I bought my 2011 LML Duramax back in June, 2012. When I picked it up, I was still a little skeptical. I had given up my LBZ for it and wasn't sure how it would work out for me. My LML was stock when I bought it and my dad had an identical LML of his own. I knew I needed to stick out. I started by switching out my stock exhaust with a MBRP 5 inch straight pipe fitted with a Diamond Eye down pipe. After that, I got under the hood and put in a S&B cold air intake.
I wanted to get a little more out of the LML, so I hooked up a H&S Mini Maxx tuner and an Alligator Performance LML Turbo Resonator. I also put in a 3" drivers side intercooler tube. I added a modest Ready Lift 2.5" leveling kit and added new tires and rims to boot. After I started on the exterior, I couldn't finish, so I replaced all my lights with Smoked Recon lights. I gave the windows a 15% tint and added carbon fiber Chevy Bow ties. With the addition of RoadArmor matching bumpers and an AirDog 165 fuel air separator system, my LML Duramax was finally the way I wanted to see it. I'm currently using my truck as a daily driver and use it to tow excavators and trailers for the family landscaping business. Im very happy with my LML, it runs strong and has continued to prove itself.
