Product Description

 

 

The Fabspeed Supercup Turboback Exhaust System delivers an extreme transformation in sound, flow, and performance for the Porsche 718 platform. By replacing the restrictive factory rear exhaust and catalytic converter assembly with a high-flow, 3-inch straight-through system, this package unlocks sharper throttle response, quicker turbo spool, and a dramatically more aggressive exhaust tone. Built from thick-wall T304L stainless steel and engineered with motorsport-grade TIG welds, the system is designed for durability under heat and demanding driving. Whether configured with a high-flow sport catalytic converter or a full cat-bypass for maximum output, the Supercup system is one of the most effective upgrades for drivers seeking raw performance and a visceral turbocharged soundtrack.
