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
