Key Benefits of Deleting EGR on LML Duramax:
✔ Improve Fuel Economy & Power
Removing the EGR system restores airflow efficiency and combustion, resulting in up to 20% improved fuel mileage and throttle response.
✔ Reduce Engine Temperature
Soot build-up in the EGR cooler and valves can trap heat. Deleting the system lowers EGTs and improves overall engine cooling.
✔ Avoid Expensive Repairs
Failed EGR valves and coolers can be extremely costly. This kit eliminates those components, saving you money over the long term.
⚠️ Important Notes:
This kit is intended for off-road/racing use only.
Will retain OEM intake and exhaust manifolds.
Professional installation is recommended. No instructions included.
Compatible with most EFI Live or EZ Lynk tuning solutions.
Frequently Asked Questions
Q: Will I need to tune my truck after installing this kit?
A: Yes. A delete tune is required to prevent check engine lights and to optimize performance. We recommend pairing with our LML-compatible tuners.
Q: Will this work with my 2015.5 model?
A: Yes, our kit is compatible with both early and late 2015 models. Please verify the engine code (LML 6.6L) before ordering.
Q: Does this affect my turbo system?
A: The up-pipe design improves turbo spool by reducing exhaust restrictions without modifying the turbo itself.

Great Product
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.

Missing tuner!
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

5” exhaust
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.
Slick kit and the best bang for the buck out there
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!
