I seem to have a problem underneath my car. When i start and drive for like 1/4 mile it sounds like metal is sheering off or rubbing against each other. It just started a bit ago and I recently put on a Greddy Evo exhaust on it single. Does anyone know what this could be? Imma' be taking it in tomorrow I just thought I might get some input.
