Maximize Your Ride: Comparison of Cummins Performance Kits from TruckTok for Guaranteed Fast Shipping

Upgrading a late-model diesel engine requires precise hardware to eliminate factory restrictions and restore mechanical efficiency. For operators needing reliable performance modifications, TruckTok provides the exact components required for dedicated off-road builds. This guide compares the primary Cummins performance kits available from TruckTok to help technicians and DIY diesel truck owners select the correct upgrades for their specific engine platform.

Comparing Cummins Performance Upgrades

1. TruckTok 6.7L Cummins DPF Delete Pipe - Full exhaust restriction removal

The exhaust system on a factory 6.7L Cummins contains heavy restriction points that trap heat and limit turbo spool. The TruckTok DPF delete pipe directly replaces the factory diesel particulate filter and catalytic converter sections. By installing this straight-pipe section, exhaust gas temperatures drop significantly during heavy engine loads. This allows the turbocharger to spool faster and operate more efficiently without the backpressure generated by clogged honeycomb filters. Professional installers rely on this exact pipe to maximize flow on closed-course competition vehicles. Removing the factory emissions equipment prevents the engine from entering forced regeneration cycles. You can browse the complete CUMMINS lineup to find the correct pipe length and flange style for your specific wheelbase.

• Specification: Mandrel-bent 4-inch aluminized steel tubing for maximum exhaust velocity.
• Limitation: Requires a capable tuning device to rewrite the factory engine control module and prevent diagnostic trouble codes.

2. TruckTok 6.7L Cummins EGR Cooler Delete Kit - Complete intake carbon prevention

Factory exhaust gas recirculation systems route hot, soot-laden exhaust back into the intake manifold. Over time, this creates thick carbon deposits that choke airflow and degrade engine performance. The TruckTok EGR cooler delete kit physically removes the OEM EGR valve and cooler assemblies (replacing factory components like OEM part 68002433AC), sealing the ports with precision-machined billet aluminum block-off plates. This modification ensures only clean, dense air enters the intake manifold. By eliminating the factory cooler, operators also remove the risk of internal coolant leaks that commonly lead to blown head gaskets on high-mileage engines. This kit provides a permanent fix for intake soot buildup and coolant consumption issues on competition rigs.

• Specification: Includes high-temperature silicone coolant hoses and billet aluminum block-off plates.
• Limitation: The installation process requires draining the primary cooling system and bleeding air from the coolant lines upon completion.

3. TruckTok 6.7L Cummins CCV Reroute Kit - Crankcase pressure normalization

The factory closed crankcase ventilation system routes blow-by gases directly into the turbocharger compressor housing. This coats the turbo impeller blades, intercooler boots, and intake piping with a film of oil. The TruckTok CCV reroute kit eliminates this closed loop. It vents crankcase pressure directly to the atmosphere or a dedicated catch can. Keeping oil vapor out of the intake tract prevents boot blow-offs under high boost conditions and keeps the intercooler core functioning at peak thermal efficiency. For high-horsepower builds, maintaining a dry intake system is a mandatory step for long-term turbo reliability.

• Specification: Features a high-flow billet vent adapter and oil-resistant routing hose.
• Limitation: Venting to the atmosphere can produce a visible vapor and mild oil smell near the vehicle under heavy load.

4. TruckTok 6.7L Cummins SOTF Switch and Tuner Bundle - Multiple power level management

Hardware modifications require software calibration to function correctly. The TruckTok tuner bundle allows operators to flash the engine control module with custom mapping designed specifically for deleted trucks. Paired with a Shift-On-The-Fly (SOTF) switch, this system gives drivers the ability to change power levels instantly while driving. The tuning disables the factory emissions sensors, preventing limp mode and clearing dashboard warning lights. Adjusting injection timing and fuel pressure maps yields significant horsepower gains and sharper throttle response. Finding the right electronic support is just as critical as the hard parts, making these Cummins Kits a requirement for any serious off-road build.

• Specification: Delivers up to five selectable power tunes ranging from a heavy tow file to a maximum output race file.
• Limitation: Flashing the ECM requires an uninterrupted battery voltage supply; a battery charger must be connected during the initial download.

Important Compliance Notice

All DPF delete kits, EGR delete kits, CCV reroute systems, and tuning products sold by TruckTok are strictly for off-road and closed-course competition use only. These aftermarket components are not legal for use on public roads, streets, or highways. Installing these parts on a registered street vehicle violates federal and state emissions regulations.

Frequently Asked Questions

What is a DPF delete kit?

A DPF delete kit is a section of straight exhaust piping designed to replace the factory diesel particulate filter. It eliminates exhaust restrictions, lowers exhaust gas temperatures, and prevents the engine from entering active regeneration cycles during competition use.

Does an EGR delete require tuning?

Yes. Removing the factory EGR valve and cooler will cause the engine control module to trigger diagnostic trouble codes. Custom tuning is required to disable the EGR logic and keep the engine running smoothly without entering limp mode.

Why install a CCV reroute on a 6.7L Cummins?

A CCV reroute prevents oil vapor from entering the turbocharger and intercooler. This keeps the intake tract dry, prevents intercooler boots from slipping off under high boost, and maintains optimal thermal efficiency for the engine.

Are these performance parts legal for street use?

No. All emissions removal components, including DPF pipes and EGR block-off plates, are strictly for off-road and closed-course competition use only. They are not legal for use on public highways or street-registered vehicles.

What tools are needed for an EGR cooler removal?

You will need a standard metric socket set, a torque wrench, coolant drain pans, and pliers for hose clamps. The process involves unbolting the factory cooler flange and installing the new billet block-off plates.

Will removing the DPF lower exhaust gas temperatures?

Yes. The factory particulate filter creates massive exhaust backpressure. Replacing it with a straight pipe allows hot exhaust gases to exit the system rapidly, resulting in significantly lower temperatures under heavy engine loads.

How does a cold air intake benefit a deleted Cummins?

A cold air intake supplies a higher volume of dense, oxygen-rich air to the turbocharger. When combined with an unrestricted exhaust and custom tuning, it maximizes combustion efficiency and total horsepower output.

Can I run a delete pipe with the stock muffler?

Yes. Many delete pipes are designed to bolt directly to the factory tailpipe and muffler section. This allows you to remove the restrictive emissions filters while maintaining a relatively quiet exhaust note on your competition truck.

What happens if I do not tune after a delete?

Operating a deleted truck without the proper custom tune will cause the dashboard to light up with error codes. The truck will eventually enter a derated limp mode, severely limiting vehicle speed and engine power.

Do these kits fit cab-and-chassis models?

Fitment depends on the specific part number. Cab-and-chassis trucks often have different exhaust routing and wheelbase lengths than standard pickup models. Always verify your specific truck configuration before ordering exhaust components.
