I'm stuck on which catback I want for my 16'. I haven't heard any in person, I may have to go to some local meets and out to Royal purple raceway to hear some. I've only found a few that I really like so far. I love how the Borla Touring catback sounds, but its $1,300, and I think it may be to tame? Has a good tone, but it uses a mid muffler set up which I think quiets it down a bit. I also like the Ford Racing (made by Borla) touring axleback. It has a little rasp to it from the youtube videos i've heard. I'm trying to stick with something that has little to no drone, and has a good hollow tone to it, thats not too overly loud. I think I should stick with a h-pipe, but not sure which mufflers. I do want to keep the stock cats. I've had several x-pipes on previous mustangs, and I don't think I want to go that route on this one. I'm not much of a fan of the "tinny"/"raspy" sound anymore. I've listened to all of the big brands, magnaflow, borla, and corsa and other than the Borla touring i'm not really enthused about the other brands. Anyone have any suggestions?
