Product Description

 

 

The Fabspeed Supercup Race Exhaust System is a high-performance catback exhaust engineered for Porsche 981 Boxster and Cayman (2013–2016) models that prioritizes maximum sound and power legally available from a bolt-on upgrade. Designed with a straight-through flow path and TRUE X-pipe, this exhaust produces a louder, more aggressive flat-six soundtrack and measurable horsepower and torque gains over stock while reducing rear-end weight. Featuring premium CNC mandrel-bent T304 stainless steel construction and high-quality tips in your choice of finish, it transforms both the auditory and dynamic experience of your 981 chassis on the street and track.
