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.

I have the same problem, but I don't have the factory flex pipes. I have the Thermal R&D 3" catback. Checked the exhaust for rattle and nothing. Thinking it might be the body panels underneath. But it's been too hot to check now. Will keep an eye on this post to see any other experiences.

Most likely the flex pipe.

This is the problem I have. I also have a 3" Thermal exhaust and the noise was present with stock exhaust/flex pipes and also with the Thermal. I did a quick check of the trim and nothing seems obviously loose. It usually starts to rattle at like 40-45mph+ and definitely sounds plasticy
