My 1998 3000GT SL had an awesome oem exhaust. Sounded throaty but not loud at all. My 300ZX's exhaust is so quiet you can't hear it at all,not even standing behind it.
I love my current car. The 6.1 simply is always powerful sounding outside but whisper quiet inside all the time.
Nice thrum of power at idle with a bit of a bark if your foot is in it, but it doesn't make every cop for miles wake up and look around....

Long tube headers, offroad x pipe, cat back - Bassani the whole way.
Best. Sounding. Car. Ever. Between the supercharger whine and the exhaust note it was intoxicating. Had people flag me down more than a few times to ask about it. The ladies loved it, too.
The engine of my Fit is so quiet, I used to try to start it sometimes when it was already started and just idling -- resulting in that nasty grinding sound from the starter. I've learned to check to see if it's started by checking the tach.
1993 Skyline GTS-T. RB25, Full Race header, ARC exhaust, t3/t4 turbo. Hi revving and strung out turbo straight 6.
Honorable mention: 93 Twin Turbo RX7. Peter Ferall Supercars exhaust, So smooth. Still had the factory airpump on it so it sounded terrible/awesome at the same time.
I've never had a hot-rod, but I recall my new 1993 Dodge Dakota with the 3.7L Magnum having a really cool rumble to it.
I also installed an inexpensive rear muffler delete on my new 2014 Subaru XV Crosstrek for a short period of time. The unequal runner length on the new FB series engine's exhaust manifold gives them a nice raspy burble when you get on them (w/out rear muffler), but this little bit of noise transferred too much vibration and harshness into the cabin on my XV. I slapped the rear muffler back on. Literally takes 5min.

WOW! ...and i thought i was Japanese big-time with my Greddy EVO VIII and bubble eye WRX between 2004 and 2007.
