Method 01

in config/routs.php

$route['404_override'] = 'Controller name';//this to avoid 404 Error

Method 02

in your controller check empty

$data['product'] = $this->Model_Name->get_product($id);

if(empty( $data['product']))
    {
        $this->empty_result();
    }
    else
    {
        //load relevent view
    }

In controller at top create function call empty_result()

public function empty_result()
{

    $this->load->view('template/header');
    $this->load->view('template/right_sidebar');
    $this->load->view('template/NothingFound',$data);//create a page to show empty or Nothing found
    $this->load->view('template/foot');
}

In Model

public function get_product($id)
{
    $query = $this->db->query("SELECT * FROM product WHERE id ='$id'");
    $result = $query->result_array();
    return $result;
}

In view (template/NothingFound.php)

create file call NothingFound.php

in that

<h1>No thing found title</h1>
<!--customize the view as you want. Add some images-->

EDIT 01

Method 03

Goto error/error_404.php

Edit the error message to display in your styles
