I've watched this video from Petrolicious *so* many times now. That induction sound is intoxicating, something that I'd want to strive for if (sorry, when) I pick up an air-cooled 911. Does anyone know what is contributing to that intake noise? I've read that this car is running a hotter cam, fwiw.

Good audio recording.

May have a drilled airbox? Honestly, it doesn't sound that different from my car (open airbox, primary muffler bypass, cat delete)... but as Spyerx notes, petrolicious really did a good job capturing the sound.

The induction noise sounds pretty normal. It's all exhaust sound. He's not running the factory heat exchangers or any cup pipe g-pipe combo. Probably headers to a dual in dual out main exhaust.
