I was curious cuz my dads being a dick about it
Is he just worried about you burning a valve, or is he saying it's too loud?
If it's too loud, his house, his rules. Get a muffler or a pipe.
If you don't have a muffler or some kind of exhaust system on there, I'd get one ASAP anyway. It will run better, it will run cooler, and your exhaust valve will thank you.
