HKS Legal Exhaust System for 1991 Honda Civic

The Legal Exhaust by HKS is designed to free up the horsepower locked up in your Honda Civic's restrictive stock exhaust without increasing the noise levels too much. Using properly sized exhaust piping to give solid power gains throughout the RPM band and give the car a sporty but tame exhaust note under hard throttle. The Legal Exhaust is perfect for a daily driven car with minor bolt-ons.
