Yeah, should pass no problem, it's only under load or revving that this engine get loud, steady rpm should be fine.

Look at OP, his DB rating is without mufflers. (although not following mic placement guidelines) gives us some kind of idea.

Stock Muffler Delete, replaced with custom bent aluminum tubes to tips.
~75-80db idle in car while warm
~80-85db in car while in 6th gear on highway (around 70-80mph)
~96db out of car under heavy acceleration
~104db inside car under heavy acceleration in 4k-5k rpm range (drone zone)
