This 6.7 Cummins delete kit is built for 2007.5-2009 Ram 2500HD and 3500HD trucks equipped with the 6.7L Cummins. Designed for off-road and competition use, it removes the factory DPF and EGR systems while pairing vehicle-specific hard parts with matched tuning to eliminate common emissions-related failure points. The result is improved drivability, reduced exhaust restriction, and more consistent engine performance under load.

Delete Kit Includes
H&S Mini Maxx Tuner - Recalibrates the ECM to properly disable DPF and EGR functions, preventing check engine lights, derate conditions, and regeneration events after emissions removal.
4 inch Stainless Steel DPF Delete Pipe - Mandrel-bent 304 stainless construction reduces exhaust backpressure compared to the factory DPF assembly and improves overall exhaust flow.
Complete EGR Delete Kit - Eliminates the EGR valve and cooler to prevent soot buildup in the intake and reduce under-hood heat.
Performance Benefits
Improved Throttle Response - Reduced exhaust restriction and corrected fueling logic provide quicker pedal response and smoother power delivery.
Lower Engine Temperatures - Removing EGR flow helps reduce intake air and coolant temperatures, especially during towing or sustained load.
Increased Reliability - Fewer emissions components mean fewer common failure points over the long term.
Installation Notes
Professional installation is recommended. The truck must be tuned with the included Mini Maxx and verified free of diagnostic trouble codes before removing any emissions components. Standard hand tools are required, along with exhaust removal experience and access to the EGR cooler area.
Frequently Asked Questions
Is this a complete delete kit for a 2008 6.7 Cummins?
Yes. This kit includes the Mini Maxx tuner, 4 inch DPF delete pipe, and full EGR valve and cooler delete components for 2007.5-2009 Ram 2500HD and 3500HD trucks.
Can the truck be driven without installing the tuner first?
No. The ECM must be properly tuned before any DPF or EGR components are removed to avoid fault codes, limp mode or ECM damage.
What performance changes should I realistically expect?
Trucks typically see improved throttle response, smoother power delivery, and noticeable fuel economy gains once regeneration cycles are eliminated. Results vary by tune level and driving conditions.
Are all required parts included?
All major components needed for a full DPF and EGR delete are included. Optional upgrades such as cold air intakes, grid heater deletes or gauges are sold separately.
Is this kit legal for street use?
No. This product is intended for off-road and competition use only and is not legal for use on public roads.
Please note: The vehicle must be tuned without codes prior to any emissions system removal or modifications. Failure to follow instructions may cause damage to the ECM or void warranty coverage. This product is intended for off road use only.

Customer Reviews
Overall rating: 4.7 / 5 from 530 reviews.
I had another Tuner, Edge Evolution CS2, but the Minimaxx V1 works sooo much better! I have 2009 F350 6.4 Diesel. My truck runs PERFECT now and it has much MORE POWER! Love it!
The screen shows alot of details including engine code eliminates the need for a separate code reader. The on the fly tuning provides high horsepower within seconds if needed as well as higher fuel economy to going from 10-14mpg to 16-20mpg. The only downside to this whole kit is the mounting of the tuner itself. There's a windscreen suction cup that come with it but I wish they gave an option for a more sleek design like the one I had to buy though a 3rd party.
Purchased the system for my 2017 F350, mainly because a buddy said I would get better fuel mileage! While that is the furthest from the truth, I relish in the increased power and loud exhaust to scare the slow people who don’t know what a speed limit is. I purchased 36.5 tires for my truck and liked that the Mini Max V2 was able to calibrate for the larger tires and lower tire pressure requirements. Over all, quite pleased.
I am not a certified mechanic and the Mini Maxx was simple to install and very easy to tune and delete my 2009 Dodge 3500 6.7 Cummins Diesel. I have increased my performance on horsepower and mileage on both the performance setting and the tow setting. I am very impressed with this product and recommend it as well.
Probably was the Best Decision I’ve made! Let me tell you , This mini Maxx did things for my truck that thousands and thousands of dollars can’t do! I highly recommend this unit for any GMC Duramax owners especially to get ride of all the check engine issues related to the emissions system. Worked perfectly for me .
Still playing with it. Don't like there is no manual. Have to go screen by screen. When first installed I thought something was wrong because where the power levels are shown it said No Power. I thought it was the tuner or my truck. It ended up being one of the power levels. All in all easy to install and placed my unit down by my right knee at the little pocket there. Still easy to access and not visible from the outside.It did clear up all my problems so far. Waiting to pull my trailer so see the difference.
We need a replacement for the one that we have had for years. We contacted the manufacturer and they were out of the unit and not able to let us know when they would replenish stock. We searched online and found your company - placed the order and got exactly what we needed. So nice to have the unit attached to the windshield again instead of laying on the dash.
User manual could explain more about the “defueling” function, how and why it does what it does. Personally I prefer a physical paper manual that I can keep handy, otherwise it works fine.
