Maxflo Performance Exhaust System
Fabspeed's Maxflo Performance Exhaust for the Porsche 958 Cayenne S and GTS (2011-2014) opens up the factory exhaust for a throatier, deeper note through the rev range. Fabspeed's testing showed a gain of 8whp with improved throttle response. Built from 14-16 gauge CNC mandrel-bent T304L stainless steel, it includes Fabspeed's Deluxe Quad-Style Tips in polished chrome or X-50 style, and is also compatible with the factory OEM tips. Installation is mostly bolt-on, with minor cutting required at the factory exhaust's marked break point.
