Hey Bro,
You are going through what I had to endure for sometime now, my end result is a CorkSport CBE. The thing is actually much "quieter" then the stock one. it does not drone like the stock one does, however it does get a bit loud if the car is in stop and go traffic with the windows down, but when theyre up it's all good, and once the exhaust temps drop from cruising you don't notice the exhaust at ALL! My wife noticed the difference RIGHT AWAY after the install, but she started to notice the "loudness" when the windows are down, so now I just drive with the windows up when she's in the car and no issues.
Corksport is your BEST bang for the DOLLAR, plus you pick up ponies and wont' break the bank and the quality is amazing!! but if you really want quiet you'll have to go with a GHL, but that's gonna set you back a good 700 bucks.
