want to upgrade the exhaust on my 98 gt, but there are too many choices! i'm a teenager on a budget. could i just add and X or H pipe and leave the factory mufflers?would it sound good? or do i have to do a complete catback system? please help with the best way to get louder with the least amount of money!
