As per my consideration you can call function of that service in your success responce and process your data in function and return it to back it.

return this.http.get(url, {headers: this.headers}).map(
      (response: Response) => {
        const data = response.json();
        return this.processData(data);
      }
    ).catch(
      (error: Response) => {
        return Observable.throw(error);
      }
    );
    
public processData(data : any){
  //process your data
  return data;//this is processed data
}
