Code:

// Is compression requested?
if ($CFG->item('compress_output') === TRUE) {
    if (extension_loaded('zlib')) {
        if (isset($_SERVER['HTTP_ACCEPT_ENCODING']) AND strpos($_SERVER['HTTP_ACCEPT_ENCODING'], 'gzip') !== FALSE) {
            ob_start('ob_gzhandler');
        }
    }
}

This is where CI is starting it's compression, which involves header changes - probably a good place for your to start modifying yours as well.
