Hey yall, not sure if this is the right place for this, but I figured I'd give it a shot.

When I accelerate from a stop, I hear what sounds like unmuffled engine noise that sounds like it's coming from near the front of the car. It's not a complete roar like the muffler fell off but it's way louder than I'm used to. After I hit 2nd gear (automatic) the noise essentially stops and it sounds normal again. The sound can't be reproduced in neutral. I inspected what I could and the exhaust line is rusty but doesn't appear to be broken. I also don't see any issues with mileage.

Anyone have any ideas?

And if this isn't the right place, can someone direct me to the right place?

Thanks for the response. It also doesn't make the noise unless I hit the gas if that helps. I guess I'll get it looked at given your tentative general prognosis.

Is it only ever on acceleration regardless of gear?

Edit: I’ve found what might be an interesting thread. V6, 2012 mentioned. Could be as simple as the heat shield. Have a look (with an adblocker):

Only when accelerating in 1st gear. Once I get past that, it stops. If I stay in 1st gear and pump the gas, it only happens when I pump the gas. It does not happen when I Rev in neutral or when stopped at a light

The thread mentions low rpm so it might be relevant.

Whoops why did my comment clone itself. Never mind.
