The Missing Half That Unlocks the Full Giulia Quadrifoglio Evolution System
The Akrapovic E-AR/T/1 Evolution Link Pipe Set (Titanium) is the essential companion component to the S-AR/TI/1H muffler set, completing the full Akrapovic Evolution Line installation on the 2017-2020 Alfa Romeo Giulia Quadrifoglio. Because of packaging requirements, the Evolution system for the Giulia Quadrifoglio is shipped as two separate part numbers. This E-AR/T/1 link pipe set connects the catalytic converters to the rear mufflers, replacing the factory connecting pipes with Grade 1 titanium construction that delivers reduced backpressure, improved exhaust flow across the 2.9L V6 Biturbo powerband, and measurable weight savings of approximately 0.70 kg over the factory pipes. Weighing just 1.30 kg for the complete set, the E-AR/T/1 represents the performance foundation of the full Akrapovic Evolution build for the Giulia Quadrifoglio.
Key Features
- Grade 1 Titanium Construction Ultra-lightweight, corrosion-resistant titanium throughout the E-AR/T/1 set ensures long-term durability in all conditions with a 0.70 kg advantage over stock pipes.
- Complete Set Weight of 1.30 kg Both link pipes together weigh just 1.30 kg, directly reducing exhaust system mass and contributing to the Giulia Quadrifoglio's front-rear weight distribution.
- Mandatory Companion to S-AR/TI/1H The E-AR/T/1 and S-AR/TI/1H muffler set are both required to complete the Akrapovic Evolution Line installation on the Giulia Quadrifoglio.
- Reduced Backpressure Design Larger-diameter titanium piping promotes freer exhaust gas flow through the 2.9L V6 Biturbo, improving throttle response and mid-range torque delivery.
- Bolt-On Installation Precision-engineered to direct OEM mounting points on the Giulia Quadrifoglio chassis with no cutting or welding required.
- Enhanced Exhaust Character Paired with the S-AR/TI/1H, the E-AR/T/1 produces the deeper, more refined exhaust tone the Giulia Quadrifoglio V6 is capable of.
- Non-CARB Compliant Designed for performance use. Not for sale in California or other states that follow CARB emissions regulations.

Frequently Asked Questions
Why does the Akrapovic Evolution system for the Giulia Quadrifoglio ship in two separate part numbers?Due to packaging size requirements, Akrapovic split the Evolution Line for the Giulia Quadrifoglio into two SKUs: the E-AR/T/1 link pipe set and the S-AR/TI/1H muffler set. Both must be ordered and installed together to complete the full Evolution Line system. The E-AR/T/1 alone is not a standalone exhaust upgrade.
Does the E-AR/T/1 fit all Giulia Quadrifoglio model years?Yes. The E-AR/T/1 fits the 2017-2020 Alfa Romeo Giulia Quadrifoglio equipped with the 2.9L V6 Biturbo engine. This covers the complete US production run of the Giulia Quadrifoglio sold under this generation.
What performance gains can I expect from the E-AR/T/1 and S-AR/TI/1H together?When installed as a complete pair, the Akrapovic Evolution system promotes freer exhaust gas flow through the 2.9L Biturbo, reducing backpressure and improving throttle response, mid-range torque, and top-end power output. The titanium construction also reduces exhaust system weight by approximately 0.70 kg for this link set alone.
Is the E-AR/T/1 legal to use on public roads in California?No. The E-AR/T/1 is not CARB-compliant and is not for sale or use in California or other states that follow California's emissions regulations. It is intended for performance applications in applicable states only.
Can I install the Akrapovic E-AR/T/1 without removing the catalytic converters?Yes. The E-AR/T/1 link pipes connect the existing catalytic converters to the Akrapovic muffler set (S-AR/TI/1H) and do not require catalytic converter removal. The cats remain in place; only the connecting pipe sections between cats and mufflers are replaced.
Do I need a tune after installing the E-AR/T/1 and S-AR/TI/1H on my Giulia Quadrifoglio?The Akrapovic Evolution system is designed as a direct-fit upgrade that does not require an ECU tune for installation. However, many Giulia Quadrifoglio owners choose to pair a tune with the exhaust upgrade to fully optimize the power gains made possible by reduced backpressure.
Is professional installation required for the Akrapovic E-AR/T/1?The E-AR/T/1 is engineered as a bolt-on installation at OEM mounting points with no cutting or welding. Experienced DIY mechanics with lift access and basic exhaust tools can complete the installation. Professional installation is recommended for first-time exhaust installers to ensure proper gasket seating and torque specification compliance.
What warranty comes with the Akrapovic E-AR/T/1?Akrapovic provides a 2-year manufacturer warranty covering defects in materials and workmanship under normal use conditions. The warranty does not cover damage from improper installation, track or racing use, or use in violation of emissions regulations.
How does the titanium construction compare to the factory steel link pipes?The E-AR/T/1 titanium link pipes are approximately 0.70 kg lighter than the OEM steel connecting pipes. Titanium also offers superior corrosion resistance and maintains structural integrity at higher temperatures than steel, making it the preferred material for high-performance exhaust applications on track-capable vehicles like the Giulia Quadrifoglio.
Installation Instructions
- Allow the vehicle exhaust system to cool fully before beginning work.
- Safely lift the Giulia Quadrifoglio on a vehicle lift and support securely.
- Remove the factory connecting pipes between the catalytic converters and rear mufflers.
- Install the E-AR/T/1 titanium link pipes using the included gaskets and mounting hardware.
- Hand-tighten all connections and confirm proper alignment before final torque.
- Also install the S-AR/TI/1H muffler set to complete the Evolution Line system.
- Torque all hardware to specification per Akrapovic's included instruction sheet.
- Lower the vehicle and start the engine to inspect for leaks and confirm all connections are secure.
