The Akrapovic Slip-On Race Line (Titanium) is a precision-engineered exhaust system that brings out the true character and performance of the Porsche 911 Turbo / Turbo S 992.1. Crafted entirely from lightweight, high-grade titanium, this system is designed to enhance every aspect of the driving experience—from sound and performance to weight savings and aesthetics. More than just an exhaust, it’s the finishing touch the 911 Turbo deserves and how it should have come from the factory. With motorsport-inspired engineering and a focus on lightweight performance, this system sets a new benchmark for track-focused upgrades.
The Akrapovic Slip-On Race Line transforms Porsche’s iconic flat-six engine sound, delivering an unmistakable acoustic experience. At lower revs, it produces a deep, raw rumble that transitions to a strong, rich tone in the mid-range, culminating in a high-frequency sensation at higher revs. This thrilling sound profile is perfectly timed to upshifts, providing an exhilarating experience in the higher gears, while race-inspired burbles accompany downshifts. Precision-engineered with a carefully calculated H-link between the main pipes, the system eliminates intrusive droning and unwanted flow noise, ensuring a dynamic yet comfortable cabin experience.
Dyno testing shows gains of +22.6 hp at 3,400 rpm and +34.5 ft-lb of torque at 3,400 rpm compared to the Porsche stock sports exhaust system. The lightweight titanium construction achieves a substantial weight reduction of 9.0 kg, making it 60.5% lighter than the stock exhaust.
