Bought a new MPE muffler & MPPK from dealer and installed. The change in sound and response is very noticeable.

But there is a slight issue, after driving the car for an extended period of time and parking the car, the muffler will start a loud water drop noise. I uploaded a video on youtube see above.

The sound starts after the car is parked for like 5 sec, can last about 5 minutes.

The stock muffler doesn't make this sound, just wanted to check if this is normal or if should I ask the part department for a warranty replacement.

Sounds something flapping or floating around in there... I'd take it back to them and get it resolved that way via the warranty aspect.

Heated metal makes noises during expansion/contraction especially as it cools, but that seems excessive.

If the dealer or Indy performed the install, I'd take it back to them to recheck the fittings.

That’s significantly excessive, my MPE is pretty much silent after driving. It will make an expansion noise every once in awhile, but maybe 5% of that tone

Appreciate your input, will talk to dealer and parts and figure out a solution.

Curious what they say. I've had my installed for over a year and it semi does that. Always thought it was just expansion etc. I've heard it on other unrelated cars as well.
