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 997.1/ 997.2 GT3 and 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 GT3 RS 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.
