I was thinking the heatshield. No it has no mods whatsoever. I don't really feel like messing with the car myself when the dealer can check it. At the dealership her RSX goes to they treat us very well. She needs her tires rotated and oil changed within a week or so. I plan on going so I can address the problem personally and speak with the service manager. Thanks guys, I hope its nothing serious and it doesn't sound to be...
Peace.
