Trumpet player is most likely the collector ("header") to up-pipe connection. Its a fairly common location to get a leak.

If you are at all handy, drive the car up onto ramps (or the sidewalk), drop the engine lower cover, and with a flashlight and a mirror inspect the connection. I bet you will find a hot spot where the oem gasket is starting to fail. Im betting you need to drop your collector/header and replace that gasket. Most likely can reuse header to block gasket.

GS makes a extra thick gasket that I suggest using for this location.

YOU DO HAVE A TORQUE WRENCH RIGHT? Otherwise don't bother and just take it to a shop as you will only make it worse not better.
