Tanabe concept G. No drone. Great quality sound. Quiet wile cruising, opens up under throttle and gives a great note in the upper revs. Its about the best all around system for the car that keeps noise levels respectable but no annoying drone is the main thing. Looks great too. Its often overlooked for some reason. I've been sporting one since it came out about 8-9 years ago. Always get compliments on it.

second choice would definitely go with a Tanabe Medalion

Tanabe Medallion Touring and HKS Dual are both excellent sounding. The HKS won't lose much weight, if any. Both offer a mild bump in volume.

Sound clips without a sound level/noise meter are pretty useless.

If you don't care much about the weight savings or the aftermarket look, the UK exhaust mod is a good option also.

The original is far from quiet, but it's definitely drone free. I love mine

Mugen or Tanabe Concept G would best suit your requirements. There's a quiet dual exhaust from Amuse as well. I believe it's the Euro model. Look into that, if you're willing to spend that much $... fantastic brand though. Would love an R1 Titan for mine

The only way to know is to hear the exhaust on a car set up like yours. With S2000s rare where I was (and currently am) the only way for me to tell was to buy the "not much louder than OEM" exhaust and fit it to the car. This was, initially, the Invidia Q300. Guys recommending this must be deaf. Horrible. Droned. But looked fairly good. Off the car in a couple of weeks. Next try was the Tanabe Medalion Touring. Still on the car after two years. Wonderful exhaust.

But don't take my word -- or anyone elses. Make the effort to hear these exhausts from inside the car at road speeds. Or be prepared to spend the time, effort, and money experimenting on your own car.

Measured peak sound level for my Medalion Touring setup is 95dBA on an OSHA calibrated noise meter. Q300 was over 105dBA -- ear plugs required.
