I know that exhaust, it is loud. I actually think it exceeds 95db which is legal limit in many states, so it'd be nice to not have them call cops and get you on their radar. I'm actually one for thinking that we should be allowed our freedoms and most neighbors need to mind their own business, but if its way too freakin loud, and it's your daily driver... that's kinda rude. This is the main reason I went with the Cobb exhaust (its actually full tbe, but not much louder than cbe, just a bit deeper), its fairly quiet at idle but sounds great and rewards you with a great sound soon as the turbo punches. On top of that, I got in the habit of coasting slowly in neutral as I entered my street.
Hope this helps.
Oh by the way, if you did buy a new exhaust, the TurboXS should have good resale value. At least its not some loud ass eBay chinsy thing.
