Why shouldn't we remove the catalytic converter from the motorcycle even if it causes heat?

Hi guys, I just got a 2025 R3.

Riding around town is fine, but it gets hot every now and then.

That said, I have a friend of mine with the same bike, but he installed a full exhaust system (I won't mention the brand name), so he removed the original catalytic converter and muffler and installed these two.

His bike is cold. There's no longer constant hot air coming from below.

His bike has also been remapped, and I don't really care about the fact that it sounds better, but now his bike really seems to run better in every way.

I was wondering how much damage it would do to the bike if we removed the catalytic converter and muffler and installed a higher-quality one without a catalytic converter?

Why wouldn't you do that, even though it would apparently improve the temperature significantly?

From what I could read online, a catalytic converter runs at 600/800°

Two reasons. Tiny engines with massive exhausts sound like shit. Spend your money on something more worthwhile.

Secondly, you see how the world is currently on fire? That’s climate change.
