Just picked up a 2013 Silverado 1500 Crew Cab LTZ with under 9,000 miles, traded in my '05 Sierra SLT Extended Cab with 158k. Opted for non-Z71 as it appeared to me that you could not get 20's with a Z-71 package, and I decided I prefer the 20's... don't do a lot of off-roading except getting through the snow of Iowa winters. I'm sure this is nothing too exciting to most of you, it is pretty much stock but it had a spray-in liner and tonneau, which I would've added right away if I had bought one without. It's exciting to me though, I've never owned a vehicle with 4 digits on the odometer! For now my only plans are: K&N intake, possibly exhaust, and probably Diablosport with Diablewtune, or possibly a different tuner... I'll do more research myself when the time comes, but for exhaust I'm looking for something that is subdued/mellow under normal conditions, and only loud when I get on it, if anyone has any recommendations.
