A Sound Decision
With many boating areas enacting 90 dB (at idle) noise laws, chances are your full-time,thru-hull open exhaust system will not pass local noise law requirements. CORSA Performance offers three versions of state-of-the-art, legally muffled, thru-hull high performance exhaust systems available for most engine applications, including Mercury High Performance. With CORSA’s unique sound dampening systems you can meet legal sound emissions laws in most areas, and still enjoy the performance benefits of thru-hull systems in unrestricted areas.

All CORSA exhaust systems are made from 100% high-grade 316L stainless steel with our patented noise reduction technology. Each system is backed by a 3-year limited warranty.

Quick & Quiet Systems

Full Time Legal Exhaust Systems

QUICK & QUIET™ CORSA’s non-restrictive mufflers and silencers were developed for boats equipped with thru-hull, full-time open exhaust systems. They are the ideal solution for removing the harsh noise while retaining a distinctive rumble and maximum performance. Quick & Quiet™ systems include two patented transom-mounted ASR Silencer Tips and two ASR interior mufflers with a balance tube and are designed to retrofit existing full-time, thru-hull applications.

Electric Captain’s Call
Diverter Systems

With CORSA’s Captain’s Call™ Diverter Systems you can enjoy the open water sound and performance of an open thru-hull exhaust system and still be a quiet neighbor in the marina. Exhaust flow can be routed through the transom for open water running or through the prop with the simple flip of a helm-mounted switch.

CORSA designs exhaust systems for all major boat manufacturers’ engines, including the Mercury HP Series (shown left). Diverters are available separately or as a complete system kit with hoses, clamps, wiring and a choice of various styles of exhaust tips.
