Fabspeed Porsche 991.2 GT3 / GT3 RS Rennsport Muffler (2017-2019)

The ULTIMATE OEM style high performance replacement muffler for your GT3 100% GUARANTEED to be the WORLDs BEST !                                                                                            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
