Weird sound when full throttling.

[sp3GT]

I've been noticing that when I full throttle my car it makes a flickering sound, kinda like a leaf flickering. It doesn't matter what gear I'm in it still makes it. It's more noticeable to me when i'm travelling at highway speeds though.
Could it be something stuck in airbox?


Thanks,

are you guys 5spd manual or auto?

There were some guys that experienced a fluttering sound and it was the shifter cable metal shielding hitting the exhaust manifold heat shield.

Also, one guy took out the heat shield and noticed that a bolt holding the bracket down was 'missing'. only one was holding it down from the factory.

This seems pretty serious, I'm 5spd as well.
