Noise. Video. MSF diagnosis game?
 

Hi guys. Mods are listed below and are current.
Here's a tiny sound clip of the sound my car makes. To delve a little deeper, it doesn't happen in fourth, fifth, or sixth gear. It doesn't happen exclusively while the tires are spinning, though on a strong third gear pull without any "perceived" wheelspin, it'll happen.
First and second gear though, always.
Car pulls strong, but seems to be a bit low on MAF g's. Stratified mostly attributed it to high elevation (2700ft) and high temps (tuned in 100+ degrees) for the MAF reading. The sound hasn't been properly diagnosed. Intake tract has been clamped down tight multiple times, still does it. Where else should I look?

The noise I'm talking about is the maraca sound. Or maybe taking some sand in a tin can and shaking the shit out of it.

Logs would be nice. Got any?

Ask and you shall receive.

My intake started making all kinds of weird noises when turned up boost. It would make a bunch of weird whining sounds mixed with a light flutter. After I changed intakes... Noise went away.

I will listen on my desktop more closely tomorrow. In the meantime, fuck it. You have a warranty.

I came from the Subaru world, and dealers would scan the ECU and see how many times the car has had the ecu "flashed", and that was basis for a warranty claim denial. Any idea if this happens with us?

Secondly, anyone else have an idea what it might be? If I can head it off with a simple fix instead of getting the run around from the awful Mazda dealership here, I'd rather do that myself.

It looks like you are running a test pipe. If you are, does it have a forward brace utilizing the stock exhaust hangers? The reason I ask is that I was running one of those and it made a similar sound. After much hassling and looking at everything it turned out to be an occasional interference-contact with the exhaust hangers on the car frame from a poorly manufactured -weld job on my Corksport Race Pipe. I cut the brace off the pipe and sound went away. Just a thought.

It would help if you posted a log from when it happens, vs the 4th gear log you've posted in which you state in the OP it will never happen in 4, 5 or 6.

My apologies. Here's a third gear one.

It's been a while since I was under the car and installing it. The test pipe had no hangers on it, and honestly I can't recall if I pulled the stock one out of any hangers. The new test pipe had to be re-tightened because of a rushed install and I could hear some clangs when the RPMs got to low in reverse or first gear.

I'll get back under there and tighten everything up and see if there's enough movement for it to be the exhaust on the frame or the heat shielding under the car. Thanks

Looks normal to me. Check your air filter.
