BMW 4 Series models: New sound in a double pack

Hemmingen, March 27, 2022 - The 'Eisenmann Exhaust Systems' brand from S&R Eisenmann GmbH is launching a new exhaust system for each of the current BMW 4 Series models - (G22/23) 430i and (G22/G23) M440i. For the 430i, the exhaust back pressure has been reduced by five percent. With the M440i, the stationary noise values ​​are 95 dB (A) / 3,750 min1.

In contrast to the series, the rear muffler for the M440i model has an additional, electrically controllable exhaust flap. Tube diameters of 85 millimeters (430i) and 2 x 70 millimeters (M440i) also ensure better flow and a sonorous sound "made in Germany".

The sports rear silencers for the current BMW 430i and M440i each have an EC operating permit and are therefore approved for the road. Eisenmann also offers a sound tube for export and the racetrack.

And as with all sports exhaust systems from Eisenmann, the same applies to the current 4-series BMW: With both models, the owners can choose between different tip designs: chrome or real gold alloy (inner tip) or black anodized aluminum or aluminum and carbon (outer tip) are available. In addition, the versions differ in a straight section in the "Signature 'e'" version and a sloping section in the "Le Mans" version with an outer diameter of 90 millimeters.
