Fits: Porsche 911 (991).

On the 991, most of the sound lives in the rear centre muffler - which is why our valveless sport version is so convincing: it is our personal favourite, as an alternative to the valve version. A meaningful, sporty sound through rev changes, discreet and comfortable at cruising speed. The muffler body is adjustable, for a perfect fit during installation.

Fitting

Strictly original interfaces (inlets, outlets, dimensions): direct replacement, no modification
Average fitting time: around 6 hours including removal. The rear bumper must come off - it gives access to the air filters: a good opportunity to switch them to sport versions
A lift is preferable but not essential; tighten the nuts progressively

Silencieux Sport "Coup de Cœur" (Sans Valves) pour Porsche 991

Sur la Porsche 991, l'essentiel de la sonorité se trouve dans le silencieux central arrière. C'est pourquoi notre version Sport sans valves est si convaincante et représente notre "coup de cœur" comme alternative à la version à valves.

Sonorité & Avantages

>
Équilibre parfait : Offre une sonorité significative et sportive lors des changements de régime, tout en redevenant discrète et confortable en vitesse de croisière.

>
Ajustement facile : Le corps du silencieux est réglable, ce qui permet un ajustement parfait lors de l'installation.

>
Alternative disponible : Une version Sport à valves (Réf : SCA 991 3 2 VI ou VT) est également disponible pour ceux qui recherchent une plus grande amplitude sonore.

Installation & Caractéristiques

>
Montage "Plug & Play" : Le silencieux respecte toutes les interfaces d'origine (entrées, sorties, encombrement) et se monte en lieu et place de l'ancienne pièce, sans aucune modification.

>
Temps de pose moyen : Environ 6 heures, incluant la dépose de l'origine. Le démontage du pare-chocs arrière est nécessaire.

>
Conseil d'optimisation : Le démontage du pare-chocs donnant accès aux filtres à air, nous conseillons d'en profiter pour les remplacer par des versions sport.

>
Équipement requis : Un pont élévateur est préférable pour plus de confort, mais n'est pas indispensable. Le serrage des écrous doit se faire progressivement

Contenu du Kit

Pour garantir une installation dans les meilleures conditions, un kit de montage complet est inclus dans le tarif. Il comprend :

>
Les joints

>
La visserie en inox

>
Les écrous-freins tout inox

>
Les deux sangles de fixation

Before you order

How does the Ultima work without valves?

The Ultima delivers a twin-tone sound without any moving parts. At cruise, exhaust flow goes through a baffle that softens the note - you drive discreet. Under acceleration, rising pressure neutralizes the baffle and routes gas straight to the outlet. The result: sound is decoupled from RPM (discreet at a steady 5,000 rpm, expressive at 3,000 rpm under load). Bonus: zero rockwool inside our mufflers, so no acoustic ageing over time.

How does international shipping work?

What does it sound like?

Depending on the model, you get either a Sport signature (raw but civilized) or Super Sound Type Riva / Ultima (deep, sporty and noble under acceleration, discreet at stabilized speeds, no resonance). For valve models, two worlds in one: discreet with valves closed, roaring with valves open.

"What a pleasure to finally hear the exhaust note with this X-pipe! The 992 isn't the most expressive of Porsches, so a solution had to be found to go from a meow to a roar! Incredible cold start, excellent revving,..."

"My 986 Boxster S is transformed! Calm and discreet in its daily driving, all it takes is pressing the original button on the dashboard for it to become a ferocious beast. What a sound! Thanks, Brieuc!"
Philippe H.
"I had a Riva exhaust installed on my 1985 911 after having already installed a valved exhaust on my 997 4S. On my 997, the tunnels are fantastic. I also own a 360 Modena, and frankly, the comparison is in the 997's..."
