Worth a view (and listen), if you've never seen this segment.  The Z's straight six, done up like this, sounds like half a Ferrari V12.  Great sound.

I'm usually not a fan of flared fenders on these cars, because they usually look too 'Hot Wheels'.  This is the only Z I've seen with fender flares that add, rather than detract, from the car's looks.

 

Yes I saw the episode. The SOUND that you refer is accentated because of the lack of an interior. The sound resonates more through the vehicle in addition to more vibration. Nice car still not a fan of flares, they make the car look TOO Hot Wheels............ish
