Your very lucky living in the US.
Our police carry decibel meters with them and on Friday and sat night cruises they will write you a ticket if the exhaust is ‘loud’, and they will write you up for an inspection. The inspection is where the trouble starts as such, because I would be altering the original steering from OEM that’s an issue, changing a pump doesn’t interfere with the mechanical connection of the steering, another little one they do is make you turn a tight circle, if your inside wheel scrubs indicating you could be using a spool in your diff, they will write you up as an unroadworthy vehicle. Yes your lucky in the US
