db level of Cobb exhaust

Does anyone have the db level info for the Cobb exhaust. Just the CBE. I think the stock exhaust is 88 db. I am looking for an exhaust that is not to loud, but definitely not quiet. I like the Borla XR1, Blitz Nur Spec Touring and the Cobb. I read that the borla tapers to 2.5 inches though and that the Blitz has a tendancy to burn bumpers. I really dont want a grape fruit shooter either.

I think there is one from Borla called the Hush Power or something like that. its a single muffler dual tip and 3" and will adapt to the stock downpipe or to an aftermarket one.

Hmm I just bought my 02 and from what I can tell it has an aftermarket muffler, but all the other piping seems stock. The tip is massively big and its a little crooked and imho just makes the whole car look bad. If the borla is that quiet I might be getting the Borla.

I'm not sure the exact decibal level but Cobb states:

"The COBB Exhaust systems conform to the SAE dictated 95-devibel exhaust noise level limit enforced by California, as well as other states in the US"

I have the catted TBE and depending on my mood its either too loud (when I'm cranky in the morning in stop and go traffic on the way to work) or not loud enough (weekends with the windows down driving on windy back roads). Bottom line is its deep and loud enough that everyone knows they're something nasty lurking under your hood scoop. I would definitely recommend.

at idle maybe. It's more than that at higher RPMs. I rarely find myself thinking "man, this is too quiet" and I even have a cat in my downpipe

my invidia g200 actually isnt too loud at all, its got a huge cannister and a resonator to muffle it down. If i ever get a ticket for it being too loud im going straight for a borla hush, i grown to like it

well, i am buying a Cobb CBE, used that is 8 months old, with about 10k through it for 300 bucks. I think this is a deal, i have pics to post of the exhaust and its in good shape. Is it a good deal? the same guy also has a Invidia divorced waste gate DP for sale and it is catted. However, i heard that there is no need for a divorced waste gate on my 07. Is this true? or should i get both for a really good deal?
