---tab Description--- Combining an EGR delete with a DPF delete comprehensively optimizes your Dodge Ram 6.7L diesel engine performance by eliminating two major restrictive emissions systems. This modification significantly improves power, efficiency, and engine longevity while reducing maintenance needs. Key Features Power Increase Removes exhaust backpressure from DPF, allowing turbo to spool faster Eliminates EGR’s recirculated hot gases, reducing intake air temperatures Typical gains: 15-30% more horsepower/torque (varies by tune) Improved Engine Health Prevents EGR soot buildup in intake manifold and valves Stops DPF-related regen cycles that dilute engine oil with fuel Reduces carbon deposits in combustion chambers Enhanced Fuel Economy No DPF regens wasting fuel (up to 2-3 MPG improvement) Cleaner combustion without EGR’s oxygen-depleted air Simplified Maintenance Eliminates DPF filter replacements ($1,000+ savings) No EGR valve/cooler failures to repair Reduces oil change frequency (no soot contamination) Thermal Management Lower EGTs (exhaust gas temps) without EGR’s hot gas reintroduction Reduced risk of turbo overheating during heavy loads Specification Exhaust Material T-409 Stainless Steel, it is magnetic. Thickness 2mm thick for long-lasting durability and heat resistance. Inlet Diameter 4.0"/5.0‘’ mandrel-bent construction Maximum flow efficiency, helping your diesel breathe easier Installation 2013-2018 Dodge Ram 6.7L Diesel EGR Delete Instruction 2013-2018 Dodge Ram 6.7L Diesel DPF Delete Instruction Tuner Required for Installation Installing a Dodge Ram 6.7L diesel delete pipe requires more than just swapping out hardware. When removing of the DPF, CAT, SCR, and/or DOC involves removing and eliminating emission related sensors. A DPF delete capable tuner is required to prevent any check engine light or diagnostic trouble codes from setting. ---tab How to Choose--- How to Choose DPF Delete? 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...
