What is Marine Exhaust?

A CORSA Performance Marine exhaust system consists of three major components:

Diverters - A diverter splits the exhaust into two exit paths: straight out the hull and down through the propeller. CORSA offers two styles of diverters: a permanently open diverter and a solenoid operated Captain's Call diverter that offers the choice of thru-hull, or a through prop exhaust exits at the flip of a switch.

Silencers - Available as in-line, equalizer (with a balance tube), or silencer tip. Silencer tips are transom mounted outside boat.

Exhaust Tips - Available in a variety of styles including angle-cut, rolled-edge and side exit. See catalog for more details. A majority of exhaust tips include anti-surge valves.

For several reasons including:

1 - Increased performance, faster acceleration, and higher top speed.

2 - A performance look and sound.

3 - When you want it to meet local sound laws - sound reduction without loss of performance.

4 - Premium quality high-grade stainless steel exhaust system design and construction backed by a 3-year warranty.

Performance Gains

Performance gains vary from boat to boat. We have seen top speed increase about 2-3 MPH, which means around a 20 to 30 HP gain. Boats with smaller engines (under 350 cu. In.) will not see much improvement in top speed.

No. The specific CORSA silencers and tips are based on the size and type of your engine, so it will not reduce horsepower, yet it will provide the sound reduction that you need.

Sound Reduction

Typically you can expect a 4-8dB reduction, which is a substantial reduction in sound! CORSA Performance Marine muffler systems achieve this level while still maintaining the desirable exhaust note that boaters love, only with reduced volume to comply with the law and no reduction in performance.

Fitment

Most likely we do. We also custom build exhaust systems offering a variety of designs and styled exhaust tips for most boats. All that is required are a few dimensions from you to design and build a system for your boat.

CORSA Performance Marine has worked closely with Mercury and Volvo along with boat manufacturers to ensure our exhaust systems can be adapted in most cases.

All CORSA Performance Marine exhaust systems are made from 316L premium grade stainless steel that is far more corrosion-resistant than ordinary stainless steels. CORSA Performance Marine components are available in a mirror polish finish, and some components are available in black powder coat.
