anywase just found this while surfing the net........does anyone has this on their car?.............i am thinkin about getting one of these instead of a $600 catback exhaust........i would probably weld this onto a test pipe.........the cool part is that in a flick of a button you can just run an open cat with a loud eggresive tone.......then another flick and back to the stock sound.........

My friend has it on his Trans Am and he has no complaints.
