||The Eisenmann Race Performance exhaust for W219 (CLS), submodel CLS550 [2007-], 4x90mm Round tips, with FREE shipping - special order - see notes to follow... KO Performance is one of the largest US distributors of Eisenmann performance exhausts, and we have been extremely happy with their products since we began distributing them in 2001. Our customers have been more than satisfied as well. Here's what Brian L. had to say about the Eisenmann Race exhaust he installed from KO on his CLK 430 "I just wanted to say the exhaust sounds amazing on my clk430, at idle it has only a hint of volume over stock but when you put your foot in it heads begin to turn and the grin begins to form, I noticed almost no droning, a crisp and unique sound that urges me to drive the car more often. I would definately do business with you again. Thx for everything... Sincerely Brian L." - notes: This is exhaust is special order from Germany, and typically takes between 4-6 weeks to arrive in the USA before shipping to our customers.
