2 spiral mufflers and the FTE resonator ... you basically don't notice the exhaust next to the turbo whistle and general 12V noises.
the extra thick lizard skin on the valve covers, oil pan, and tappet cover i think made a really big difference worth the effort too. you'll never make that engine quiet, but the harshness is gone.
