How to Choose a DPF Delete?
4'' vs 5'' Straight Pipe Comparison
- 4-inch Straight 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 Straight 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.
Driver Feedback Summary
- The 4" pipe works well for stock or lightly modified trucks and a quieter cabin.
- The 5" pipe is perfect for aggressive builds, deep-tone enthusiasts, and those maximizing exhaust performance.

- Improves mid-range power and throttle response
- Ideal for street builds using the stock turbo
Turbo-Back Delete

If you have basic mechanical skills and are comfortable working on your truck, you can definitely install this kit yourself. The EFI Live AutoCal V3 is plug-and-play, and we provide all the necessary components with clear instructions. However, if you’re unsure or lack the tools, consulting a professional is always a good idea.
Q: Will using this kit void my truck’s warranty?
Yes, installing this kit may void your vehicle’s warranty, as it involves removing emissions equipment. This kit is intended for off-road use only. Always check with your local regulations and consider your warranty status before proceeding.
Q: How does this kit improve my truck’s performance?
By removing restrictions from the EGR, DPF, and DEF systems, your engine can breathe better, resulting in improved combustion efficiency. This means more horsepower, better torque, and optimized fuel economy. Additionally, the reduced backpressure helps extend the lifespan of your engine components.

Absolutely! The EFI Live AutoCal V3 lets you switch between five power levels—0HP, 50HP, 75HP, 100HP, and 150HP—on the fly. Whether you’re towing heavy loads, cruising daily, or pushing for maximum performance, you’re in complete control.

This kit is intended for off-road use only. Removing emissions equipment may violate federal or state laws if used on public roads. Always check your local regulations before installation and use.
