Rather than modifying a single area of the vehicle, the package combines several complementary performance components to improve the way the twin-turbocharged V8 draws in air, expels exhaust gases and manages engine performance.

The package includes Maxflo Performance Mufflers with Deluxe Quad Style Tips, Sport Catalytic Converters, Secondary Cat Bypass Pipes, a BMC F1 Replacement Air Filter.

Together, these components are designed to reduce intake and exhaust restriction, improve engine breathing, sharpen response, reduce weight and produce a deeper, throatier V8 exhaust note.

The Fabspeed exhaust components are manufactured from 14–16 gauge mirror-polished T304 stainless steel, and Fabspeed lists approximately 60 lb of weight reduction compared with the corresponding factory components.

What This Product Does:
An internal-combustion engine must efficiently draw in clean air and expel combustion gases.

This becomes especially important in a high-output twin-turbocharged engine, where both the intake and exhaust systems must handle substantial airflow under load.

The Fabspeed package addresses several areas simultaneously:

• BMC F1 Air Filter – improves intake airflow while maintaining engine filtration.
  
• Sport Catalytic Converters – provide a performance-oriented alternative to the original catalyst arrangement.
  
• Secondary Cat Bypass Pipes – eliminate the secondary catalytic converters to further reduce exhaust restriction.
  
• Maxflo Performance Mufflers – improve rear exhaust flow while creating a deeper V8 exhaust note.

The result is a coordinated performance package rather than a single-component upgrade.

Performance:
The current Fabspeed product listing specifies:

Horsepower: TBD
Torque: TBD
Weight Reduction: Approx. 60 lb

Because package-specific horsepower and torque figures are currently listed as TBD, numerical power gains should not be assumed.

Actual performance will depend on factors including:

• Engine condition
• Turbocharger condition
• Fuel quality
• Intake condition
• Exhaust configuration
• Other modifications
• Ambient conditions
• Testing equipment and methodology

It is primarily a comprehensive performance upgrade.

Reasons for upgrading include:

• Maxflo Performance Mufflers
• Sport Catalytic Converters
• Secondary Cat Bypass Pipes
• BMC F1 Replacement Air Filter
• T304 stainless-steel construction
• Approx. 60 lb manufacturer-listed weight reduction
• Reduced intake restriction
• Reduced exhaust restriction
• Improved engine breathing
• Increased performance potential
• Sharper response
• Deeper twin-turbo V8 sound
• Deluxe Quad Style polished exhaust tips
