Race Exhaust System 996.2 - Brombacher Edition - Catalytic Bypass - With Turn Down Tips

Description

Our entire Brombacher Edition line of exhausts is manufactured by M&M Exhaust, GmbH in Germany. They manufacture a multitude of Porsche Motorsport, Porsche Race Exhausts and Porsche Street Exhausts. Each system is manufactured in the highest-grade German V2A - X5CrNi18-10 - 1.4301 (T-304 L) light weight stainless steel and is tested comprehensively for exhaust gas scavenging, velocity, thermal stress, cracking and longevity. M&M exhausts have competed in and won many races over the years including Nürburgring, Le Mans, Dubai, Daytona to name a few. When you purchase this exhaust system, you are the benefactor of all that Porsche racing exhaust design experience. If you are looking for an exhaust product that can handle abuse at the track, look no further.

The headers start with a laser cut, stainless steel, dual plated primary flange which is more labor intensive to manufacture. M&M's race experience with thick, single plated flanges warping with age, heat and vibration lead to costly performance losses which prompted them to engineer a more reliable design. Their double plated flange allows for greater thermal expansion which dissipates heat more efficiently, which equates to greater reliability on the track or street. The hand ported primary inlets are also more labor-intensive, but hand porting means more laminar flow which equates to greater exhaust gas velocity and more performance. The inlets lead us to the long tube, equal length primary tubing whose diameter is selected and designed specifically for your engine's displacement. Each primary tube is mandrel bent, segmented and purge TIG welded by hand. For those thinking, why aren't the primaries a seamless length of tubing like some others in the industry? Segmenting strengthens the primaries and prevents stress cracks commonly found with the competition's headers. M&M back purge TIG welds each joint which reduces carbide precipitation and means seamless internal welds for more laminar flow and greater performance. This primary design method has been proven over years of time under the toughest endurance racing conditions. The primary tubing leads us to the custom made, purge TIG welded, internally blended merge collector that smoothly transitions into larger diameter hand ported outlet for greater scavenging effect. The merge collector incorporates a small spike (not a long pyramid spike which can warp with heat and age) at the center which helps to scavenge the flow from each adjacent pipe as the engine fires in sequence. But another key to the merge collector is the larger outlet diameter which increases exhaust gas velocity and broadens the engine's torque curve all the way to the horsepower peak.

The bypass begins with an RSR style flared connection that has an expansion joint which is secured via springs. This is a high-end motorsports trick that prevents cracking, adds durability and simplifies installation. The bypass portion is hollow but visually appears like it has catalytic converters. After the bypass, the pipe paths are kept separate but are welded together for strength, M&M found that configuration made more performance gains than an X pipe design. The post cat O2 sensors are added just before the bend which allows for simple connection with the existing wiring. The piping then smoothly transitions into the tip with another RSR style clamp for simple installation.

The exhaust tips are 3.5 inches (90 mm) dual round outlets that perfectly complement the rear bumper cutout. Each tip can be turned down to reduce decibels.

Please note: This race system is not C.A.R.B. certified (California) nor is it TÜV approved or EPA certified and cannot be used on the street. We recommend FVD software tuning, as stock tuning will throw a check engine light (CEL) and will cause the car far to rich. This is the perfect time to take advantage of our FVD Progressive Tuning Program, explained in our performance software options. And please don't forget, if you already have FVD performance software, this exhaust purchase includes a free software update!
