How to Choose DPF Delete Kit?

4” vs 5” Straight Pipe Comparison

When choosing a Dodge Ram 6.7L diesel delete pipe, the most common options are 4-inch and 5-inch straight pipes.
The 4-inch straight pipe delivers a tighter, raspier exhaust note—especially noticeable at lower RPMs—making it ideal for daily driving or mildly tuned setups where excessive drone is undesirable.
In contrast, the 5 inch straight pipe Dodge Ram 6.7L diesel offers a deeper, more refined tone with less high-pitch resonance. It excels in high-output builds and towing scenarios, where increased exhaust flow is beneficial.

Driver feedback suggests:

• 4”straight pipe is great for stock-to-lightly-modded trucks and a quieter cabin

• 5”straight pipe is perfect for aggressive builds, deeper tone lovers, or anyone maximizing exhaust performance

Different Types of DPF Delete

DPF Race Delete

• Only removes the DPF (keeps stock downpipe)
• Minimal performance gain but cheapest option
• Best for budget-focused or emissions-testing avoidance

Downpipe-Back Delete

• Replaces exhaust from the turbo downpipe backward
• Improves mid-range power and throttle response
• Good for street builds keeping stock turbo

Turbo Back Delete

• Full system replacement from turbo outlet
• Includes high-flow downpipe for maximum efficiency
• Reduces turbo lag and boosts top-end power
• Top choice for tuned/high-performance engines
