automotive market had endured the OPEC crisis, increases in gasoline prices generally, fuel economy pressures from consumers, and increased competition from efficient and reliable Japanese cars. Emissions regulations increasingly demanded engines spew a lower volume of toxic chemicals from their exhausts. By 1979, the U.S.
However, many people wanted exhaust sounds and the feeling of transmission gear changes. They make the IONIQ 5 N sound and feel oh-so like a gasoline-powered car. The Ioniq 5 N is an absolute blast to drive on a race track, equaling and bettering many gasoline-powered sports cars, but that isn’t what we are considering here.
A dual exhaust system can spice things up, adding an electric fuel pump helps prevent drivability issues with modern gasoline, and adding sound deadener can cut down on noise and heat intrusion for a more comfortable drive.
