FABSPEED Porsche 964 Carrera Maxflo Cat-Back Exhaust System (1989–1994)

The Fabspeed Maxflo system replaces the restrictive factory center and secondary mufflers with a lightweight, free-flowing T304L stainless-steel muffler mounted behind the license-plate area. It delivers a deeper flat-six tone, improved response, reduced heat, and significant rear weight savings while remaining suitable for street use.

Fitment: Porsche 964 Carrera C2, C4, RS America, Euro RS, and Speedster, model years 1989–1994.

• Single- or dual-outlet configurations
• 14–16 gauge CNC mandrel-bent T304L stainless steel
• Includes polished 4-inch oval outlet tip(s), mounting brackets, straps, and cap-off hardware
• Published Fabspeed dyno result: up to +15 hp and +12 lb-ft
• Approximate weight reduction: 24 lb / 11 kg

Installation note: Adding the left-side outlet may require rear-bumper modification on narrow-body cars; wide-body dual-outlet cars do not require this modification.
