Description

This system is designed for those looking for performance and a more exotic sound than the Porsche Sport Exhaust (PSE) can deliver. It is manufactured for performance across the entire rev range with an exhaust note that is rooted in motorsport yet offers daily driver comfort at the touch of a button. With the valves open, the sound is unmistakably RSR like in the lower rpms with a Cup car like high pitched scream up top. Off throttle you will experience aggressive gurgling and crackling, which completes the exotic motorsport experience. This is one of the most exotic systems offered by FVD and is the perfect compromise for comfort and sound. Also consider that the FVD brand offers you far more exclusivity than most tuners. Stand out at your next track or coffee meet and watch the looks of envy when your friends hear this exhaust.

The long tube equal length 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. Next, look at the hand ported primary inlets, again, this is a more labor-intensive method, 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 on these high fuel pressure DFI motors) 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 collector outlet is connected to the catalytic converters via a round RSR style aero-quip clamps. Those connections are proven to keep the flow more laminar after it exits the collector and increases velocity and scavenging effect over the commonly found triangular style flanges used by the competition.

The catalytic cores used in this system are the most advanced in the industry. They are produced by HJS in Germany and are a 200 CPSI (cell per square inch) tri-metal design. Tri-Metal cats are the freest flowing and environmentally friendly aftermarket cats produced today. Tri-metal catalytic converters are Rhodium, Platinum and Palladium coated and perform all three necessary and mandated reactions to prevent pollution. Reduction of nitrogen oxides to nitrogen and oxygen, oxidation of carbon monoxide to carbon dioxide and oxidation of unburnt hydrocarbons to carbon dioxide and water simultaneously. But we didn't stop there with these catalytic converters; we also opted for the most expensive HJS “HD” cores. The new generation of HJS high performance catalysts is characterized by 30 % less weight and 15% less backpressure. They are nicknamed “HD” for high durability matrix design catalytic converters. They have a “SM-matrix” (winding of three flat and corrugated foils) and a special connection to the matrix sheath (see picture below), which equates to extremely high flow and durability for track and street use. Many of our competition simply state the cells per square inch or “German Cats” but they are not specific as this portion of any exhaust system is THE MOST EXPENSIVE component. We choose to include the best cores available on the market to ensure years of trouble-free operation, reduce weight, increase horsepower and protect the environment.

The muffler design varies greatly from designs that are common in the aftermarket. Our muffler is 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. This design isolates and dampens the unwanted frequencies that create drone. Perforated tubes also create 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 exhaust tips are 3.5 inches (90 mm) dual round outlets that perfectly complement the rear bumper cutout. Each tip is double walled stainless which dissipates heat more efficiently so that the tips don't discolor with heat as quickly as single walled tips. Each tip includes an embossed FVD Brombacher logo.

Please note: If you are replacing a Porsche Sport Exhaust (PSE) system you can reuse the factory vacuum lines and hook them up directly to this system. If you do not have the Porsche Sport Exhaust (PSE) Option, you would require the valved exhaust retrofit kit, part # BESKLS000001 and the optional remote key fob, part # BESKLS0000FB. We recommend new gaskets, 2 Qty. 99711110731 and 18 Qty. header bolts 99907353501 for installation, everything else is included. We recommend software tuning with the addition of sport cats, as stock tuning can cause the car to run rich. That can lead to raw fuel being dumped on the cats, which can lead to damage and premature failure. This is the perfect time to take advantage of our FVD Progressive Tuning Program, explained in our performance software options. If you already have FVD performance software, this exhaust system purchase includes a free FVD software update. Sport cats are not C.A.R.B. certified (California) nor are they TÜV approved or EPA certified. They are for Racing use only.
