Eisenmann Performance Exhaust for BMW F8x M3/M4
The Eisenmann Performance Exhaust is a great upgrade to the tone of the BMW M3 F80. It comes with flaps that you can control the tone with the M1 or M2 button on the steering wheel via BMW's factory switching set up. You can also purchase this with different tip types and also mid pipes and downpipe if you desire. This setup in the video is just the rear muffler. It shows the different tone when you switch the flaps.

Dinan Free Flow Stainless Performance Exhaust installed on our Demo M235i F22. This is what it sounds like at idle and under a free rev. We have the BMW MPerformance Exhaust video on our channel as well to give you a comparison of the sound of the different Exhausts. Here is what Dinan say about their Exhaust, Dinan® engineers designed the F22 BMW M235i Exhaust to improve Exhaust flow by reducing back pressure, resulting in increased power output and a great sporty sound that is civilized when you want it to be, and pleasantly aggressive under hard acceleration. Dinan also incorporates a Helmholtz chamber design that reduces resonance or “drone” at low RPM. The system is built to exacting specifications to ensure perfect fit using the factory hangers. It is made from 100% 16 gauge 304 stainless steel and will resist corrosion for years to come. The design features twin 89mm ceramic black Exhaust tips for a tasteful, high-performance look. Maximum performance gains are 6 horsepower and 5 ft-lbs of torque. The Exhaust adds 3 point towards a Dinan® badge. Benefits of the Dinan® Free Flow Exhaust: + Includes mounting hardware + Helmholtz chamber to reduce drone + Enjoyably louder, sportier Sound + 100% 304 stainless steel construction + Twin 89mm laser engraved ceramic black Exhaust tips + 6 HP @ 6600 RPM, 5 FT-LB This Exhaust is available from Southern BM in Melbourne, Australia.
