SOUND: If you're looking for a really aggressive exhaust note and you're not worried about waking up the neighbors, this is the system for you! This exhaust will deliver ripping sports car sound, at the cost of some interior drone. The Supercup is significantly louder than our Maxflo Exhaust, but If you want the best of both worlds, check out our TrackTec Valved Exhaust, which will be slightly louder than the Supercup with the valves open and just as civilized as our Maxflo system with the valves closed.
POWER: By dyno designing this system specifically for the Porsche 981 Boxster/Cayman platform, we've been able to squeeze the most horsepower possible. Our dyno testing showed an increase of 15 whp and 19 ft-lbs of tq at 4000 RPM. Peak gains are 11 whp and 11 ft-lbs of tq.
FEATURES:
• Fits all Porsche 981 Boxster/Cayman vehicles (2013-2016)
• Includes deluxe dual style tips in your choice of satin black, carbon fiber, or Polished Stainless Steel
• Improves power by 15 whp and 19 ft-lbs of tq
• Complies with all U.S. emissions regulations
• Saves 15 lbs from the rear of the vehicle compared to the full OEM exhaust system
• Straight through design uses two 2.25" resonators to minimize weight and improve top-end performance
• Constructed from high quality 14-16ga CNC mandrel-bent T304 stainless steel for maximum performance and durability
• Noticeable improvement in sports car sound and throttle response
• Bolt-on with no cutting or welding required
• All Fabspeed performance products are backed by the Fabspeed Lifetime Warranty

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.
