The Scart range
Sport, Super Sound, valves - every Scart exhaust belongs to one of these families. Our proposal: a singular voice, not a weighted average of every expectation in the world. Here's how that voice is articulated, and how to choose the one that will reveal your car's character.
Stock
The original system, calibrated for compliance, restrained.
Sport
More character, no excess. Always civilized.
Super Sound
The full signature: Riva (deep, guttural) or Ultima (twin-tone without valves).
Alongside, every model also exists in a valve version - to get both worlds in one car.
Raw, present, civilized.
The Sport range sits between stock and our Super Sound. The sound is more expressive, rawer, more present - yet always civilized. It's the right choice for those who want to bring out their car's character without going all the way to the full Super Sound signature.
It is offered across most of the catalogue, both as a full system and as Sport pre-silencer - every reference is designed to preserve the Sport grain wherever it sits in the exhaust line.
The umbrella name for the full signature.
Super Sound is the umbrella name for our most expressive non-valve range - the one that fully reveals the engine's voice. Depending on the model, it takes one of two shapes:
Deep. Guttural. Noble.
The Riva name comes from Martin's teenage discovery of Riva boats in a documentary at age 15. That signature names our non-valve exhausts with the deepest, most guttural voice.
Riva applies mainly to vintage Porsches - that's where the signature warble and noble presence of the air-cooled flat-six come alive. It's not a boat sound, it's a Porsche sound, with the depth Riva evokes.
For example, no Riva on the 991.
Twin-tone. No moving parts.
Ultima applies mainly to more recent Porsches - that's the historical trajectory the range has taken. It's also our technical tour de force: a twin-tone sound without any moving parts. At cruise, exhaust flow passes through a baffle that softens the note - you drive discreet. Under acceleration, rising pressure in the muffler neutralizes the baffle and routes gas straight to the outlet.
The result: sound is decoupled from engine RPM. At a steady 5,000 rpm on the motorway you stay discreet; at 3,000 rpm under load, the exhaust sings.
Zero rockwool inside the muffler: no acoustic ageing over time.
Two cars in one.
Our valve systems run alongside for most models. With valves closed, you keep a discreet, near-stock note with the Scart signature texture layered on top. With valves open, the sound is unleashed - deep, aggressive, ferocious, the voice of a race car.
Worth noting: on some models, Porsche offers a factory valve system. But these are calibrated for a global standard, so fairly discreet on the whole - sometimes well done (981), sometimes missed (997.2). Our systems bring something else: the same flexibility, but with the Scart signature at the open end.
"Inside a Scart valve exhaust, there are two acoustic paths in the same box. One built for sound, one built for restraint. The valve switches between the two. It's not a direct outlet popping out from under the car - a direct outlet produces decibels, but no depth. And depth is what makes the beauty of the sound."
- Martin Scart
The standard control is a discreet switch fitted into the door sill trim, included in the price. Two upgrade options: a pair of remotes (€145 incl. VAT), or the OEM Porsche switch-bar kit (€340 incl. VAT) for seamless integration - supplied with its harness that removes the automatic shutoff between 45 and 75 km/h on applicable models.
Not every model receives every variant - for example, no Riva on the 991, no Ultima on the 997.2. The best path forward is to talk: tell us about your taste, how you use the car, and we'll guide you to the right configuration.
