So i'm trying to sell my stang but i've noticed an issue with the exhaust. The left pipe seems to rattle ONLY when im in drive, never in neutral or park..only in drive WHEN im like stopped at a light or something with the break fully applied. If its somethin possibly a simply fix ill do it but i think im gonna take it in to where i got my exhaust done at to have em look at it.

Any ideas?



...i had my mother sit with it in drive with the break applied and of course...nothing happened
