Here in germany every race track has maximum db soundlevel! Last year I saw an Audi RS6 MTM that wasn't allowed driving on the hockenheimring. Thats why have a valve system!
With opened valve I have about 128db, thats enough

This is such a good thread but with minimal results. For a dollar to download the app and to get the reading at 5k rpm we could really create some good info

I'm running an AA rear with Challenge x pipe. No db meter, but it's pretty loud. I've set off car alarms, my wife can hear me coming home from quite a ways off and I'm just cruising, not accelerating hard.

The cold start is very loud. I've got an ESS tune but decided to leave it in just because I like the sound. I doubt the neighbors appreciate it much.

I think its louder with the AA X pipe, or at least seems so at times. Still loving it, though. You enjoying your akra?
