Switchable Exhaust

How Ours Work

When DC current is applied, a magnetic field is generated within the solenoid by passing electrical current through a coil of copper wire and the plunger is drawn in. When DC current is removed, the magnetic field is released and a return spring (not shown) pushes the plunger to an open position. The force generated by a solenoid is dependent upon the current flowing though the coil windings. Solenoids draw a very high amperage or current for a split second while pulling the plunger into the coil, then a switch or control module significantly reduces amperage while in the holding mode or the closed position.

CORSA Performance Marine takes pride in delivering a quality product that provides years of trouble free operation to you and your customers. In 2003 as a part of CORSA Performance Marine's continuous improvement efforts, we changed from an external electromechanical relay to a more reliable control module with an internal solid state relay. This change resulted in a reduction in both customer complaints and warranty claims.

Solid State Relay Systems vs. Pneumatic Systems


There are major differences between pneumatic and solid state systems. To determine the advantages of each type, the following characteristics should be examined: RELIABILITY, DESIGN PACKAGE DIMENSIONS, ANDRESPONSIVENESS.


Both types of technology exhibit similar levels of reliability during initial operation, over an extended period of time the solid state relay is more reliable due to its longer service life and minimal moving components.


The control module's internal circuitry and solid state relay are designed specifically for solenoid control. The control module circuitry is hard wired to the solenoid, reducing the number of mechanical wire connections, which eliminates the potential for failure due to corrosion at these connections. To further ensure corrosion protection, the control module is contained in a hermetically sealed unit.


The Pneumatic concept has been around for years with no technology. A bulky compressor with multiple feed lines that run a linear actuator. With the weight of the compressor, limited quick use and potential failure points, the design of a pneumatic system does not keep the needs of the customer in mind.


CORSA Performance Marine's sleek design means no external pumps or control units, the components are attached directly to the diverter.The space saving design is possible because solid state relays only house small semiconductor components.


Pneumatic systems require a standalone compressor that feeds and controls the diverter. With a much larger area needed to mount and run multiple lines from the compressor needed, Installations are not always permitted.


A solid state relayed system exhibits a quick response rate; with a flick of a switch you have controlled the tone of your exhaust.


A Pneumatic system relies on a compressor to generate air to then actuate the exhaust to change the tone of your exhaust. Pneumatic systems have an overall limited quick use.
