All-aluminum 6.0L Gen IV LS2 V8 engine accompaniied by 400 hp and 400 lb-ft torque, hood scoops, dual exhaust, and you can hear from miles away. A slight exaggeration but whatever. I haven't put in a system yet but i have a stock 10 speaker blaupunkt system that doesnt hit too badly. The seats are ridiculously comfortable and i love every thing about it.
