Sound Character

The Turbo S is brutally fast—this system makes it sound just as serious.

Why This System

The 991 and 992 Turbo S are engineering benchmarks—but the factory exhaust doesn’t reflect their full potential. This X-pipe catback system refines and amplifies the experience, delivering a more exotic tone, improved flow, and sharper response without sacrificing daily usability.

For owners who want their Turbo S to sound as fast as it is—this is the upgrade that completes the package.
