just a tip... you can quote multiple posts at once by pressing the button just to the right of the quote button to toggle select it (little green spot turns red), and when you are done selecting which posts to quote, you click "quote" on the last one you toggled select

 

according to a review I read it has a deep base sound at idle but at about 4000 rpm it gets quite loud. after VTEC kicks in apparently the engine evens out the noise but you can still hear the exhaust. (thats for the Greddy evo2) Have you thought about magnaflow?

 

is a video i made about my greddy typre rs BOV, and the car has the Greddy Spectrum Elite SE exhaust. and your can tell the exhaust is pretty Quite.....

That exhaust looks really nice. OP, just about anything with a standard oval shaped canister is going to be relatively quiet for aftermarket exhaust. The round canister "fart cans" or "coffee cans" exhaust is what you want to stay away from.
