Fits: all Porsche 964.

This by-pass version is a converter-free solution: a straight pipe with an integrated muffler, replacing the original converter for freer flow, more sound and a significant performance gain.

Performance

Power gain: +12 hp on a stock Porsche 964
The gain is 5 hp lower than our 100-cell sport converter: the very free flow reduces back-pressure

Fitting

Strictly original interfaces: fits without any modification, between the manifolds and the transverse muffler

Description détaillée

[Source : description site 07/2026 - pas de fiche technique d'origine]

Cette version "by-pass" est une solution sans catalyseur, composée d'un tube direct et d'un silencieux intégré. Elle est conçue pour remplacer le catalyseur d'origine, offrant un flux de gaz d'échappement plus libre, une sonorité accrue et un gain de performance significatif.

Performances et caractéristiques :

>
Gain de puissance : +12 cv sur une Porsche 964 d'origine.

>
Note sur la performance : Le gain est inférieur de 5 cv à notre version catalyseur sport 100cc, car la contre-pression est réduite par le flux très libéré.

>
Sonorité améliorée : Apporte un son plus présent et sportif.

>
Montage direct : Conçu avec les interfaces d'origine, il se monte sans aucune modification à la place du catalyseur, entre les collecteurs et le silencieux transversal.

Before you order

What does the "Sport" range mean?

The Sport range sits between stock and our Super Sound. The sound is raw, present, more expressive than the original system, yet always civilized. It's the right choice if you want more character without going all the way to the full Super Sound signature (Riva or Ultima).

What's the lead time for this part?

This part is handcrafted to order in our workshop near Paris. Expect 3 to 5 weeks from receipt of payment. We keep you posted at every step.

How does international shipping work?

UK, US, Switzerland, Canada, Australia, New Zealand, UAE: tax-inclusive prices and any customs duties settled at checkout - nothing extra on delivery.

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.
