It didn't drone before. Understand the people with 928s and drone problems don't put the racing cats on when they do the x-pipe thing.

Before starting all this work it was just a bit too loud for my taste. Like the hp gains and tone, just not the loudness.

Still have the stock muffler from before the Rear Muffler Bypass install. But it was way to quiet. It is also huge and heavy. Understand the 928 GT resonators are bigger than the GTS resonators. Maybe just need to find some GT resonators or a similar replacement. Would love to stumble on it sounding like my old 928GT!
