Fabspeed's Porsche 993 Supercup Exhaust System utilizes track-specific tuning to bring out aggressive sound and maximum performance for you 993 Carreras. After sampling many factory Porsche 993 Supercup race cars from 1994 to 1997, our engineers DUPLICATED the factory Porsche Motorsport cat-back exhaust which is a muffler bypass pipe. Fabspeed simply added a straight through resonator to allow maximum power BUT slightly attenuate the sound level of a pure straight pipe muffler delete. Joe Fabiani Fabspeed founder and president RAN the SUPERCUP exhaust all across East Coast tracks events and Club Races through the late 1990s to 2010. The 993 SUPERCUP exhaust is the lightest 100% most powerful 993 catback exhaust you can buy guaranteed. Supercup maximized performance during track and motorsport events BUT aggressive Street-Legal emissions compliant cat-back. The Fabspeed Motorsport Supercup exhaust designed by Porsche Motorsport for RACECARS and improved and slightly redesigned for street cars and fits all 993, 993RS, 993 CUP models worldwide. 


This system is going to be loud, aggressive, and put a smile on your face from ear to ear. It's very reminiscent of the 993 Supercup race cars.


This free-flowing straight through resonated design showed gains of + 18.75HP and ( _15HP to the wheels)  on our dyno at the top of the rev range when tested on our in-house dynojet.
