Anyone have any idea about an exhaust that sounds like a Maserati Ghibli?

That's very specific but it'll be interesting if there is something out there.

I doubt you can find anything to make it sound like that, in my opinion these engines take all the goods parts of a VQ. If you want a good sounding exhaust for not too much money look at Remark's axle back exhaust. If you want something more pricey with a better sound I would suggest ark grip's cat back exhaust. If you really want to get loud Invidia sells a cat deleted mid pipe that can be paired with their axle-back system.
