M&M Exhaust GmbH produce our entire “Brombacher” exhaust line, basically anything that begins with part # BES or RES. M&M's modus operandi, racing. They are Germany's premier racing manufacturer and have exhaust systems running in these series: Porsche Super Cup, Carrera Cup Deutschland, ADAC GT Masters, IMSA/WEC, VLN, FIA GT and Rallye Meistershaft. They also produce the current and past RSR, Cup R and Super Cup exhausts for the boys in Weissach. Not one of our competitors can make that same claim.

THE HEADERS are the longest tube headers that M&M make for the 911. The length directly equates to torque in the mid-range. When you look closely at the pictures of the headers you will see that the primary tubing is segmented and welded. It is not a single tube that is “mandrel bent” in many places. The mandrel bending process stresses and thins the material by bending it around corners. Thinner walls are the weakest point and under high heat and vibration will be the first area to crack. Our primary tubing is segmented and welded under pressure with the use of forming gas. Forming gas pressurizes the area being welded to create a smooth inner surface. This means that material walls in the bend are consistent and strong, ensuring reliability. This process produces extremely durable headers with superior strength that ensures higher gas velocity and less exhaust gas restriction.

The header piping used incorporates a motorsports style merge collector. The collector smooths out exhaust flow and turbulence created from the 3 primary pipes merging into one. This dramatically reduces power robbing turbulence and increases the volume of gas and gas velocity which translates into superior low end and mid-range torque.

THE MUFFLER is vastly different than the common baffle plated mufflers stuffed with packing material that are common in the aftermarket. Ours are uniquely made with double perforated sound absorption tubes based on the Halbgegenstromprinzip (half counter current principle). The acoustic silencer absorption tubes are made in a trapezoidal pattern and are perforated with varying diameters, which isolate and dampen the unwanted frequencies that create drone. These perforated tubes present much less flow restriction than baffle plates at higher gas velocities, and consequently translates into larger horsepower and torque gains throughout the entire rev range. The resulting sound exhibited is a sonorous, firing-order dominated flat 6 Porsche sound, which also gurgles and crackles off throttle.

THE EXHAUST TIP is a single round 2.5” (63 mm) design that appears stock, until you start the car.

*PLEASE NOTE: This is a Bespoke Exhaust System. It can be custom designed, and the tubing diameters can be adjusted for your car's individual performance. Please provide your FVD Parts Specialist with detailed information on your current Horsepower and Torque, if you are running larger displacement, upgraded camshafts, larger diameter intake, etc. Pricing and part numbers may vary according to your individual needs. This exhaust kit is intended for Race use and is not legal for sale or use on California pollution-controlled motor vehicles.
