M Exhaust GmbH produce our entire “Brombacher” exhaust line, basically anything that begins with part # BES or RES. 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, ALMS / LMS, VLN, FIA GT, IMSA and Rallye Meistershaft. They also produce the current and past RSR, Cup R and Super Cup exhausts for Weissach. Not one of our competitors can make that same claim.

THE HEADERS ARE the longest tubing headers that M make for the 964. 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. A single length mandrel bent header has been proven to crack under the severe stresses found on the race track during severe endurance events. The mandrel bending process actually 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, which will lead to power loss. Our primary tubing is segmented and welded under pressure with the use of forming gas. Forming gas actually 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. But we don't stop there, once the segmenting is completed, a tool is passed inside the header, which will actually grinds away any left-over slag. This process produces extremely durable headers with superior strength that ensures higher gas velocity and less exhaust gas restriction.

The header piping used in incorporates a 2 1/2” motorsports style merge collector. The collector smooths out exhaust flow and turbulence created from the 3 primary pipes merging into one. Collectors create more velocity, which reduces backpressure and creates torque. Many exhaust manufacturers use “pyramid style” collectors or leave raw open-ended tubes, which create massive amounts of turbulence. Pyramid style collectors do a slightly better job than a raw tube but they still force air towards the flange. Our systems collector gently guides exhaust gases from the walls of the piping towards the center and lowest point of the 2 1/2” tubing. 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 EXHAUST CONNECTIONS are “AERO QUIP” connections. These “AERO QUIP” connections reduce weight as they only use one bolt and nut versus 3 found on most header / cat flanges. They also keep increase gas volume and gas velocity constant as the tubing diameter is kept consistent.

THE 100 CELL CATALYTICS are made with HJS cores. But we didn't stop there. They are 100 Cell HJS “HF” (High Flow) Tri-Metallic cats. They are meant for the track and will give you many, many years of service.

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, linear-firing-order dominated flat 6 Porsche sound, which also gurgles and crackles off throttle. It is the closest to a Cup Car sound in nature.

THE EXHAUST TIP is a 4.5” (116 mm) oval design and is double walled to dissipate heat, which means that it won't tarnish as quickly as single walled tips. The design fits the factory cut out in the bumper perfectly and is mounted via the “Aero-Quip” ball style-connecting joint so it can be perfectly adjusted and centered.

All of the points made above are far more time consuming to manufacture and add expense to our products. But we choose these methods to ensure maximum horsepower gains throughout a broad power band; all while maintaining reasonable sound levels with an exotic exhaust note that is purely Porsche.
