I loved the Magnaflow on my E60 M5.
On my E90, it droned like crazy, like so badly it drowned out my wife in the passenger seat at 2000 rpm. And then it got quiet over 5000rpm.
I hated it. It was the worst drone of any exhaust setup that I've owned. Not even any of the other exhausts with an aftermarket X pipe droned that badly.
