APR's cat-back exhaust for the 992.1 Porsche 911 Carrera 3.0T is a full T304 stainless steel quad-exit system with dual 3in valved paths and dual 2in non-valved paths. The non-valved paths are 66% larger in cross-section than stock and the valved paths 19% larger, yet the system weighs 37% less than the Porsche Sport Exhaust (17 lbs versus 27 lbs). Short valved paths minimize backpressure and maximize velocity at wide-open throttle, while cast T304 valve housings use the factory ECU valve actuation and a drone-eliminating muffler keeps cruising civilized. It fits both base and PSE-equipped cars, with CNC-mandrel-bent brushed tubing and CNC-cut precision bracketry for a two-clamp install.
