My Supra make pops even after done driving it and it’s just sitting there parked. Is this normal? Does this happen to other Supra’s? The pops are coming from under the body near the exhausts.

I could be wrong, but it sounds to me like it is just heat expansion and contraction on the exhaust and other warm parts. Normal after getting the car hot and then letting it sit to cool after. I guess you could check to see if the exhaust valve on the right exhaust outlet is being actuated or something, but that seems unlikely.

I have noticed, that this car sounds like old 90s cars after driving them. Like either some sort of condensation or something dripping onto underpanels or something.

How many miles does your car have? Mine makes the same exact noise too.

Mine does the same. 6k miles. Just metal cooling down.

Could be the exhaust valve actuator opening/closing.

If you see the exhaust valve fixed then assume the resonator expanding contracting which is perfectly normal.

Good luck.

That's the sound it makes when you were using the car correctly during the previous drive. If you never got it up to temperature and/or drove it like a grandma... it would pop much less (and be utterly pointless). Mine's done it every one of the 350+ days I've driven it. ;)

... it will get a bit better after 10K miles or so (at least it did in my case) once all the metal in the exhaust and heat-shielding gets more "settled" - it will still do it some however.

Roll down your windows when you’re at a stop light, you’ll also hear the pinging there when idling :D

It's normal, mine did that up until like 4k miles last I remembered then suddenly stopped one day. I'm at 13k now haven't heard it since that 4k mileage mark

My A91 does it too. I’m going to figure out which exhaust component is expanding/contracting and get rid of it. Good excuse to get a new exhaust.
