I have a 04 neon, sounds like a bunch of bubble bees! When u start it, the steering wheel vibrates, and mirrors. When u go that's when the bumble bees take flight! Lol everything vibrates but gets a little less loud about 45 mph.
The tranny shifts fine, engine sounds good, steering wheel doesn't pull... Just sounds like the exhaust on the frame type noise.
Also speedometer doesn't work & check engine light because of it... And suggestions?? Also at top left appears there's newer engine mount

Sounds like your right side engine mount might be bad. A good place to start might be to search this forum for "torque strut alignment procedure".
