Has anybody had a problem with a High Pitch Exhaust Whistle on a 3.9 2009
G6?

Ya I got that problem after getting my exhaust done...

You have 2 flex bellows on the pipes just after the cats. One or both have a small home in them. The are larger than the exhaust pipes and have stainless steel mesh around them.

The flex bellows allows your engine to torque back and forth preventing over stress of the exhaust system.
