5" Down Pipe-Back Full Exhaust Delete | GM/Chevy 6.6 Duramax 2017-2023

The boxes that the products came in were smashed

L5P Delete Kit with SOTF and full 5” exhaust.

I have deleted several diesels, I can say this has been the easiest experience I’ve had thus far. The exhaust fit great, downpipe fit great, this truck was a ‘17 and everything in the kit was great and worked perfectly except two things: 1. Kit needs 2 more 3/8” hose plugs and clamps for the coolant lines for the def injector. 2. The quick connect for the heater core hose needs an upgraded version, for example Dorman makes a billet aluminum quick connect for the heater core connection and they’re $25. I replaced both at the firewall when it’s drained of coolant and replacing the one anyways. You’ll never be stuck on the side of the road with a trail of coolant behind you. Other than those two minor items, the response time for emailed questions and phone calls are very quick. In fact they called me and asked a few questions and made sure everything was going well. I will buy from this company from now on! One stop delete shop literally. No more scouring the internet to get all the parts gathered up and then dealing with a “tuner” for the file. The tunes I got for the duramax are GDP. I have ran their SOTF tunes for 7 years and no issues. I’m sure they may use a coupe tune companies, I didn’t ask. They even included the can-bus plugs. I will say this, I looked at one of their competitors and they were cheaper by almost $1k, BUT, I seen where the items were coming from and when they couldn’t tell me where the tune files came from and customer service was on the opposite side of the earth I passed. The savings to me wasn’t worth their 20-30 day lead time they quoted, I had all my stuff from them within 5 business days. All in all I am very pleased with the service I got from The Diesel Dudes!

L5P 5 inch exhaust

Kind of expensive and is a very tight fit but sure does sound good though. Overall am very pleased with it.
