2012 kx450f header

Hey. I'm new to 4 stroke 450s. I have a 2012kx450f, and I was changing the oil tonight and I fired it up to let it idle and noticed the header was glowing red. I only let it idle for. 2-3 minutes. Is this normal. Thanks for the help

Is it stock or aftermarket? The fmf powerbomb on our yfz450 does the same with no issues.

It's all stock

It is normal

I did the exact same thing and freaked out. Scoured online sources and turns out to be normal. I went to the titanium header and it's thinner than stock and that thing gets cherry red when it's dark No melting/warping or distorting.
