Sounds like complete crap, more like a fart can equipped civic.
They're still working on the mufflers, but I don't understand why anyone on this board would think this sounds even remotely decent, or would even think about comparing this to the current gen M3.
I guess they'll have to pipe more sound into the cabin, hey maybe by then they'll attach speakers to the mufflers to fake outside exhaust sound too!
