Full DEF Delete Kit w/ EFI Live AutoCal V3 Tuner | Ram Cummins 6.7L | 2013-2018

DEF Delete Kit for RAM 6.7 Cummins 2013-2018

The 2013-2018 DEF delete kit for 6.7 Cummins is an All-in-One bundle designed for 2013, 2014, 2015, 2016, 2017, and 2018 RAM 2500 and 3500 pickups with the 6.7L Cummins diesel engine. The package combines an EFI Live AutoCal V3 tuner, custom SOTF tuning, a full EGR valve and cooler removal kit, and your choice of Delete Pipe, 4-inch Exhaust System, or 5-inch Exhaust System.

This complete system removes the restrictive factory DPF, DEF/SCR, and EGR components and matches the hardware changes with the correct ECU calibration. Buyers can configure the kit by year, transmission tuning, exhaust size, and muffler option rather than purchasing a fixed package.

Why Choose This Kit

• EFI Live AutoCal V3 tuning - vehicle-specific SOTF calibration with different power levels depending on whether TCM tuning is selected.
• Three exhaust options - choose a Delete Pipe, 4-inch downpipe-back Exhaust System, or 5-inch turbo-back Exhaust System.
• Optional TCM tuning - select None, 68RFE, or AISIN according to the truck’s transmission.
• Full EGR removal hardware - includes the EGR valve and cooler removal components rather than only basic block-off parts.
• Choice of exhaust sound - available configurations include straight exhaust or a muffler option for a more controlled exhaust note.

Vehicle Compatibility

This DEF delete kit for 6.7 Cummins is designed specifically for pickup fitment. It does not fit RAM 3500, 4500, or 5500 Cab & Chassis commercial trucks, which use different exhaust routing and tuning requirements. Older product references may also use the Dodge RAM name, but fitment should always be confirmed by model year, body configuration, engine, and transmission.

Kit Components

• EFI Live AutoCal V3 Tuner - flashes the custom ECU calibration and provides SOTF power selection for supported pickup configurations.
• Custom Tuning Files - calibrate the engine for the modified emissions system and provide the appropriate power levels based on the selected TCM option.
• EGR Valve & Cooler Delete Kit - includes the hardware required to remove the factory EGR valve and cooler assembly and stop exhaust gas recirculation through the engine.
• DPF & CAT Delete Pipe - replaces the factory particulate filter and catalytic aftertreatment section while retaining more of the original exhaust.
• 4" Exhaust System - T-409 stainless steel downpipe-back setup that connects to the factory downpipe. Replacing the stock downpipe is not required with this option.
• 5" Exhaust System - T-409 stainless steel turbo-back configuration that replaces the exhaust from the turbo connection rearward, including the factory downpipe.
• Muffler Option - available with supported exhaust configurations for customers who want to reduce exhaust volume while retaining freer flow.
• Installation Hardware - includes the clamps and related components needed for the selected configuration.

Tuning & Performance

The DEF delete kit 6.7 Cummins uses EFI Live tuning to match ECU operation to the physical removal of the factory DPF, DEF/SCR, and EGR hardware. The exact SOTF power levels depend on whether transmission tuning is selected.

Without TCM tuning, the package provides five SOTF settings ranging from Stock to +130 HP. When a supported TCM tune is selected, the calibration uses the +30, +60, +90, +120, and +150 HP power range. This distinction is important because the two configurations should not be presented as having the same tune levels.

After the hardware and tuning are fully installed, the truck no longer performs regeneration for the removed DPF, and the less restrictive exhaust path can improve throttle response and flow. Transmission tuning can also change torque management and shift behavior on supported applications. Actual power delivery, EGT, fuel economy, and overall performance depend on vehicle condition, load, gearing, tires, and selected tune.

Installation

Install the RAM 6.7 Cummins DEF delete kit in two stages: complete the EFI Live tuning first, then install the hardware. Connect the AutoCal V3, load the correct calibration, successfully flash the ECU, and clear the applicable emissions-related codes before removing the factory DPF, DEF/SCR, or EGR components.

Once tuning is confirmed, remove the factory aftertreatment hardware and install the selected Delete Pipe, 4-inch downpipe-back, or 5-inch turbo-back exhaust, followed by the EGR valve and cooler removal hardware. Basic hand tools, exhaust tools, penetrating oil, and safe access under the truck are required. Experienced DIY owners can complete the installation, while heavy corrosion, modified exhausts, or tuning problems may require help from a diesel shop.

Ordering Information

Before ordering, select the correct 2013-2017 or 2018 year group, then choose the TCM option that matches the truck: None, 68RFE, or AISIN. Next, select the exhaust configuration - Delete Pipe, 4-inch Exhaust System, or 5-inch Exhaust System - and choose the appropriate muffler option.

The tuning configuration also determines the available power levels, so the transmission selection must be correct before the custom tuner is prepared. EFI Live tuning is a vehicle-specific custom product, and the current product listing states that these orders are final sale and cannot be canceled or returned. The bundle currently includes free U.S. shipping, although individual parts of a multi-component package may arrive separately.

This product is intended for lawful off road and racing applications. Confirm vehicle fitment and applicable regulations before ordering or beginning installation.
