Exhaust was too short, customer service eventually just quit responding after sending picture after picture of it being too short. The exhaust rubs on the transmission hanger bracket so I had to remove and cut that down. I would not buy this kit unless you want to spend extra time modifying it.

It’s more responsive in the pedal.
Fitment wasn’t the greatest could improve a lot

Tuner depot was very helpful I thought I screwed up on the tune part and flashing the ecm but there customer service told me I didn’t mess it up and helped me through it but one thing for sure is nothing to do with tuner depot but no one every tells you on a first time doing one of these trucks the amount of hours it takes it took me almost 30 hours which if I had the right tools and confidence I could of probably cut it down to about 20 but kit works great it’s got awesome power now and I’ll be doing the down pipe very soon to I highly recommend just buying it and getting it over with because the truck is still very quiet almost like it’s a notch above stock
GM Duramax L5P All-In-One DPF/DEF/EGR Delete Kit (2017-2025)
Just got them installed on my truck yesterday and cannot believe the increase in performance! Can’t wait to take it on a road trip already see more power increase and fuel mileage. Unbelievable would do it again tomorrow!
Love the sound of the straight exhaust especially on the Dirtymax they just sound badass without a muffler
I purchased the efi live sotf tunes along with Dpf delete kit, dpf was good quality, tuner worked with me and not only sent my autocal loaded with a sotf tune but also sent me a few single tunes to use until I installed the switch, the only negative was that 130hp was the max power tune single or switch on the fly, but over all I was pretty happy and service was very good throughout.
As described and shipped quickly.
Worked like a champ
Takes some time but help from support was appreciated
Needs better instructions for install but it was quality parts.
Not sure I like the hanger options but it sounds good and was simple to install.

6.6L Duramax L5P 5 Inch Downpipe-Back Exhaust System | 2017–2026
Easy install and like how it works.
Quality parts.
Delete kit was as it should be, only thing I’d say is the hardware is cheap and should come with bolts that can withstand heat so if a person ever had to remove them they won’t break. Also they don’t volunteer install directions which are super nice to have if you’ve never done one of these. I had to ask several times for the delete, ez lynk, and cam buss plug directions.
The ordering process was easy, the parts came fast and the response from the team has been incredible!
