High pitched ticking noise coming from the engine

Hey guys, after doing some spirited driving here in Nashville this afternoon, I noticed a slight ticking noise coming from the engine/rear of the car, its not specific to any side I checked.

I have a pretty loud exhaust so I'm not sure if its ticking when I'm driving, but I noticed it when I got out of the car and it was idling. It ticks like the tip of a screwdriver hitting can, or heavy rain hitting a metal roof, so its high pitched and tangy. Additionally, theres no set pattern to this ticking, it could be ticking consistently once every 1-3 seconds then stop for 30-45 seconds, then go on again, then stop for 20 sec, and start again...

I did notice that the ticking got more frequent when I had the car in sport mode (since the idle revs are a little higher).

I've see some other forums mentioning "ticking noises" but those were mostly the injectors making that noise and this is definitely not that.

Anyway, here's a link to the youtube video I recorded after I noticed the ticking issue, (would recommend turning volume all the way up).

It could be a few things:
  • Muffler/Exhaust system
  • I need to replace coil packs and spark plugs soon, could be that
  • Serpentine belt

Is this something serious? Should I be worried?

I haven't found a forum thread that has this same issue, so if you've experienced this, or might know what the problem is, any insight is super appreciated.

Thanks for this, just ordered 2 in case 1 more backs out at some point like @ICNU has had.
@DomeDepot Welcome to Porsche ownership! I'm in Nashville too, maybe see you at one of the local Musik Stadt meetings someday. I think you may have found the culprit, makes me want to go out and check my header bolts too. Mine (987) also has some ticking sometimes but it hasn't exploded on me in 3 years. I also have the oil analysis done and if I had something bad like bore scoring I think they'd catch it. My oil has a clean bill of health every time.
Not sure if links can go through here but look up on YouTube Rennvision's video Noisy Lifters. He goes into several sources of potential Porsche engine noises.
Aye nice to see another local in this forum, yea I'm fairly new to the city/car scene here, moved in 22' to west Nash, close to Charlotte pike and I40. Didn't even know there was a PCA zone here but now that I know I'll definitely be attending some of these events.

Good idea on the oil analysis. I might have to get that done next time I get my oil changed (which is in a few months here). Got any lab recommendations I should go with?

It's a good local club here, and there's about enough activities each month to please anyone.

I've been using Blackstone Labs for the analysis but another one to check out is Speediagnostix
