Im going to buy an x-pipe and a cat-back system. Im looking at the bassani x-pipe, but Im debating on either the bassani cat-back or the flowmaster american thunder cat-back. Power gain is an issue, but so is a good sound, I really like the muscle car tone of the flows I have now, and Ive seen a vid of the bassani system with the x-pipes and it doesnt even match my single flowmaster muflers. Or mabey the vid quality is just crap. So any imput would be nice. Here is the link to the vid: http://www.sacramento-mustang.com/video/cc_bassaniexh.mpg
