RACETRACK USE ONLY:

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.

The kit includes the right and left-hand mufflers without valve. It can be assembled on the OE central silencer, or in combination with the Tubi Style central silencer.
The component is perfectly interchangeable with the original components, following the instructions in the constructor's workshop manual.

EXHAUST VALVE: NO VALVE

The exhaust system does not include a valve and always guarantees the most impressive sound. If the standard system includes one, control of the exhaust valve by both the engine ECU and by the driver via the specific control systems is no longer possible.

The muffler must be used in conjunction with the original exhaust end tips.

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

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.

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
