Help choose exhaust for 2011 supercharged

[anteyv]

Hello, help us choose aftermarket exhaust, for 2011 RR supercharged full size. If you help out I will make video clip after its installed I promise
I'm looking for above average loudness. Anyone have FOX exhaust? How does Eisenmann sound, is it loud? video clips on youtube don't sound that loud..

Also, 5.0L would sound meaner?
