Whats up guys, just picked up my 07 Silverado Z71 LTZ couple weeks ago. Couldnt stand the quiet exhaust so I had a custom flowmaster 40 series with dual 4" tips put on the first day, and added my DiabloSport Intune a couple days later to get rid of the horrible drone when AFM kicked on. Looking forward to hanging around.
