Man I have the Hooker AERO Chamber its black and a direct bolt in for a LT1 car and DAMN it sounds mean behind a 6 speed. Deep, throaty, and not very resonancy (that a word?) but its not that pricey either and it's not a trendy Flow. so its different. Check their website they have it on a 85 Malibu and of all things its powered by a LT1/auto drivetrain. Trust me...sounds great.
