Glad you're happy with your purchase.
As far as the db reading... what method was this done at? The way we measure db's here is by regulation which is by using the SAE1169 method. This method is done at a 45 degree angle to the exhaust tip and 20" back. The test is done at 4500 rpm on EVO's. We have a "tool" that we made for doing this so its accurate on each system.
For those looking for a sound clip.... here are some clips a customer of ours made and posted on the Evo X forums.
