Pneumatic Exhaust Valves 70 mm (2.75 Inch) for Active and Performance Exhaust Systems

Pneumatic Exhaust Valves 70 mm (2.75") for Tuning and Motorsport

Our high-performance pneumatic exhaust valves 70 mm (2.75") are engineered for active exhaust systems, custom tuning builds and motorsport applications. Using a vacuum-actuated mechanism, these valves provide seamless control over exhaust flow and sound, allowing drivers to switch instantly between quiet operation and aggressive, straight-pipe performance.

The 70 mm (2.75 inch) size is ideal for mid-size exhaust setups used in turbocharged, supercharged and naturally aspirated engines where balancing backpressure and optimizing exhaust flow are essential for maximum performance.

Why Choose 70 mm Pneumatic Exhaust Valves?

Our pneumatic exhaust valves are designed to deliver smooth actuation, precision and durability in all conditions. Here’s why the 70 mm size is a perfect fit for tuning enthusiasts:

• Optimized for 70 mm / 2.75-inch systems – perfect for mid-size performance exhausts
• Vacuum-actuated operation – smooth, reliable and highly responsive
• Active exhaust functionality – switch between quiet and aggressive sound instantly
• Enhanced power – bypass mufflers to maximize exhaust flow when needed
• Universal compatibility – works with turbocharged, supercharged and NA engines

How Pneumatic Exhaust Valves Work

Our pneumatic exhaust valves use a vacuum-controlled actuator connected to the engine’s vacuum system or an auxiliary pump. When vacuum is applied, the valve opens, allowing gases to bypass mufflers and restrictions. When closed, exhaust gases flow through the muffler, reducing sound levels and maintaining comfort. This design offers a straight-pipe effect on demand while preserving daily drivability.
