Rattle Noise Underneath

[jwalkerftw]

Have any of you guys experienced a rattling noise when decelerating at low speeds? I’ve heard that the stock mid pipes make the rattle noise after some time on a higher mileage ST is that true? I’m 21’ ST just reached 50k miles.

Flex pipe. It should rattle a bit if you tap it with a wrench or something.
