In business for 23 years, this shop specializes in high-performance exhaust systems and custom built catalytic converters. Louie Cai took over eight years ago with over 20 years experience under his belt. He understands what makes cars work...and makes them not work, even making distinctions on the effects location may have on your car. If you live in Pacifica or Sunset, California where foggy weather conditions may accererate rust errosion, he'll zero in on different than if you've from some place further inland. The shop shares its real estate with Tony and Bob Independent, just next door.
