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.

- 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

The Akrapovič Slip-On Line for the Porsche 911 Turbo / Turbo S is the first stage in the exhaust tuning process and gives this already outstanding car a further step in performance. Made from a high-grade titanium alloy and finished with exquisitely handcrafted carbon fibre and titanium tailpipes, the Slip-On Line reduces weight to aid with handling. Akrapovič's sound engineers have also created a deep and unique sound to make the Porsche 911 Turbo / Turbo S stand out even more. The Slip-On Line can also be used in conjunction with the optional Akrapovič link pipes—with or without cats—which can be added to the system to take the performance to another level. The Slip-On Line is superbly finished with a coating to give greater durability, without altering the look or performance of the system.
