real muscle cars have iron blocks bigger than 400 cubic inches. we don't own a real muscle car. we have an aluminum smallblock motor that is well known to rasp...severely with louder exhaust kits. one of the only cures to this is to run cats. cats belong on an LS1 f-body. they sound like **** without cats. ALL catbacks rasp at some rpm without cats, at least that i've heard.
