997 Valve Tronic Exhaust Leak

[997 C4S]

My 997 C4S had developed an exhaust leak or heat shield vibration that is very annoying during acceleration. Current mileage is 45,000. Anyone have this problem and care to share what you found before I tear into the exhaust system to find the leak. Makes the same sound when sport mode is turned off and accelerating.
If I tear into the exhaust system and find more than a gasket or loose heat shield, the plan is to upgrade to a Fabspeed exhaust and eliminate the Valve Tronic stock setup. Have already added the air intake and love it.

Thanks
