I noticed you have an Injen Cold Air Intake, do you think it might be rattling against the fender perhaps?

Which exhaust do you have? It could possibly be the thin metal heat shield underneath the car rattling against the exhaust.

You may be right about the exhaust. Shifting that low in the gear range will make your engine stutter a bit, and the midpipe or axleback may be coming inot contact with the heat shielding under the car. Get under the car and see if there are any spots where it looks close enough to hit and see if the area looks fresh from rubbing (not covered in dirt, etc)

no need to remove the heatshield, its there for a reason lol taking it away may not be the best decision.

When you get the chance to get underneath the car check all the connection points and see if a bolt is rubbing against the shield.

Bend the shield (it's aluminum or tin or something) and get a rubber piece or something to cover the bolt.

You can also just hit the shield with a hammer to "finesse" it into the proper shape. Its just a heat shield. Its easier to change its shape then the shape of your exhaust.
