I have a system similar to those, but not exact. The mounting system is different, but the mufflers look exactly the same, so I'm not sure if i have an older MAC or if it's a different brand but similar type.

I should mention that the chrome isn't that great. It pretty much matches the somewhat crappy Honda chrome, so I like it.
