Loud Whurring Sound at Start Up
 

Yes, ladies and gentlemen, my air pump went poof!

I find it ironic that it decided to kill itself after I put in a mid pipe thereby negating the reason it's even there. Thankfully mazda covered it under warranty.

So if you go to start up your car one day, and it sounds like ball bearings in a hair dryer, your pump is kaput!

what is this "warrannty" you speak of?
glad you got it fixed though.

warranty is that thing your dealership gives you when you're nice to them. I also had my 30k service done, so that (removed number because it's just ridiculously large) probably helped grease the wheels.
