Performance Comparison: Before and After

DPF Delete Pipe Description

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.

Types of DPF Delete Kits

DPF Race Delete

• 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

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