most noteable with stock exhaust and engine.

Anything with the Nissan VQ35DE, mainly the 350Z or the G35 Coupe

Either the Corvette, Shelby GT500, or Dodge Magnum.

New? Used? You can get 355's now for 50k.
Vettes are pretty tame sounding. They sound too incredible with a nice magnaflow to say they sound good stock. Id say my 350z sounds really good for under 50k, but the g35 coupe has an even better tone.
S2000's sound good for I4's.

There aren't many stock systems that sound good, anyhow.

Hey Speedy, howd ya hear the GT500 exhuast? I've heard of people who have good hearing that can hear things coming a mile away, but you can hear things coming a few months away! :alchi:

My vote goes to the BMW M3

C5 Vette.

Any used Cadillac with the 4.9 :cool2:

I've heard the Mustang Cobra's before and they sound great! The GT500 is basically a Cobra with the Shelby name and a few other extras.

Since the Ford Mustang GT was listed already... I'll say the LS2 powered GTO

SRT-8 Charger... or my LT1 Fleetwood with the Borla and CIA headers :thumbsup:

C5 Corvette With Borla Cat-Back on it.... sounded great. Super nice deep rumble at idle, and cruising around town... there were pressure baffles in it, so when you got on it, it opened up and started roaring like a beast.... outstanding.

A turbo FD RX-7... nothing like the sound of a rotary at 9 grand!
