What can I remove from my car to make it sound better and go quicker ? Is there a long-term drawback ? Audi, VW and Seat Engineers have designed my car with all aspects considered, it already goes quick, but unrestricting a measured airflow ? They design them with consideration to environmental, performance and style. Will this increae the co2 emissions ? will my children suffer beacuse I am increasing pollution ? Do I care ? post some piccy's.
