Funny you mention mustang sound. I've never, ever heard a good sounding mustang. Ever. Not even a good sounding ford for that matter. Nine times out of ten when I cringe or think what a crappy sounding exhaust it's a ford. But, you know, go for what you want to. That being said, I'd delete the mufflers.
