Fits:
Porsche 987.1 Boxster / Boxster S - 2005 to 2008
Porsche 987.1 Cayman / Cayman S - 2005 to 2008

Ideal for enthusiasts seeking a more conservative sound enhancement, this muffler is particularly suited for those running cat bypass or sport cats who want to avoid excessive noise levels. At low RPMs and during cruising, it delivers a refined, deep tone that remains discreet. Designed to comply with Germany's stringent urban decibel regulations, this is a German Edition muffler built for subtle performance.

DesignTek offers a wide selection of mufflers to suit diverse preferences, ranging from mild, street-friendly options to exotic-sounding sport mufflers and high-intensity race mufflers. The DesignTEk Edition 987.1 street muffler stands apart from conventional aftermarket designs.

Crafted from German V2A - X5CrNi18-10 - 1.4301 (T-304 L) lightweight stainless steel, it incorporates advanced features like double perforated sound absorption tubes in a trapezoidal pattern with variable perforation diameters. This design effectively isolates and dampens unwanted drone frequencies. Additional stamped ribbing on the outer shell further reduces unwanted resonance, achieving superior acoustic performance.
Unlike traditional baffle plates, this design minimizes back pressure, particularly at higher gas velocities, resulting in improved throttle response and enhanced performance across the rev range. When combined with software tuning, upgraded intakes, or additional exhaust modifications, the benefits are even more pronounced.

This muffler offers a subtle factory motorsport sound, making it an excellent choice for those who desire a conservative sport tone. Its reduced decibel output ensures it remains suitable for vehicles equipped with sport cat or cat bypass headers, maintaining an enjoyable sound without becoming overly loud.

Each system undergoes rigorous testing for exhaust gas flow, thermal durability, resistance to cracking, and long-term reliability, ensuring exceptional quality and performance.

Features:

  • Increases by 9 HP and 11 TQ
  • Weighs 43 lbs. (19.5 Kg)
  • German V2A - X5CrNi18-10 - 1.4301 (T-304 L) stainless steel for improved durability
  • Includes dual round 3.5” (90mm) tips
  • Direct bolt on replacement
  • Increased decibels with an exclusive, exotic motorsport sound
  • Software programming is not necessary

Fabspeed Supercup Race Exhaust System

Fabspeed Supercup Exhaust System is a loud and aggressive performance exhaust system designed with track use in mind. This system is a lot lighter than the factory system and flows much better. The Supercup is significantly louder than our Maxflo Exhaust option, but if you're looking for a very aggressive exhaust note and you're not worried about waking up the neighbors, this is the system for you! 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

FEATURES:

Fits all Porsche 987 Boxster/Cayman vehicles (2005-2008)
• Includes Deluxe Quad Style Tips in your choice of finish - Choose between Polished or Satin Black
• Increase horsepower and torque by 10 whp and 8 ft-lbs
• Saves 18lbs from the rear of the vehicle
• Complies with emissions regulations
• Includes two resonators to minimize weight and improve top end power.
• Constructed from high quality 14-16ga CNC mandrel-bent T304 stainless steel for maximum performance and durability
• Direct replacement for the OEM muffler with no cutting or welding required
• All Fabspeed performance products are backed by the Fabspeed Lifetime Warranty

Please note: This is a special-order item manufactured to order. In some cases, please allow 4 – 5 weeks for the delivery. Special order items cannot be cancelled from this supplier once your order has been placed.

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
Complete removal of the catalytic converter minimises exhaust back pressure and delivers optimum results in terms of performance and weight reduction

ECU REMAPPING - ENGINE LIGHT
Replacement or removal of components such as catalytic converters and electric actuators may cause the engine warning light to come on. In this case, the installer must reprogram the software to eliminate the light

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

MATERIAL - AISI 304 STAINLESS STEEL
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

MAIN PIPE DIMENSION - 57mm
This is the diameter of the main pipe of the exhaust system

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 valve by both the engine ECU and by the pilot via the specific control systems is no longer possible

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
