Milltek Sport Alfa Romeo Giulia Quadrifoglio 2.9 V6 Bi-Turbo Catback Exhaust System

The Giulia Quadrifoglio's twin-turbo V6 carries genuine Ferrari-derived engineering heritage, powering one of the most rewarding sport sedans currently on sale, and the factory exhaust, while far from bad, leaves real room for improvement in both flow and character. Milltek Sport's Cat-Back exhaust replaces everything from the catalytic converter rearward, engineered to deliver genuine gains in flow, sound, and weight over the factory system.

Constructed entirely from T-304 stainless steel, this system is built to outlast the car itself, resisting the corrosion that eventually catches up with mild steel factory systems, especially through wet European winters. Milltek's own sound engineers spend considerable time tuning each system's resonance and tone, striking a genuine balance between letting this genuinely special V6 sing and avoiding the drone that can plague poorly engineered aftermarket systems on a long motorway drive.

Please select your exhaust tip finish at checkout: GT 100mm Polished, GT 100mm Cerakote, GT 100mm Titanium, GT 100mm Burnt Titanium, or JET 100mm Carbon Fibre. All options deliver the same underlying performance and sound characteristics, the choice comes down to your preferred finish and how it complements the rest of your car.
