Cen-Cal Motorsport F1 Exhaust System – Porsche 991.1 /991.2 GT3 & GT3RS

Cen-Cal Motorsport F1 Exhaust System – Porsche 991.1 / 991.2 GT3 & GT3RS

The legendary 9,000 RPM flat-six of the Porsche GT3 and GT3 RS deserves to be heard the way Porsche motorsport intended—and the Cen-Cal Motorsport F1 Exhaust System delivers that symphony in its purest, most exhilarating form. Developed for the 991.1 and 991.2 GT3 / GT3RS platforms, this system transforms your driving experience with a razor-sharp, F1-inspired tone that builds intensity all the way to redline.

After extensive R&D and acoustic testing, our system brings out the aggressive, high-frequency pitch reminiscent of Porsche’s factory RSR race cars—without compromising drivability or quality. Whether you prefer full race sound or a controllable, street-friendly setup, this system adapts perfectly to your needs.

Precision-Engineered Design

Meticulously built using mandrel-bent piping and TIG-welded craftsmanship, the F1 system ensures unrestricted flow, maximum durability, and consistent performance under the harshest track or street conditions.

F1-Inspired X-Pipe Configuration

A large cross-section X-pipe with looped piping geometry creates that signature high-pitched, motorsport-style scream—balancing tone, resonance, and exhaust velocity for an authentic race car experience.

Material Options

• Brushed T304 Stainless Steel – Premium strength, durability, and value.

• Grade 5 Ti 6Al-4V Titanium – Extreme weight savings, exotic sound characteristics, and unmatched corrosion resistance.

Configuration Options

• Valved Catback (Street Version): Features vacuum-actuated valves that bypass the mufflers when open for a ferocious tone, and route through the mufflers when closed for a refined, quiet cruise.

• Non-Valved “Crack Pipe” Catback (Race Version): Always open, always loud—pure F1 pitch for the most aggressive sound possible.

• Header Options:

  • Free-Flow Catless Race Headers for maximum sound and performance.

  • High-Flow Catted Race Headers for a more balanced street setup.

  • Stock Header Compatibility for those who wish to retain factory manifolds.
