Not sure what that is, looks like it could be custom but I've also seen a lot of Skylines and Supras with similarly huge exhausts. The backbox on that is massive, I'd imagine as far as "cannon" exhausts go it's probably quite quiet. It's a good look I think, but unless it was just an empty metal shell it wouldn't be loud enough for me, and I think a single speed bump would be the end of it, the end of the box looks like it would not be more than 2.5" from the ground in that photo!
