I don’t hear a growl, but your exhaust sounds very loud.(Like your muffler is shot, you have a hole, or a gasket blew out.) As Selahdoor suggested maybe your exhaust deteriorated somewhere on your trip and the growl is just a louder exhaust. (Drone or hum of a louder or new note.) Gasket, hole, muffler, pipe, or?xc_hide_links_from_guests_guests_error_hide_media
Video link to hear the sound I’ve got.
I’m not getting any noise specific to the air intake and the exhaust feels/sounds pretty even. No puffs. Have not compression tested yet but will this weekend.
Thanks Bart for the guidance, exactly what I needed
It would make sense as you say it happens under acceleration when the exhaust is generally the loudest. (Now louder.)
Perhaps you check your exhaust for cracks, holes, and leaks. If you find a hole try to patch it with some exhaust fiber heat wrap tape. When it dries go for a ride and see if that stops the growl. If the muffler is rusted out inside, that is the growl, the heat wrap is not going to quiet things up. But if the muffler or exhaust has a hole in the side of it perhaps it will.
If your exhaust is quieter then you also might be able to better hear what the growl is. Maybe just install a new muffler if the rest of the system is ship shape.
