When the 991.1 generation 911 was replaced by the 991.2, Porsche added twin turbos that muted much of the drama and emotion from the exhaust note. At Valvetronic Designs, we believe sound is the foundation of driving passion—and our exhaust package restores the raw emotion your Carrera deserves.
Sound Dynamics
Valves Open – Exhaust gases flow almost completely unrestricted. After passing through the turbos, the system channels them through our valved muffler, into a large X-pipe, and out the tips. The result is an extremely raw, motorsport-inspired tone that reconnects the 991.2 to Porsche’s naturally aspirated roots.
Valves Closed – Sound is routed through dual quad-chamber mufflers, significantly reducing volume for quiet cruising, early mornings, and long drives.
Upgraded Exhaust Manifolds – Regardless of configuration, our CAD-designed and CFD-tested manifolds increase exhaust pitch and bring back the signature emotion missing from the stock 3.0TT setup.
