So I just started noticing a noise when I let me clutch out quickly with the rpms higher than normal. Like a quick pull out. Its almost like a squeak but not really. Is this a throwout bearing issue or a common mini thing? Id just like to know to see if i could get it replaced under warranty before it runs out. Any help is greatly appriciated!

 

oopps..Forgot to mention, Car is an 04 Cooper S. Mods are intake, exhaust and tensioner stopper. 58k miles and stock clutch as far as I know.
