Lease for as low as $/week
Porsche 991 Turbo / Turbo S – Titanium Valved Exhaust System
Grade 5 Titanium • Center X-Pipe • True Motorsport Tone
Overview
The 991 Turbo is the benchmark for all-around performance—but like every turbocharged Porsche, the stock soundtrack falls short. Valvetronic Designs fixes that at the source. Our system starts with CAD-designed, CFD-tested exhaust manifolds to sharpen pulse timing and raise pitch for a cleaner, more motorsport-inspired note. Downstream, a valved titanium rear section delivers dual personalities on demand—raw and unfiltered when you want it, refined and comfortable when you need it.
Sound Dynamics
-
Valves Open: After the turbos, gases travel straight ~13 inches to atmosphere for an uncorrupted, razor-edged Porsche wail—crisp up top with aggressive shift pops.
-
Valves Closed: Flow is routed through two quad-chambered mufflers for a substantial drop in volume and a calm cabin demeanor.
-
Center X-Pipe: Smooths pulse interaction, kills drone, and adds a polished, high-frequency character throughout the rev range.
