making the GTP loud

i have a 1998 GTP and i want the exhaust to be loud. i understand its a 6cylinder but it is a big 6 and it is supercharged so it must have some good sound. someone replied to another guys post saying that catbacks arent worth the money. would i get good sound off trubo mufflers or upgraded mufflers or do i have to get the whole cat-back system. id rather not spend the 800 bucks on a catback system. also does anyone have a exhaust on there GTP does it sound ricey or does it sound deep and rumbly. if you do tell me the brand and where you got it plus the price. i want my car LOOOOUUUDDDDDD

You can not have your car sound like a rice with a v-6 engine. Magnaflow or borla would be the way to go.
