Car mods, police and old guys.
From my experience, I'm 54, you will not have any issues from the police if your car is safe, not too loud, not too low and your not being a dick.
For when you get pulled over, and you eventually will, ensure your intake is boxed/covered, if you have a catch can it is plumbed back, BOV is plumbed back, and if your tune is super rich you clean the unburnt fuel and carbon off your rear bar.
Nothing says pull me over more than the rear bar covered in unburnt fuel and carbon.
The police are more interested is stupid young guys who blatantly flaunt the laws and cruise around creating a massive heat signature.
Enjoy
