Fabspeed Primary Maxflo Exhaust System for 964 Porsche 911 Carrera / 4 / RS America / Speedster
Fabspeed’s Primary Maxflo Exhaust System for 964 Porsche 911 Carrera replaces the factory muffler with a deep, throaty flat-six tone that stays at a volume you can live with every day. Built with the same air-cooled character in mind as Fabspeed’s louder Primary Muffler Bypass, the Maxflo trades some of that bypass’s aggression for daily drivability, sharpening throttle response through the RPM range without turning the cabin into a drone chamber. It’s available in a single or dual outlet configuration, so you can match the look and sound to how the car will actually be driven.
Features
- Increases throttle response throughout the RPM range with a less restrictive muffler design
- Available in single or dual outlet configuration, selected at time of order
- Constructed from 14-16 gauge CNC mandrel-bent T304L stainless steel
- Includes 4″ / 102mm oval-style tips for a clean fit against the factory bumper
- Simple DIY bolt-on installation, no cutting or welding required
- Backed by the Fabspeed lifetime warranty
Applications
- Porsche 911 Carrera: 964 | 1989-1994 | 3.6L F6

- Porsche 911 Carrera RS America: 964 | 1993-1994 | 3.6L F6
- Porsche 911 Carrera Speedster: 964 | 1989-1994 | 3.6L F6
Notes
- All Fabspeed products are expected to ship within one week of order, though timelines are often much quicker
- Choosing dual outlets requires slight modification to the factory rear bumper for proper fitment of the second outlet
- A block-off cap is included to cap off the left-side outlet when running a single outlet
- To upgrade to dual outlets later, purchase the second outlet tip, then cut a second hole through the rear bumper cover to install it
Frequently Asked Questions
- Will the Fabspeed Primary Maxflo Exhaust System fit my 964 Carrera, Carrera 4, RS America, or Speedster? Yes. It’s a direct bolt-on fit across the 1988-1994 964 Carrera range, available in single or dual outlet configuration to match your car.
- What’s the difference between the single and dual outlet configurations? Both use the same muffler; the difference is how the exhaust exits the car. Dual outlets require a small modification to the factory rear bumper to open a second hole, while single outlet uses a block-off cap on the left side and needs no bumper modification.
- Can I switch from single to dual outlet later? Yes. Purchase the second outlet tip, then cut a second hole through the rear bumper cover to install it. The reverse isn’t offered as a kit; a single-outlet block-off cap is included with every order.
- How difficult is the Fabspeed Primary Maxflo Exhaust System to install? It’s a simple, Level-1 DIY bolt-on installation. No cutting or welding is required for the exhaust itself; only the dual-outlet configuration needs the bumper modification described above.
- How does this compare to Fabspeed’s Primary Muffler Bypass? The Maxflo keeps a street-appropriate volume for daily driving with a deep, throaty tone; the Primary Muffler Bypass is the louder, more track-focused straight-pipe option. Owners who drive their 964 daily choose the Maxflo; owners chasing maximum sound and weight savings for track or autocross choose the bypass.
- Is the Fabspeed Primary Maxflo Exhaust System backed by a warranty? Yes. It’s backed by the Fabspeed lifetime warranty covering materials and workmanship.
