I have a 94 Accord EX Automatic 4cyl sedan , first off I'm not sure what the exact gas mileage is, I haven't tested it nor do i know what it was advertised for originally, so if anyone knows that would be great, but right now it seems like I am getting really crappy gas mileage, I have an intake and a axel back exhaust installed. Does anyone know what might be causing this bad gas mileage issue? Thanks, Ian
