So i've got an 07 yz450f, i put a Megabomb header on it...when i start the bike with the choke on and let it warm up the pipe gets super hot and starts glowing bright red, right off the block to the actual megabomb expansion. Once it's warm it goes back to it's natural color of metal. Is this something i should worry about? Is it just cuz the pipe isn't broken in yet? I never noticed this with the stock pipe.
