scraping caused strange noise..

[SubliminalSi]

I was leaving a parking lot today and the middle of my car scraped as i was pulling out. It didnt sound to bad, but as i was coming to a stop..a odd growl or rumble came for like 2 seconds and stopped..then when i got home i heard the samething. I looked under the car and didnt really see anything wrong. Any ideas? BTW i have HKS exuast

I would guess you jarred the exhaust and either caused a small leak, or it's rubbing. When the A/C cycles on it loads the motor and cause a vibration. I have the same problem with my piece of shit midpipe; it rattles when the A/C cycles on.
