After years of wanting a SS Silverado, yesterday I finally took the plunge and bought one. It has AWD and a few performance mods. It has a tune on it but I'm planning on going Nelson of course. It has shorty headers (planning on LT's) and is straight 3" to the tips. No cats or mufflers. It needs mufflers very bad. Way too loud. All in all its a good place to start and I can't wait to blow all of my money on it. I'll get some pics up tonight or tomorrow. -Josh
