Fabspeed Rennsport Muffler. Porsche 991.2 GT3 / GT3 RS 2017-2019 ❭ FSPOR9912GT3RSM

As many GT3 owners know, the OEM mufflers are prone to cracking, breaking and blowing out, particularly the titanium mufflers on GT3RS cars. Fabspeed Motorsport Engineers design a GT3 primary muffler replacement that not only fixed that issue but also greatly improved on the OEM design in multiple measurable ways. Using our 30+ years of air and water-cooled experience, we took the valve open tubing to 2.75in / 70mm which is the optimal diameter for GT3 engines to have low restriction but maintain high velocity and high RPM GT3 pitch for the signature GT3 CUP car sound. Then, we implemented our signature investment cast 70mm 2.75" X-Pipe for optimal exhaust scavenging and maximum volumetric efficiency. The X merges the two cylinder banks without creating any restriction in exhaust flow. To maintain the factory muffler’s exhaust note and lack of drone, we mimicked Porsche’s 7 chamber design. This makes for a completely drone free muffler, even when running cat-less race headers! Using GT3 headers with cats or Fabspeed headers with HJS German EPA approved catalytic converters along with Fabspeed GT3 Side Muffler Muffler Bypass Pipes for the ultimate emissions compliant lightweight GT3 exhaust. Fabspeed's GT3 center muffler is guaranteed to NEVER BREAK or fail- and OUTPERFORM any other aftermarket GT3 center muffler. 100% made in house at Fabspeed.
SOUND:
This muffler will have a very similar tone to the OEM muffler, however, it will be a bit louder with PSE turned on. It will also sound a bit smoother and higher pitched thanks to our signature X-pipe.
POWER:
On our 991.1 GT3RS test car, paired with our Side Muffler Muffler Bypass Pipes, the Rennsport Muffler picked up an impressive 27 ft/lbs of TQ down low at 3,200 RPM. From 2,900 RPM all the way to 5,700 RPM it picks up =12 horsepower or more, and peak power at the wheels is up from 446 to 454! That’s a gain of over 12 HP at the crank- from simply swapping out the fragile restrictive OEM Porsche 997GT3 to the very latest 991.2 GT3 Titanium OEM factory mufflers. BEST ADVICE- but and install a Fabspeed GT3 center muffler and SAVE you fragile OEM GT3 muffler for Concours shows and restoration. All GT3 OEM mufflers BREAK & EXPLODE when driven long and hard enough.

Quality:
All SPORTS LABEL exhaust systems are made of aircraft quality 304 stainless steel inside and out.

Remus did not stop there, it offers one of the largest selection of tip designs which are of the highest quality on the market. They feature high grade 441 stainless steel. Why 441? It is more resistant to corrosion and surface rust than 304. The tips are also chrome plated to ensure a lasting shiny finish and moreover, they are resonated to ensure a drone free system.
Performance:
All SPORTS LABEL exhaust systems are engineered with performance in mind, they all feature straight through free flow designs to ensure as little resistance possible thus promoting great horsepower and torque gains. All of the SPORTS LABEL systems are tested for back pressure reduction and REMUS GmbH uses it's own roller type dynograph to ensure positive wheel power gains on most of the models.
Sound:
All REMUS exhaust systems, from the Wild Labels to the Racing systems, are tested in an industry exclusive sound chamber. This allows REMUS GmbH to fine tune every single exhaust produced in order to meet the expectations of our demanding customers. All SPORTS LABEL exhaust systems are TUV approved and are thus legal for road use in Europe*. The decibel level is very close to stock/OEM however the sound characteristics are altered to offer a deep and refined tone absent in the factory exhaust system.
Every SPORTS LABEL exhaust system features the following:
• Straight through free flow design
• TUV approved*
• Made from 304 stainless steel inside and out

A special rolling procedure is used. It is essential to remove deep scratches as any surface defects will be very noticeable on the finished product. it improves corrosion resistance. The polishing eradicates crevices where corrosive particles can lodge themselves.
END TIPS DESIGN - OE
The muffler must be used in conjunction with the original exhaust end tips
END TIPS NUMBER AND POSITION
1 + 1 AT THE SIDES
The tailpipes are located low down at the sides of the car. There is one tailpipe at each side.
MATERIAL - AISI 304 STAINLESS STEEL
A choice stainless steel ideal for aggressive environments where combustion emissions can cause serious chemical corrosion on other types of metal
MAIN PIPE DIMENSION - 65mm
This is the diameter of the main pipe of the exhaust system
EXHAUST VALVE - NO VALVE
The exhaust system does not include a valve and always guarantees the most impressive sound. If the standard system includes one, control of the valve by both the engine ECU and by the pilot via the specific control systems is no longer possible
