Aftermarket exhaust system manufacturer Eisenmann unveils their exhaust system for the new BMW 1 Series M Coupe. The Hemmingen-based company will start offering two stainless steel exhaust systems for the new entry-level M model.

Along with the street legal equipment, Eisenmann will also offer its customers a racetrack-tested exhaust system. The entire exhaust system is manufactured by hand and will help the in-line six-cylinder under the hood to not only develop more sound power, but thanks to a clear airway also even more horsepower: 10 extra ponies brings the total power to 350.

The sport exhaust system will make its debut at the 2011 Frankfurt Auto Show, but orders can be currently placed. The pre-silencer with EC-approval costs 535.50 euro, while the muffler, replaced with four tailpipes each measuring 83 millimeters, brings the cost up to 1,309 euro.
