One of the best aftermarket exhaust manufacturers in the world, the German company Eisenmann has long been regarded as a favorite by the BMW enthusiasts.
A lot of M3s, M5s and M6s had their "vocal cords" replaced with something from Eisenmann. Whether it was just a muffler, of a tip or even a whole exhaust, products from the German company have been fitted on BMWs ever since the 90's.
Being one of the oldest aftermarket exhaust manufactures, it was only natural that they released a complete system for the brand new F12/13 6 Series. Their exhausts are homologated and available for the following models: F13 Coupe and F12 Cabrio 640i, 650i and M6.
Prices vary from €1,695 for the 640i rear muffler to €3,153 for the M6 rear muffle. However, the mufflers and sound pipes come in 2 different diameters: 90mm or 120mm. If the first ones, the 90mm diameter mufflers, the installation can be done without any kind of modification to the rear bumper, the 120mm ones require slight alterations.
