Has anyone heard a knocking sound from the rear of their car after a speed run? It goes away after about 5 mins, but I want to know what it is.

most likely a popping from your exhaust. The stock system seems to get a little louder with heat. You should hear mine all the time.

It's the exhaust. Mine never did it until I put a magnaflow on it though. I've heard of stock systems doing it as well.

But it shouldn't take 5 minutes for it to stop. More like 2 seconds.

No, it does it during movement. It sounds like it's either the center rear or the right rear & it sounds more like thick plastic, almost like a playing card in a bicycle spoke.

You might wanna take to your dealer soon then. That's a new one to me.

Went to the dealer to find out what noise was, warped rotors in the rear. Thank God it was under warranty.

My stock exhaust pops all the time. People always compliment me on my sweet sounding exhaust. I tell them it's stock and they tend to doubt me. Kinda funny, I could only imagine a 3 inch exhaust, lol...

Yeah my exhaust pops too when I downshift & let up off of the clutch, I like the way it sounds.
