Fabspeed Valved Center Muffler Bypass X-Pipe. Porsche 991.2 Carrera (Non-PSE Only)  ❭  FSPOR9912VLV

The Fabspeed Porsche 991.2 Carrera Valved Center Muffler Bypass X-Pipe is a performance exhaust upgrade developed specifically for 2017–2019 Porsche 991.2 Carrera 3.0L twin-turbo models originally equipped without Porsche Sport Exhaust (PSE).

Fits:

• Porsche 991.2 Carrera 2 3.0L (370 Bhp) 2016-19
• Porsche 991.2 Carrera 4 3.0L (370 Bhp) 2016-19
• Porsche 991.2 Cabriolet 2 3.0L (370 Bhp) 2016-19
• Porsche 991.2 Cabriolet 4 3.0L (370 Bhp) 2016-19
• Porsche 991.2 Targa 4 3.0L (370 Bhp) 2016-19  

The system replaces the large factory centre muffler section with a freer-flowing valved X-pipe arrangement, giving non-PSE cars the ability to switch between a more restrained exhaust character and a significantly more aggressive sports-car sound.

Manufactured from polished T304L stainless steel, the system uses premium UK-manufactured Helical vacuum-actuated exhaust valves and includes Fabspeed Deluxe Dual Style exhaust tips in a choice of finishes.

Fabspeed currently publishes:

• +17 horsepower
• +23 lb-ft torque
• 10 lb / 4.5 kg weight reduction

For a mechanically healthy vehicle, this product is primarily a sound, performance and weight-reduction upgrade, rather than a maintenance replacement.

What This Product Does:
The factory centre muffler reduces exhaust noise and provides the refinement expected from a standard road car.

The Fabspeed Valved Center Muffler Bypass replaces this restrictive centre section with a freer-flowing X-pipe and controllable exhaust valves.

The system is designed to:

• Increase exhaust flow
• Reduce centre-muffler restriction
• Increase exhaust sound
• Provide two different exhaust sound levels
• Increase horsepower and torque
• Reduce exhaust-system weight
• Enhance turbocharged flat-six character
• Retain the factory catalytic converters
• Maintain a direct bolt-on layout
• Upgrade the visible exhaust outlets with Deluxe Dual Style tips

Possible symptoms of deterioration include:

• Metallic rattling
• Internal muffler buzzing
• Exhaust blowing
• Hissing noises
• Cracked welds
• Corrosion
• Loose mounting brackets
• Black soot around leaking joints
• Exhaust vibration
• Muffler movement
• Exhaust tips sitting out of alignment
• Unexpected increase in exhaust noise

A metallic noise should be diagnosed carefully because heat shields, clamps or neighbouring exhaust components can cause similar symptoms.

Why Replacement Matters:
If the original centre muffler is physically damaged or leaking, replacement helps restore:

• A sealed exhaust path
• Correct exhaust alignment
• Secure mounting
• Controlled exhaust noise
• Proper clearance from surrounding components

However, if the original muffler is still healthy, installing the Fabspeed system is primarily an upgrade for sound, performance, valve control and weight reduction.
