Valvetronic Designs Valved Sport Exhaust System for 991.1 Porsche 911 Carrera / S / GTS

Valvetronic Designs presents its Cat-Back Exhaust System for the Porsche 991, engineered from the ground up to deliver a truly rich, F1-inspired soundtrack while preserving comfort and refinement with the valves closed. A large center X-pipe balances pulses and smooths flow, blending aggression with sophistication for the definitive 991 exhaust note.

Sound Dynamics

• With the valves open, Valvetronic Designs delivers a minimally restricted, sharp, high-pitched F1-style timbre that turns the Porsche into a true motorsport machine; with the valves closed, output is significantly tempered, unwanted cabin frequencies are reduced, and the experience becomes calm and refined for daily use. The result is a meticulously tuned balance of raw emotion and everyday usability—maximum enjoyment without compromise.
