Fabspeed STREET Valved Supersport X-Pipe Exhaust System. Porsche 991.2 Twin Turbo / Turbo S (2017-2020)  ›  FSPOR9912TSSSXVQ

Fabspeed STREET Valved Supersport X-Pipe Exhaust System.

The Fabspeed Valved Supersport X-Pipe Exhaust System is a complete high-performance exhaust upgrade developed for the Porsche 911 991.2 Turbo and Turbo S from 2017–2020.

Fits:

• Porsche 991.2 Turbo Coupe 3.8L (540 Bhp) 2017-20
• Porsche 991.2 Turbo S Coupe 3.8L (580 Bhp) 2017-20
• Porsche 991.2 Turbo Cabriolet 3.8L (540 Bhp) 2017-20
• Porsche 991.2 Turbo S Cabriolet 3.8L (580 Bhp) 2017-20

Designed to provide two distinctly different exhaust personalities from the same system, it combines a free-flowing centre X-pipe, premium Helical exhaust valves, replacement catalytic-converter or bypass sections, and Deluxe Quad Style exhaust tips.

With the exhaust valves closed, gases are routed through Fabspeed's 70 mm / 2.75-inch quad-resonated centre X-pipe, creating a more controlled and refined performance exhaust note suitable for lower-noise driving.

Open the valves and the exhaust follows a much more direct path, bypassing the centre X-pipe for a significantly louder and more aggressive GT2 RS-inspired exhaust character.

The system is manufactured from 14–16 gauge T304L stainless steel using CNC mandrel-bent tubing and is designed as a bolt-on replacement with no cutting or welding required.

Fabspeed currently lists performance figures of approximately:

+30 HP

+25 lb-ft of torque

Manufacturer-listed weight change: -8

Actual performance will vary with vehicle condition, catalyst configuration, engine calibration, fuel, ambient conditions and other modifications.

What This Product Does:
The Fabspeed Valved Supersport X-Pipe Exhaust System replaces the restrictive factory rear exhaust and catalyst arrangement with a freer-flowing performance system.

It is designed to:

• Reduce exhaust restriction.
• Improve post-turbo exhaust flow.
• Increase horsepower and torque potential.
• Improve throttle response.
• Enhance turbocharged engine response.
• Provide two selectable exhaust sound levels.
• Reduce weight compared with the original system.
• Produce a more aggressive flat-six exhaust note.
• Retain quieter operation when desired.
• Support additional engine and performance modifications.
• Upgrade the rear appearance with Deluxe Quad Style Tips.

Symptoms Of Wear Or Failure:
Possible symptoms include:

• Exhaust rattling.
• Blowing or ticking noises.
• Visible exhaust leaks.
• Soot around joints.
• Cracked welds.
• Loose clamps.
• Damaged pipework.
• Unusual vibration.
• Exhaust tips moving or becoming misaligned.
• Unexpected increase or reduction in sound.
• Exhaust smell around the rear of the vehicle.
• Valve operation becoming inconsistent.

Why Replacement Matters:
Replacing a damaged or deteriorated exhaust system helps restore:

• Correct exhaust sealing.
• Intended X-pipe flow.
• Proper exhaust-valve operation.
• Correct quiet and loud modes.
• Structural integrity.
• Secure catalyst mounting.
• Proper exhaust-tip alignment.
• Safe containment of hot exhaust gases.
• Consistent engine performance.

A cracked or poorly operating performance exhaust may no longer provide the characteristics it was designed to deliver.
