300td4x4 Posted March 11, 2005 Share Posted March 11, 2005 Has anyone tried dual exhaust on a ej22 or any other subaru flat four for that matter? I would think this would improve performance. Obviously running the two exhaust pipes out the back would present issues. Link to comment Share on other sites More sharing options...
