Hey, I know this is a really late reply, almost a month, but thanks for all the input. I know that I most ashuridly will get longtubes, a mid-pipe, and catback, but a for brands, I don't really know. Things like this require research, and it takes time, which is all I have seeing as how I don't even own a Mustang, YET. So, I am thinking BBK LTs, BBK H-Pipe, and some brand of Catback. I know that I want chamberd mufflers, like GNN60 said, and as for dumps, I am not for sure. I know Flomasters are VERY popular, but I don't want to sound like everyone else. So, maybe a Magnaflow. I have no idea. All I know is, that there are a thousand different catbacks out there, and choosing one to go w/ LT and H-pipe ca be very tough. If I go BBK LTs and H, what should I get Catback wise to get that metalic tinny sound???
