Supercup Exhaust System

Supercup Exhaust System for the Porsche 996 GT3 (1999-2005), a straight-through, track-focused system that's lighter than the factory setup and flows much better. It brings out the flat-six's full snarl and is significantly louder than Fabspeed's Maxflo exhaust, so it suits owners chasing a very aggressive exhaust note. Built from 14-16ga CNC mandrel-bent 2.25in T304L stainless steel tubing, and compatible with the factory catalytic converters or Fabspeed's Sport Cat X-Pipe. Simple DIY bolt-on installation, no cutting or welding required. Factory PSE tips are not compatible with this system. Owners who'd rather not tackle it themselves can have Rennen Motorsport or an authorised dealer fit it instead.
