RS engine doesn't sound as happy

No it's not a big problem.
First around 2500-3500 RPM (usually when decelerating.. sometimes when accelerating at certain speeds) i hear a loud buzzing sound that persists as long as i remain in that rpm range. it's quite loud actually. I can't tell if its directly engine related or if it's just perhaps some sort of shield vibrating sympathetically with that particular frequency since i've only noticed it at those RPMs. Have any of you ever noticed heard anything like that before?
The next sound is when I start climbing into the higher RPMs. Under acceleration I get some "tap tap" sounds coming from the engine intermittently and very faint. This occurs only sometimes... I can't pinpoint a specific scenario. It's happened on cold days, on warm days, while the engine was cold, while the engine was hot. I noticed it quite a long time ago and figured I'd just wait to hear it some more before I had to pay some mechanic.
Again the car runs fine. Starts up easy, idles easy, accelerates fine (for an RS), maintains speed fine, doesn't leak/drink oil, doesn't throw any CELs. The engine is stock as well with a a bit over 35k on the odo. The only thing under that hood that didn't come with the car is cable hooked up to the battery that I had when the 10" subs were still in the car. Those have been long since removed since they were too much bass even for me but the inline fuse is still resting on the window-washer fluid tank. I doubt that could be making the noise.
Anyways it's not an urgent problem. Maybe I'm just being overly paranoid. I just figured I'd run it by you guys to see if anyone has seen this sort of thing before.
