Lightweight Competition Exhaust System
Fabspeed's Lightweight Competition Exhaust for the 718 GT4, GTS and Spyder (2020+) started as a 3D scan of the factory exhaust, rebuilt with 2.5-inch Bent over an internal mandrel so the tube keeps a constant diameter through the bend, unlike crush-bending. T304L stainless tubing and a crossover tube to aid scavenging and cut An unwanted droning resonance at certain highway rpm, where exhaust pulses match the cabin's natural frequency.. It deletes the factory PSE valves entirely, so it's aggressive at every rpm; turn-down tips are available to cut 3-6dB for track noise limits. Most of the power gain lands past 5000rpm, with Fabspeed's dyno testing showing 15whp and 10 ft-lbs of torque at 7700rpm. It saves 17 lbs (7.3kg) over the factory muffler, stays 50-state emissions legal with no check engine light, and installs DIY with no cutting or welding. Owners who'd rather not tackle it themselves can have Rennen Motorsport or an authorised dealer fit it instead.
