They are not MOT compliant and cannot be used on public roads. These components are intended solely for race and track use.

For vehicles manufactured before 1st March 2001, a non-type approved sports catalytic converter may be fitted, provided it offers comparable performance to the original and the vehicle continues to meet the applicable emissions standards for its age. The vehicle must still pass an MOT test.

If you are located outside the UK, please check your local laws and regulations to ensure compliance.

About All Silencers / Mufflers

Standard Exhaust Systems – Engineered for Performance, Sound & Longevity

A standard exhaust system is essential for your Porsche’s performance, efficiency, and sound. It controls the flow of exhaust gases from the engine, reduces emissions, manages noise levels, and ensures balanced back pressure for optimal power delivery.

At Design911, we supply standard exhaust systems built from high-grade stainless steel and corrosion-resistant materials. Designed to meet or exceed manufacturer performance standards, these systems deliver the perfect blend of durability, refinement, and performance — ideal for both daily driving and restoration projects.

Each exhaust system is developed to ensure precise fitment, excellent gas flow, and an authentic Porsche exhaust note that retains the car’s original character.

What Do Standard Exhaust Systems Do?

A standard exhaust system performs several vital roles that keep your Porsche running efficiently, cleanly, and safely.

Core Functions:

  • Directs exhaust gases safely away from the engine.
  • Reduces emissions through catalytic converters and silencers.
  • Controls back pressure for balanced performance and fuel efficiency.
  • Minimises engine noise while preserving Porsche’s signature tone.
  • Aids temperature regulation and exhaust scavenging.

A properly maintained exhaust system ensures smooth performance, reduced fuel consumption, and compliance with emissions regulations.

Why Do Exhaust Systems Fail?

Exhaust systems are constantly exposed to heat, moisture, and corrosive gases — all of which take a toll over time.

Common Causes of Failure Include:

  • Corrosion and rust from road salt, condensation, and moisture.
  • Cracked welds or pipes due to vibration and thermal cycling.
  • Internal baffle damage causing rattling or loss of silencing effect.
  • Blocked or leaking joints leading to reduced performance and increased noise.
  • Burnt-out catalytic converters or mufflers reducing efficiency.

Signs of exhaust failure include loud noises, rattling, exhaust odours, or reduced engine performance — all clear indicators that replacement is required.

Why Replace Standard Exhaust Components?

Replacing a worn or damaged exhaust system restores performance, comfort, and efficiency while maintaining your Porsche’s distinctive exhaust tone.

Key Benefits:

  • Restores proper exhaust flow and back pressure.
  • Improves fuel efficiency and power output.
  • Reduces noise and vibration.
  • Ensures emissions compliance and MOT readiness.
  • Built from corrosion-resistant stainless steel for longevity.
  • Direct-fit compatibility for classic and modern Porsche models.

Upgrading to a high-quality standard exhaust preserves the car’s original performance characteristics while ensuring long-lasting reliability.

Highlights:

  • Precision-engineered exhaust systems for Porsche vehicles.
  • Optimised gas flow for power, torque, and efficiency.
  • Durable stainless-steel construction for corrosion resistance.
  • Designed for authentic tone and perfect fitment.
  • Suitable for classic restoration and modern maintenance.
  • Reliable, quiet, and performance-balanced solutions.
