Back box to fit 3inch Jap speed system?

Hi, just bought a hawkeye WRX that's got a 3 inch japspeed system fitted. Even thought it comes with a restrictive bung to quiet it down I don't fancy ruining the airflow so wondered if anyone could recommend a different, quieter back box that might fit? Worse case scenario I'll ask Hayward and Scott to fab up something custom.
