When i take off, just normally but especially from a launch, i hear this sound from under my car that sounds like a couple of pings, like when you shut down a car and it's been hot. Sounds like maybe the exhaust? I have no clue but i've been hearing it for a while. Any thoughts? Thanks!

could be a spark plug arching? coming from top end or bottom?

It's not coming from the engine at all actually. The sound is like a warm engine ping though. It sounds like its coming right from under the seats.

Maybe theres a zip tie on you DS? Could be alot of things, heat sheild rattle, sway bar bushings, exhaust banging the floor etc....good luck tracking it down

Check your 02 sensors, they may be loose and rattling. I had a similar issue.

Ya it really sounds like something on the exhaust. I might look for a broken hanger and check the heat shields again, but i've had a tough time tracking this down. Thanks for the help guys!
