Bought my FRS with 17k miles on it back in December. I noticed this metallic-type buzzing right away where the torque dip starts to end (4-4.5 rpm). My car was recently tuned about a month ago by a friend, and the buzzing is still there.

When I was in for service last week (oil change), I explain it to them and had them take a look. They want me to bring my car in tomorrow so they can remove the TRD exhaust and install a stock one, to see if that makes it go away (not my idea obviously, thats what the manager/tech/whoever recommended they do)

I'll update here tomorrow when they tell me what's going on.

Also, should I worried about them spotting the tune somehow? I'm fairly new cars, mechanically.

any update on your exhaust?
