PRODUCT DESCRIPTION
JRspec Active Muffler with 63mm (2.5") Vacuum Valve Remote Control (Right)
This vacuum valve muffler is an innovative exhaust system component that combines the characteristics of a traditional muffler and a straight-through sport muffler. Thanks to a soundproofing chamber and a pneumatic valve that controls the exhaust flow, the user can adjust the sound to their preferences.
- In the closed position, exhaust gases pass through the soundproofing chamber, which significantly reduces noise, especially at low RPMs.
- In the open position, exhaust gases exit freely, which improves performance and provides the exhaust system with a sporty sound.
The entire structure is made of high-quality 304 stainless steel, resistant to weather, road salt, and chemicals present in exhaust gases. All elements are pressed for increased rigidity and to eliminate vibrations.
Product features:
- Sound regulation: possibility to choose between a quiet or sporty sound.
- Installation using the vehicle's vacuum pump.
- Entirely made of 304 stainless steel.
