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.

The ultimate Sports Exhaust system for the Porsche GT3 inc RS & CS
QuickSilver were approached by a well known specialist in racing and track-day Porsche, to develop a complete SUPERCUP exhaust system for enthusiast customers.

KEY FEATURES:
• More Power +20bhp
• Less Weight - to lose over 20kgs (~44lbs) from the rear of the car.
• Ease of fit & no loss of ground clearance > All in a compact volume.
• Great Sound - but to enable compliance with most track-day venues - A tall order!
• Motorsports Look.
• Appropriate Sound - about 105dB > but reduced further with removable Titanium cans.

An ambitious project, requiring new materials technology, manufacturing methods, component integration and constant testing.

The factory exhaust includes five muffler casings, 2 x Cats, 2 x side mufflers and 1 x rear muffler. QuickSilver's brief was to distil these into 1 x casing & similar to the system produced by Porsche's Motorsport Dept for their international one-make racing series.

Drawing their constant racing experience our partners were able to provide technical input and testing facilities.

Throughout the development period the system was evaluated both at our partner's in-house test facilities and on the track. Each time refinements were included in the overall design to create a fantastic system worthy of the Porsche name.

QuickSilver system includes:
• Manifolds with equal-lenght primary pipes of the appropriate bore for optimum power.
• Single rear silencer casing housing integral 200 cpsi RACE catalytic converters.
• Provision for fitting of OBD2 exhaust sensors measuring the exhaust gas composition before and after the Cats on both cylinder banks.

Brand: QUICK SILVER

About Exhaust Package

Exhaust System Packages for Porsche | Performance, Precision & Sound

A well-designed exhaust system package is essential for maintaining your Porsche’s performance, efficiency, and distinctive exhaust tone. These complete systems replace worn or restrictive exhaust components with precision-engineered, high-flow assemblies that restore or enhance power delivery and sound quality.

At Design911, we offer a comprehensive selection of exhaust system packages for Porsche models — from classic 911s to modern GT-series vehicles. Each package includes key components such as silencers, manifolds, catalytic converters, and pipework, designed for optimal gas flow, reduced back pressure, and improved throttle response.

Manufactured from premium stainless steel, Inconel, or titanium, our exhaust kits are built for durability, corrosion resistance, and superior acoustic performance. Whether you’re restoring a vintage air-cooled model or tuning your track-ready GT3, these exhaust systems deliver a perfect balance of reliability, performance, and sound.

What Do Exhaust System Packages Do?

An exhaust system package channels exhaust gases away from the engine efficiently while controlling noise and emissions. A properly designed system ensures optimal engine breathing — improving power, torque, and overall efficiency.

Core Functions:

  • Directs exhaust gases safely from the engine.
  • Reduces back pressure to maximise power output.
  • Controls emissions via catalytic converters and mufflers.
  • Enhances exhaust tone for an authentic Porsche sound.
  • Optimises gas flow for performance and reliability.

An upgraded exhaust system can also provide weight reduction, improved throttle response, and enhanced driving enjoyment.

Why Do Exhaust Systems Fail?

Over time, even the most durable exhaust systems deteriorate due to constant exposure to heat, vibration, and the elements.

Common Causes of Exhaust System Failure Include:
Corrosion and rust, especially on mild steel systems.

  • Cracks or leaks caused by vibration and thermal stress.
  • Worn gaskets or clamps leading to exhaust leaks.
  • Clogged catalytic converters reducing flow and performance.
  • Broken hangers or mounts causing misalignment.

When exhaust components fail, you may notice rattling sounds, loss of performance, strong fumes, or increased fuel consumption — all signs that replacement is needed.

Why Replace or Upgrade Your Exhaust System?

Replacing or upgrading your Porsche’s exhaust system ensures maximum performance, efficiency, and driving enjoyment.

Key Benefits:

  • Restores optimal gas flow and back pressure.
  • Improves horsepower and torque.
  • Enhances sound and throttle response.
  • Reduces weight for improved handling.
  • Prevents leaks and emissions issues.
  • Crafted from corrosion-resistant, high-grade materials.
  • Direct-fit design for Porsche 911, Cayman, Boxster, Panamera, Macan and more.

Whether for performance tuning, restoration, or replacement, Design911’s exhaust system packages deliver the sound, precision, and reliability Porsche owners expect.

Highlights:

  • Complete exhaust system packages for all Porsche models.
  • Includes manifolds, silencers, catalytic converters, and pipes.
  • Manufactured from stainless steel, Inconel, or titanium.
  • Engineered for maximum performance and sound.
  • Precision-fit designs for simple installation.
  • Ideal for performance upgrades or restorations.
