I have a 2011 stock 3.7 f150. With about 55k miles. If I'm in park or neutral and rev to around 2k Rpms as the rpms go back down I hear some rattle in the exhaust under the driver side. Anyone had this problem before? Haven't even had the truck a month yet.

Check your heat shields, exhaust connectors, and exhaust hangers to see if any of them are loose.

I got under it today looking for what it was. Sounds like it's comming from inside the resonator. a friend of mine told me it was normal but I don't remember it being there when I bought it. Thinking about just cutting it off and putting a straight piece of pipe.
