Intake and Exhaust Mic'd Up Cruise (Video)

Made this video today. Might redo it because I zoomed in the camera a bit too much a little bit into the video. But I mic'd up my intake and exhaust separately and went for a short cruise. The recorder I used I believe also had a limiter set on it not to pass -3db, so after 4500rpm the audio gets a little screwy. I can plug headphones into my recorder to monitor audio in realtime, to see if it's clipping or hitting the limiter, but I didn't think to do that at the time.

at 10:55 is where I go to redline

It's eventuri intake, MPE valves open, fabspeed sportcat, and bootmod3 stg2.

I don't mind it, I think it's unique. But, the way the car is, you can't hear any of that while driving anyway. It's only because the mics were literally right next to the intake that it sounds so loud. These yellow boxes are where the mics were.

Gotcha. If you could do another recording of how it sounds in the driver seat that would be awesome. everything else about that intake makes me want one

Intake on turbo just does nothing for me. MPE sounds good though.

Same, I've wanted one since I first saw it at Essen a couple of years ago but all the video's I watched have the whistle and wooshing and I'm pretty sure I couldn't live with that and I know my wife won't live with that so we'd end up taking her Q5 everywhere. I don't know if guys who have recorded the intake have put the mic right next to the air filter but I'd appreciate hearing what sounds like from inside the car.
