Still haven't been able to figure it out. Doesn't seem to be getting worse. A person on another forum suggested it might be a cracked flex plate or the torque converter starting to fail.

Exhaust is aftermarket from turbo back, it seems like it's coming from the front passenger side of car. This is the best video I could get on the way to work this morning. You can start to hear it about 1/3 of the way into the clip.

I have a 2006 Legacy gt that has developed a weird sound. When the car is under load around 2-3k it makes a metallic rattle, almost like a spitting sound, it's hard to describe. Can't hear it unless the windows are down and I'm driving next to a wall or other cars. All the heat shields are tight and I don't see anything making contact where it shouldn't. It doesn't make the sound when revved in park/neutral or when it's torque stalled. Car still seems to run and drive fine and makes plenty of boost. I get no feedback knock or fine learned knock at all. All fluids are pristine and at their proper levels. A used oil analysis was done 500 miles ago and came back perfect. I was leaning towards a cracked header or up pipe but would think it would struggle to make boost. I'm thinking about taking all the heat shields off for a more thorough inspection but the bolts are pretty seized up. Anyone have ideas or a direction to head in? I'll try to get a video up asap. Any input will be greatly appreciated this noise is driving me crazy
