Installation Notes
Installation can be done in about an hour using basic hand tools in your driveway or garage. Some cutting may be required for short-bed models, and some factory hardware may need to be reused.
⚠️ IMPORTANT: A DPF delete-capable tuner is required to prevent check engine lights and diagnostic trouble codes. This product is for off-road use only and is not legal for highway use in emission-controlled vehicles.
Q: Will this delete pipe fit my 2006 Dodge Ram 2500?
Yes, this pipe is designed to fit all 2004.5–2007 5.9L Cummins models, including the 2500 and 3500.
Q: What’s the difference between the 4” and 5” options?
The 4” pipe fits most OEM and aftermarket exhaust systems. The 5” offers slightly more airflow and is ideal for tuned or heavily modified trucks.
Q: Is this a complete delete kit?
No. This is a standalone DPF delete pipe. You’ll also need a tuner and an optional EGR delete for a complete delete.
Q: How much can I expect to increase my fuel mileage?
Most users report MPG increases from 13–14 to 18–20 MPG after DPF removal and proper tuning.
Q: Do I need a tuner to use this pipe?
Yes. A delete-capable tuner is mandatory to disable DPF-related sensors and prevent warning lights or limp mode.
Very good quality, fitment was great, shipping was fast. Best prices around. Would definitely recommend, and would buy again
2005 dodge ram 3500
Easy to put on and install sounds amazing and looks good
It was packaged very nicely, quality is top notch and installation was very easy. Had installed in about an hour. That was taking my time and removing the old exhaust. Would highly recommend!
Quality checks out good job guys not scamming much love
Let customers speak for us
I was a little scared it would make the truck sound like a soda can but it actually sounds deeper and way better so I can’t complain easy to install ( if you have the long bed you may need to cut back 4” off one of the middle pipes to get the hangers to line up very easy solution make sure you cut the side that doesn’t have a bell end)
be sure to update mini Maxx with the latest firmware 2.0.0.8 FIRST! I learned that lesson😟
I also on my 2019 ram ended up plugging OBD bypass into middle row fourth one up after doing that I got zero codes truck runs great !! customer service isn't a whole lot of help mini maxx responds to emails but not quickly.
The product is great. Does what it's designed to do.
The instructions? Not so much. Luckily, the Customer Service people do their best when emailed and walk you through the process start to finish. The only other thing I'd like to see are the basic beginning settings for setting up "defuel". Every engine is different (Ford/Chevy/Dodge) and finding this info through forums is terrible.
I currently have the DPF deleted, the EGR turned off, and the race pipe has a 27" stainless resonator added to keep it quiet. It rolls coal on "Extreme" and the increase in power on "Stock" is very apparent. I run it on "Stock" 100% of the time and gained over 2 mpg so far on the first tank.
2013 F350 Crew Cab Dually 50225 miles on odometer. No rust anywhere, pristine Cali truck. I guess the original owner couldn't afford to drive it. LOL
It was packaged very nicely, quality is top notch and installation was very easy. Had installed in about an hour. That was taking my time and removing the old exhaust. Would highly recommend!
The craftsmanship is superb and wish I could say the same for the OEM Plastic CCV box. The four security screws were challenging and used Irwin external extractors versus easy outs.
I received both the EGR and Downpipe delete kit quick but there is no Tuner! No tracking number for the tuner and says all my parts have been delivered! What the heck no one spent a grand on a straight pipe and EGR! However they did fix it promptly and I did receive the tuner! So I would say five stars
Honestly, the exhaust was much nicer than I expected fitment wise. It fit just as well if not better than exhaust systems I have installed in the past that were a few hundred more dollars. Shipping time was pretty good as well… received it the same week I ordered it. That’s about all I can speak on for now as I have only put about 100 miles on it.
Everything you need and nothing you don't. The parts install really impressively smoothly.
Could definitely use better / ANY instructions, especially since youtube vids on deleting trucks have been taken down lately.
It took a day of searching and watching vids here and there to find out it is extremely important to go in a certain order:
1: install the tuner first
2: install a "smog equipment has been removed" tune even though the truck still has the equipment at the moment.
3: remove the dpf and egr bits
Money well spent. Install was simple. Do not misunderstand simple with easy. Although it was easy for me. Install of the MINI MAXX V2 was a bit different. The video provided on the site was not how my installation went. In fact it was very different. With that, it did go as expected. The tuner does have some what of a learning curve, not very much info out there now with all the bureaucratic garbage we, in the US, have to contend with. It is out there, just TOUGH to glein. The removal of that gargantuan nightmare of an exhaust filter was not for the faint of heart. It is heavy, and the connectors on all those sensors can be challenging. It will be worth the struggle. The removal of the Extra Grace Required part was the hardest part for me. Having had my exhaust and turbo out 2 times, one of the bolt heads got damaged in the last re-install. That took a huge amount of patience and correctly applied downward force and a special tool. FYI THE PYROS DO NOT READ CORRECTLY ON 2011 F350 IT WILL ONLY READ 1193°!
Then the block off bypass parts, easy install. Looks great and does everything I expected. As a plumber I was able to use some expansion couplings and cut the water tubes and did not use the supplied hose. Then back on the ground to install the exhaust pipe. That was a challenge. The hanger bracket wasn't quite on par and was bent a bit. Nothing like a torch and a quality set of Pittsburgh 3/4" box end wrenches. Got that squared away, lined everything out and the slip joint went in nicely. I only used one of the 3 bolt flange bolts because I saved 2 of the pressed in studs. The down pipe connector flange was a special kind of hurrah. Perseverance, busted knuckle, and lots of upward pressure, accomplished that.! Overall I like the kit, don't like it doesn't come with instructions, but if you're buying this kit I'm betting you're already a mechanic anyway. HUGE THANKS TO SPETUNER.
One more thing, FedEx delivered my 1st kit to 2 wrong addresses, SPETUNER made it right and sent out a new kit for my. That is worthy of my review!
Perfect fitment, solid welds, good thickness piping and flanges. For about $200 can't beat it
