After driving my less than 9 thousand mile old 2k6 Xterra. After I shut the engine off, the catalytic converter &/or exhaust pipe pings &/or pops.

Anyone else have this happen to them? What is it?

Is there aTSB on the catalitic converters?

Thanks a bunch in advance

the first time i heard that pinging noise after i have just brought it home from the dealer, i nearly dove under the X to see what it was and finally came to the conclusion that it had something to do with heat expansion on the metal after driving it, and it was just a cooling point to where metal shrinks back to normal size. so, yes it is normal for the X i guess.

Will it ever stop doing it? I love my Xterra & it pinging makes me think theres a problem
Yupp - it will stop doing it every time you drive after about 10 mins! lol.

You could of course go to an aftermarket exhaust system, which may be better or worse, I just consider this normal tho.
