My Hey everyone, my name is Mac. I live in north MO, I'm a Army vet, spent little over 4 years as an infantryman. I now work on my farm raising Angus cattle. I use my 2007 GMC 2500HD with the 6.0 as my work horse, office, and everything else. I have a flatbed on it and soon I will hopefully have dual exhaust, cold air intake, and a tune. I look forward to getting good advice on what works best.
