After looking around for awhile im really confused on what catback system to buy for 2002... i want to have a nice deep idle and overall sound. I guess im looking for the loudest catback system that is legal. so far i have looked at Magnaflows (original + magnapacks whats the difference), Borla (i dont like the tips they offer), and flowmasters. Any others that you recommend or can lead me in the right path? thanks!
