The ultimate OEM style, high performance, replacement muffler for your GT3!
As many GT3 owners know, the OEM mufflers are prone to cracking, breaking and blowing out, particularly the titanium mufflers on GT3RS cars.
Fabspeed wanted to design a replacement muffler that not only fixed that issue but also improved on the OEM design.
Using 25+ years of air and water-cooled experience, they 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 GT3 pitch for the signature GT3 CUP car sound.
Then, Fabspeed implemented their signature investment cast X-pipe for optimal exhaust scavenging. 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, they mimicked Porsche’s 7 chamber design. This makes for a completely drone free muffler, even when running cat-less race headers.
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 the signature X-pipe.
POWER:
On the 991.1 GT3RS test car, paired with side muffler bypass pipes, the Rennsport muffler picked up an impressive 27 lb/ft of torque down low at 3,200 RPM.
From 2,900 RPM all the way to 5,700 RPM it picks up 10 wheel horsepower or more, and peak wheel horsepower is up from 446 to 454.
That’s a gain of 8 wheel horsepower or 9 HP at the crank.
