Klarius has added 33 new emission control components, including a new aftermarket catalytic converter and several more options for the Mercedes C-Class. The 1993 launched C-Class provided an entry-level version of the luxurious S-Class, popular enough to entre its fifth generation 30 years later. The fourth generation (W205) was launched in 2014 at the North American International Auto Show with bold new styling, four different body types and a new, lighter design that used aluminium and high strength throughout the body. On the market until 2021, the fourth generation C-Class also had an update in 2019, which altered parts including the exhaust components.
