Sports Exhaust Muffler DesignTek VALVETRONIC system with 200 SPORTS CELL CATS. + Headers.

High Grade stainless steel equal length headers.K16 Sport stainless steel headers have been designed to increase HP and TQ on cars fitted with the OEM K16 turbochargers. The short design is perfectly matched for the exhaust travel from the heads to the K16 turbo for better boost response and power throughout the rev range. The smooth flow through the mandrel bends and pyramid merge collector offer superior flow characteristics as compared to the OEM headers. Power gains are increased by 14 HP and 16 Ft. TQ with no other modifications.Adds up to 14 HP / 16 Ft. TQ

For the ultimate performance gains we recommend this set is fitted with an ECU remap giving BHP and Torque that you can really feel and superb sports car sound.

NOTE: In the United Kingdom, sports catalytic converters and bypass pipes do not have type approval and are not legally permitted for use on vehicles manufactured after 1st March 2001. 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 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.
