Fits
Porsche 911 turbo 997 Gen 2
Porsche 911 turbo S 997 Gen 2

The component is perfectly interchangeable with the original components, following the instructions in the constructor's workshop manual

RACETRACK USE ONLY
These components are designed and developed for racetrack use and to maximise the car's performance. They are not street legal and must be installed by professionals in the sector

CATALYTIC CONVERTER REMOVAL
This reduces exhaust back pressure while still maintaining the operation of the catalytic converter, and improves performance and sound

ECU REMAPPING - FOR PERFORMANCE
On turbo cars, catalytic converter replacement may modify turbocharger operating conditions and cause a deterioration of the torque delivery curve. To ensure full benefit from the new racing component, the engine's ECU must be reprogrammed to maximise performance. If the engine warning light comes on, the ECU must always be reprogrammed to eliminate it

SOUND - TUBI SOUND
Tubi Sound is the standard sound of Tubi Style exhausts, louder and more powerful than the original sound. This sound represents our brand

END TIPS DESIGN - OE
The muffler must be used in conjunction with the original exhaust end tips

END TIPS NUMBER AND POSITION - 1 + 1 AT THE SIDES
The tailpipes are located low down at the sides of the car. There is one tailpipe at each side

MATERIAL - AISI 304 STAINLESS STEEL
A choice stainless steel ideal for aggressive environments where combustion emissions can cause serious chemical corrosion on other types of metal

EXHAUST FINISH - POLISHED
Mirror finishes are highly reflective and created by polishing the stainless steel. The polishing process enhances appearance and consistency, making cleaning easier. A special rolling procedure is used. It is essential to remove deep scratches as any surface defects will be very noticeable on the finished product. it improves corrosion resistance. The polishing eradicates crevices where corrosive particles can lodge themselves.

MAIN PIPE DIMENSION 65mm
This is the diameter of the main pipe of the exhaust system

Please note: sports catalytic converters or bypass pipes do have type approval and may not be legally installed on vehicles manufactured after 1st March 2001. They can not be used on a public road and are not MOT compliant, they are designed for race and track cars only.

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
