No fix. I have the same thing after replacing the resonator and both secondary cats with a x-pipe. It's simply the higher RPM's of a stationary vehicle. Once the RPMs drop, as you say, it goes away. And just so you know, if it is making that sound, it's more times than not a cold start. All depends on how warm the engine is and how long it takes to drop to idle range.
