The Phat quads are a touch quieter, but it sounds like you're more after the STi quads, which still has a lot of the OEM internals to keep it nice and quiet. Otherwise if you can spare the money, a set of K2 Gear quad tips will be the ultimate. Perfect for those wanting quiet during idle and normal cruising, but a nice note during hard acceleration. Plus it looks awesome!

Expensive though! But definitely worth every penny. You'll find it difficult to find any aftermarket mufflers which can achieve near stock sound levels.
