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.

Key Features & Benefits:

  • Complete system, including 2× stainless steel GT manifolds (ID 42 mm primaries with flared collector boxes),high-flow catalytic converter set or straight through link pipes and sport rear silencer — all configured for RH tailpipe exit, no exhaust valves. 
  • Made entirely from lightweight, high-quality SS304L stainless steel for durability, corrosion resistance, and long-term reliability — ideal for spirited driving or restoration builds. 
  • Designed for “TÜV” compliance (option with catalysts), while delivering a more aggressive exhaust note, improved throttle response, freer revving and performance gains compared to stock exhaust. cargraphic.de Reduced back-pressure and optimized flow — leads to smoother engine breathing, potential gains in horsepower/torque, more immediate throttle response and enhanced driving dynamics. 
  • Upgraded mounting hardware, mandrel-bent pipes and optimized geometry ensure correct fitment, easy installation (with included gaskets, clamps, brackets), and good clearance to engine components. 
  • Lightweight construction also contributes to modest weight savings compared to stock exhaust components — beneficial for handling and responsive driving. 

Why Choose This Exhaust System?
The original exhaust on older 964 models can be restrictive in flow, heavy, and produce a muted sound. Switching to this CARGRAPHIC system unlocks the engine’s full potential: better exhaust flow, sharper throttle response, more pronounced exhaust tone, and improved performance — all while retaining reliability and proper fitment. It’s an ideal upgrade for enthusiasts seeking classic 964 sound and performance without resorting to race-only systems.

About Sport Silencers / Mufflers

Porsche Sport Silencers & Mufflers - Performance Sound & Exhaust Upgrades

Sport Silencers / Mufflers are designed to enhance the sound, performance, and driving character of your Porsche by improving exhaust gas flow and delivering a more engaging exhaust note. Compared to standard exhaust silencers, sports mufflers reduce restriction, sharpen throttle response, and provide a sportier tone that better reflects Porsche’s performance heritage.

Available from Design911, this category includes both genuine Porsche sport exhaust components and high-quality aftermarket performance mufflers, giving owners the choice between factory-engineered authenticity and performance-focused customisation.

What Do Sport Silencers / Mufflers Do?

Sport silencers optimise exhaust flow while enhancing sound quality.

Core Functions:

  • Reduce exhaust backpressure for improved engine breathing.
  • Enhance throttle response and power delivery.
  • Produce a deeper, sportier exhaust note.
  • Improve exhaust efficiency and flow dynamics.
  • Enhance the overall driving experience.

A well-designed sports muffler balances performance gains with refined sound control.

Why Do Standard Exhaust Silencers Fail or Fall Short?

Standard exhaust mufflers are designed primarily for noise reduction, emissions compliance, and longevity. Over time, common issues include:

  • Internal corrosion from condensation and heat cycles.
  • Restrictive baffling limiting exhaust flow.
  • Dull or muted exhaust sound.
  • Internal baffle breakdown causing rattles.
  • Reduced efficiency when paired with performance upgrades.

As these components age, both performance and sound quality can deteriorate.

Why Upgrade to Sport Silencers / Mufflers?

Sport silencers are engineered to improve both performance and auditory feedback.

Upgrade Benefits:

  • Improved exhaust flow and reduced restriction.
  • Enhanced exhaust sound without excessive drone.
  • Increased driving engagement and responsiveness.
  • Available in OEM Porsche or performance aftermarket options.
  • Ideal for road, touring, and spirited driving.

Upgrading delivers a more exciting exhaust character while supporting engine efficiency.

Highlights

  • Porsche sport silencer and muffler upgrades
  • OEM Porsche and premium aftermarket options
  • Improved exhaust sound, flow, and performance
  • Designed for performance-focused driving
  • High-quality materials for durability and reliability
