designtek

DesignTek sport exhaust rear boxes are design to give a better throttle response, and also allowing the engine to breather. DesignTek exhaust sounds slightly deeper than the original Porsche standard exhaust. All DesignTek Exhaust Systems are manufactured from 14 - 16 gauge extra heavy duty T304 stainless steel, which eliminates the splitting, cracking and annoying resonance.

Fits:
Porsche 993 1994-97 (not Turbo & GT2)

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
