Replacing the original catalytic-converter section, the system combines 200-cell HJS high-flow Sport Catalytic Converters with a specially designed stainless-steel cast X-pipe featuring a knife-edged internal design. The result is a less restrictive exhaust path that allows gases from the naturally aspirated GT3 flat-six to flow more efficiently through the exhaust system.

Manufactured using mandrel-bent T304L stainless steel, the system is designed as a direct bolt-on performance upgrade requiring no cutting or welding.

Fabspeed reports gains of up to 15 wheel horsepower, together with approximately 14 lb-ft of torque and a 12 lb weight reduction compared with the factory components. Actual results depend on the individual vehicle and testing conditions.

What This Product Does:
The catalytic converters sit within the exhaust system and process exhaust gases before they leave the vehicle.

At the same time, their internal construction creates some resistance to exhaust flow.

A performance Sport Cat system aims to maintain catalytic treatment while reducing unnecessary restriction compared with the original catalytic-converter arrangement.

The Fabspeed Sport Cat X-Pipe is designed to:

• Improve exhaust-gas flow
• Reduce exhaust restriction
• Improve throttle response
• Increase horsepower and torque potential
• Reduce exhaust-system weight
• Produce a more defined GT3 exhaust note
• Provide a mild increase in exhaust volume
• Retain catalytic exhaust treatment
• Improve exhaust flow between the two cylinder banks

Power: +15 WHP
Torque: +14 lb-ft
Weight Reduction: Approx. 12 lb

These are manufacturer-reported figures and should not be interpreted as guaranteed gains for every vehicle.

Actual performance can vary according to:

• Engine condition
• Existing exhaust configuration
• Headers
• Rear muffler system
• Intake modifications
• Engine calibration
• Fuel quality
• Ambient conditions
• Vehicle specification
• Dyno equipment and testing procedure

The Fabspeed Sport Cat X-Pipe is primarily a performance upgrade designed for drivers seeking improved exhaust flow without moving to a completely catless exhaust section.

Reasons for upgrading include:

• 200-cell HJS Sport Catalytic Converters
• Reduced exhaust restriction
• Cast stainless-steel X-pipe
• Knife-edged X-pipe design
• Improved exhaust-gas flow
• Improved throttle response
• Manufacturer-reported gains up to +15 WHP
• Manufacturer-listed +14 lb-ft torque
• Approx. 12 lb weight reduction
• More defined GT3 exhaust sound
• Mild increase in exhaust volume
• T304L stainless-steel construction
• Mandrel-bent tubing
• Direct bolt-on installation
• No cutting or welding required
