Hey guys I'm actually new to ford and I like it the only thing is a rattle/knock sound coming from either my cat which making it sound like it comes from the motor or from the manifold. It's annoying and makes me not want to move at all. It's starts when I fire the engine and after warms up it only makes a noise if I stay under 2000 rpm or in 5th gear at a slow speed watch video I posted to somewhat see the problem and thank you for the help.
