engine noise on cold start.
Hi, i notice that when my car starts on a cold start i get this noise for about a minute or 3. i opened the hood and figured out the noise was coming from this part. any idea what it is or what i'd need to do to fix it? its sort of a high pitched noise.

I believe it's an air pump that pumps air into the exhaust or something like that to help with emissions.
Mine makes the same noise and I've been told by other members that it's ok.

Generally when one installs a catless midpipe, they remove the airpump. Without a cat, the airpump serves no purpose. RacingBeat sells a $12 block off plate for the exhaust manifold for this process.
You CAN remove the pump entirely, however i'm not clear on which electrical connections you need to leave intact as to not trigger a CEL. Hopefully someone else can help you there. I'm SURE its been covered before elsewhere on this forum.
