High quality exhaust system for the Porsche 996 Turbo. Manifold back exhaust that includes 200 Cell Sports Cats and does not include tailpipes or manifolds.
The silencers in this exhaust are linked to one another, creating a greater balance between the two silencers which improves flow, performance and provides a sports sound. It is an aftermarket, performance exhaust with a louder note and boasts significant power gains over OE due to a free-flowing, mandrel bent, TIG welded system. The cats are about as powerful as we could get onto the Porsche 911 Turbo while still passing the MOT!

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
