Any ideas? You can hear the loud "whir" at startup. I was thinking alternator but I'm not sure, hoping one of you guys could have an idea.

 

Could that be a pressure leak. I cannot tell from the sound.

 

At first I thought I heard an exhaust leak but I'm guessing that's just an aftermarket exhaust, huh?

The whine does sound like an alternator bearing to me.

 

The noise hasn't returned.
Muffler delete but I think there is a small exhaust leak.

 

sounds like a lawn motor... at first i thought its the rattling of the exhuast manifold but then no doesn't sound like a rattle... i got noise problems at startup too so im going ot take a camera and show u guys in a bit
