No kidding I couldn't believe how good the I6 sounds. I already unplugged the vacuum actuator so now it uses both tail pipes all of the time, made it a little louder and more pronounced and idle and low throttle.

I'm hoping the downpipes don't change the sound, just make it a touch louder. If not I'll do the cheap exhaust mod, which involves cutting open the muffler and making some changes on the inside of it.
