Hey everyone! I'm new here but have been going through a ton of information on here before getting my first Duramax. I just recently sold a heavily built Silverado 1500 that I had for 5 years. I ended up needing something that I could tow with legally and not over exceed the weight limit. It will also be my daily for my commutes to grad school and work. I was planning on getting a 2017 L5P Denali HD but decided it would be more fun to go with a truck just out of warranty and save some coin.
So April 29th 2017 I drove from Florida to Mississippi to pick up a 2012 GMC 2500HD Denali I found. I feel like I got a pretty good deal on it. It had around 123k miles on it. It look like it hadn't towed anything in its life and was clean. It has all the options I wanted and some to spare. It has the rear entertainment package in the headrests. It also doesn't have a sun roof which gives some extra headroom.
First thing I added were Weathertech molded front and rear mats. Then I added 15% tint on the 4 side windows and over the rear glass. Later on I'm going to get 50% over the entire windshield.
Through my research I'm going to complete the most important/helpful mods first. I'm about to drop a good amount and get the Fleece CP3 conversion, Airdog 4G 165, FloPro 4" or 5" exhaust(I'm leaning more towards the 5"), BAS EGR kit with intake pipe, and all tuned by EFI Live from Hardway Performance in Mary Esther FL. Hardway Performance will also be doing all of the installation on everything listed. I'm also planning on getting an Edge CTS monitor to switch tunes and monitor the important gauges.
Here are some pics:
Also any advice on what to look into next are appreciated.
And any advice on whether to go with the 5" or 4" exhaust and muffle or no muffler.
