Frequently Asked Questions
Which years of the Giulia Quadrifoglio does the S-AR/TI/1H fit?The S-AR/TI/1H fits the 2017 through 2020 Alfa Romeo Giulia Quadrifoglio with the 2.9-liter twin-turbo V6 engine. It is specific to the Quadrifoglio trim and is not compatible with the standard Giulia, Giulia Ti, or Giulia Sport variants that use four-cylinder engines.
What are the verified power and torque gains from the S-AR/TI/1H?Akrapovic's dyno testing on the Giulia Quadrifoglio shows a gain of +6.0 kW (approximately 8 hp) at 6,950 rpm and +12.6 Nm of torque at 2,850 rpm compared to the factory exhaust. These gains are achieved without engine mapping changes, purely from the reduced exhaust backpressure and optimized flow of the Evolution Line system.
Is the S-AR/TI/1H a full titanium system or a mixed system?The S-AR/TI/1H uses grade-1 titanium for the muffler assembly and collector, while the link pipes connecting to the factory catalytic converter are manufactured from high-grade stainless steel. This mixed construction is an Akrapovic engineering choice that optimizes the thermal management requirements at the link pipe section while keeping the muffler as light as possible with titanium.
Does the S-AR/TI/1H affect the Giulia Quadrifoglio's warranty?Aftermarket exhaust systems may affect the manufacturer's warranty on emissions-related components. The S-AR/TI/1H retains the factory catalytic converter, limiting the scope of any warranty impact. We recommend confirming with your Alfa Romeo dealer if warranty preservation is a priority for you before ordering.
What sound character does the S-AR/TI/1H give the Giulia Quadrifoglio?The Akrapovic S-AR/TI/1H enhances the Giulia Quadrifoglio's already distinctive V6 twin-turbo exhaust note with a richer, more layered sound at all engine speeds. The system produces a more defined crack on upshifts and a deeper, more resonant rumble at cruise, while the full-throttle sound is substantially louder and more vocal than the factory unit. The character remains appropriate for road use without excessive drone.
Is the S-AR/TI/1H street legal in the United States?The S-AR/TI/1H retains the factory catalytic converter and is not a decat system, making it street legal in most US states. It does not carry a CARB Executive Order number, so buyers in California and other CARB-regulated states should confirm local emissions compliance before purchase.
Can the S-AR/TI/1H be installed with other Akrapovic components?Yes. The S-AR/TI/1H is designed to be part of a complete Akrapovic system for the Giulia Quadrifoglio. It is compatible with the Akrapovic downpipe set (DP-AR/SS/1) for additional performance gains. The two systems are developed together and can be combined for a complete Akrapovic performance exhaust solution.
How does the 4.1 kg weight reduction affect the Giulia Quadrifoglio?Removing 4.1 kg from the rear of the Giulia Quadrifoglio contributes to improved weight distribution by reducing mass at the tail of the car. On a vehicle already engineered with a 50/50 front-to-rear weight balance target, any rear mass reduction supports that goal and can improve steering precision and rear-end agility, particularly noticeable during spirited driving.
Installation Overview
- Allow the factory exhaust to cool completely before beginning any work on the Giulia Quadrifoglio.
- Raise and securely support the vehicle on a lift or rated jack stands with wheels chocked.
- Apply penetrating lubricant to all OEM exhaust mounting hardware and rubber hangers and allow a 15-minute soak.
- Disconnect the factory exhaust system at the catalytic converter outlet flanges.
- Release all rubber hangers and carefully lower the factory exhaust assembly.
- Install the Akrapovic S-AR/TI/1H section by section per the Akrapovic installation instructions, beginning at the catalytic converter outlet connection.
- Hang all rubber hangers and verify the system clears all chassis, suspension, and body components.
- Hand-tighten all hardware, then torque to specification per the Akrapovic installation sheet.
- Start the vehicle and inspect all joints for exhaust leaks. Re-torque after the first full heat cycle.
