Hey guys whats up? Just bought my first truck and I only want to do a few things to it. Its a 2011 Silverado LT extended and I wanted to put some parts on it. The reason I started this thread is because my buddy just bought a 2010 Duramax 6.6 and he was told that if he bought exhaust it would void the warranty. I wanted to buy a K & N cai possibly the filter too, a chip, 2" leveling kit and force II flowmasters. Will this void my warranty at all? Thanks Guys.
