Is there a Legal decible rating for exhaust?

i think he’s been lucky or that cops dont care. his car is loud as fuck. Mine is pretty loud and is my own personal limit in sound, i wouldnt go any louder.

headers and off road y will be super loud lol.

and if the cops are just riding your ass, i’d stop somewhere and let them pass. if they stop with you, i’d ask them whats up.
