Product Information
DesignTek Sport Exhaust muffler / silencer rear box, with valves, 1 IN 2 OUT
* tail pipes not included.

The DesignTek 1 IN 2 OUT sports exhaust muffler with valves is a high-performance upgrade designed for classic Porsche 911 models from 1975 to 1989. Combining modern exhaust engineering with classic air-cooled character, this rear silencer enhances both sound and performance while maintaining compatibility with original exhaust layouts.

Fits:
Porsche 911 1975 - 1989

Featuring a twin-outlet (2-out) design, this system delivers a more aggressive and sporty appearance compared to standard single-outlet silencers, while also improving exhaust gas flow. The valve-controlled system allows you to switch between a refined, quieter exhaust tone and a louder, more aggressive sports sound, giving you flexibility for both everyday driving and spirited use.

Performance exhaust systems like this are designed to reduce backpressure and improve airflow, helping the engine breathe more efficiently and potentially improving throttle response. A freer-flowing exhaust also produces a deeper, more pronounced flat-six exhaust note, enhancing the overall driving experience.

Constructed from high-quality materials and engineered to withstand the heat and vibration of air-cooled engines, this DesignTek muffler offers durability alongside performance gains. It is designed as a direct-fit replacement, making it suitable for restoration projects, upgrades, or replacing worn original silencers.
