugged construction: T409 or T304 stainless steel resists corrosion and high temperatures.
Collection Includes
- DPF and CAT delete pipes
- 4" SCR urea race pipes
- Turbo-back and downpipe-back competition exhaust systems
- EGR delete kits
- Cold air intakes
- Mufflers and components, including the T409 4" stainless steel diesel muffler
Key Performance Specifications
- Diameters: 4" and 5" systems, depending on the application
- Construction: T409/T304 stainless steel with mandrel-bent tubing
- Configurations: Turbo-back, downpipe-back, and delete pipe layouts
How to Find the Correct Part
- Match your engine and exact model year to the product title.
- Choose a delete pipe, a turbo-back system, or a downpipe-back system.
- For exhaust systems, choose a 4" or 5" diameter, then a muffler or straight-pipe option.
