Arguably, the three most famous/popular "best" sounding exhausts are the ScoobySport, Stromung, and Prodrive. A smart move is to find someone in your local area with the exhaust component(s) you are interested in to hear it in person. Seek out locals via the NASIOC Chapters or NASIOC Regional Areas.

Which exhaust is the quietest? This question can be answered by listing hard data:

a. M2 Performance 94dB @ idle
b. GReddy Evolution 94dB @ idle
c. MRT Twin Tip: 96dB @ idle
d. Prodrive: 91dB @ idle
e. STi Muffler: 93dB @ idle

By using hard data, you remove human judgement and don't get stuck with a recommend "quiet exhaust" that in your opinion is now a loud and expensive nuisance. Keep in mind that these quiet exhausts only protect you from the chance encounter in areas with strict noise abatement laws. At wide open throttle (WOT) any aftermarket exhaust is considerably louder than OEM and even the quiet ones will not protect you from folly.

Which exhaust is the loudest? "Commonly known" loud exhausts are the TurboXS RFL, Worx Tuning, Helix, Blitz NUR Spec R, Kakimoto, and BPM Twister MKIII.
