I have a 2005 Silverado 1500 with the 5.3L V8. I want to get a cat-back exhaust system for it. I have an idea on what I would like it to sound like. I want the truck to be LOUD, but i want a deep pitched rumble when i get on it. I just need to pick the muffler out i want for the truck, im having the pipes made up. Any suggestions??
