Kit showed in a timely manner and worked perfectly
I will start by saying the quality of the Equipment is great and your staff are amazing. The install was simple until I got to the down pipe, back side, near the exhaust. It wouldn't fit unless I removed the studded bolts on one side (I chose the bottom ones). That wasn't too difficult because I knew to spray ALL the bolts down with WD40 penetrating loosener before I started work. The instructions emailed to me didn't match what was sent and I am assuming they just needed to be updated. I went to YouTube and found 2 videos that helped me out. FYI you lose 1.5 gallons of antifreeze, make sure to place a catch bucket under your truck. Doing this prevented a big mess. You will need lots a patience, extensions, pry bar and PRE-SOAK the nuts and bolts. So far, the truck runs better and with a total delete now I went from 15 mpg's city to 17.5 mpg's. Hwy went from 18 mpg's to 21 mpg's. I also installed the SOTF and keep it at max HP. I recommend buying from DD and to get a more accurate DIY how to install, watch YouTube. I am amazed at what comes off and what little goes back on. Thanks for everything DD.
Ordered bundle with muffler. Anytime I had a question The Diesel Dudes answered promptly and got me the info I needed. They have all the instructions you need. GDP tune working great for me. I would note that if you have a 19-20 model that has had the y78 recall done and you have the cp3 pump now.....when you download tune from GDP, make sure it says 21-22 year model. The 19-20 labeled tune is for the cp4 pump. I verified this with GDP technicians. All it takes is an email to GDP and they will have the correct tune to you by the next day. Muffler installed is almost as quiet as factory but with a much deeper tone. Don't hesitate, do it.
The customer service is second to none! I love these guys. My kit and tuning software all arrived at nearly the same time. I couldn't have asked for a smoother experience.
The delete was delivered within a few days and installation and simple with the step by step video and written instructions. Should have done this sooner, it runs better than ever
Excellent product, I highly recommend. Great instructions on the installation. Excellent customer support!
High Quality and everything worked flawlessly. Great video instructions and written. Can't say enough good stuff about their product. A+++++
Overall great product and easy to install with the instructions. Everything fit perfect and works great.
I got the full delete kit and everything seems to be top quality, I'm slowly working on my truck but at the same time installing a new air intake from airbox to the high ram. I can't wait until it's done then I will share more with you on the performance.
If you follow the instructional videos they send on loading the tune file to the tuner and loading the tune to the truck it's very simple and easy. I had a little scare at first because when I tried loading the tune on the truck I got an error saying no data read. It turned out it was just because I did not turn the key to the on position. The video tells you to do this, but there is never a message on the tuner itself telling you to do so. I did not install the switch because I just want to run the stock power tune which is the default. I installed the delete pipes before the tuner was delivered (impatience) so my truck was already throwing codes before tuning. As soon as the tune finished installing, bam, the codes were clear. The truck runs great. and the tune is very clean. There is no black smoke unless you really floor it. I just installed it two days ago so it's too soon to give actual gas mileage improvement numbers, but I can tell you for sure that it has increased based on the readings I'm seeing.
I received the kit promptly and extensive instructions were emailed. The kit went together perfectly and all parts were of great quality. I originally did not order a muffler with my kit but decided after a few days that I should have. I contacted sales via email and within 24 hours they had a muffler quote sent to me and to my surprise with free shipping. I am 200% satisfied.
I have just over 200,000 miles on my 2018 Ford. I wish I did this the day my factory warranty expired. Very pleased
The truck acts like it doesn’t know if it wants to change gear or stay in the gear it’s in.submitted a form for tec support and only get the same email back to fill out a support form other than that it’s a delete kit but the tune sucks
All the way through the order process up to the delivery of the 3 shipments the customer service is very helpful and response in a timely manner. And the technical support team is very helpful and knowledgeable about answering any questions you might have during the process of deleting your truck.
I originally only gave the kit four stars because I was missing a clamp but I was just informed that they have already shipped me another one! Five stars for a great kit and great customer service.
Received the sweatshirt in a timely manner and packaged well. It’s made of thick, high quality material, and seems like it will hold up well.
The EFI live and 5” exhaust with no muffler sounds amazing !!! This thing is now a completely different truck period. I can’t say how happy I am with the product and customer service from these diesel dudes 🔥🔥🔥
I'm writing this view because this kit only has two currently and I may be able to clear up some people's questions/doubts.
I'm only giving this four stars because you need three clamps and they only sent me two. You need the third clamp to clamp the end of the last section to what's left of your tailpipe after making the cut behind the DPF. The clamps they supply are very good. Unfortunately, I had to go to my local auto parts store and buy a U-Bolt clamp for that last connection. The U-Bolt clamp is not nearly as good as the clamps they provided and I have reached out to see if they can send me another one but have not heard back yet.
I bought the this kit along with the EFI Live tuner for my 2015.5 GMC Sierra. I was on the fence about whether to get the muffler or not because I was afraid it would be too loud without one but I also didn't want it to be as quiet as stock. I decided to go with no muffler and I'm glad I did because it's actually not that loud at all. Even on startup in the morning it's not loud enough to where you would need to worry about bothering your neighbors; its a low rumble. There's no drone, and with the windows up I don't even need to have the radio up any louder than I usually would. With that being said, you can definitely hear the turbo whistle and blow off which is what I was looking for! Do not go with the muffler unless you want the truck to be as quiet as it was stock.
The hardest part was removing the original system. If your truck is not lifted I recommend driving the front end up on ramps. You do need to make one cut on the original exhaust, in my case about 11 inches back from the DPF. If you want to get the cat out without dropping the transmission crossmember then you will need to make a second cut just before the cat. Once the old stuff was out, installing the new system was smooth sailing other than having to go buy a third clamp. I had no issues with the tune, but I will do a separate review for that.
Easy install. Fast shipping. Would highly recommend
Shipping was quick , the install went very smooth . Customer service was great .
