This is the ultimate exhaust option that CORSA Performance offers today. When properly configured, it can meet a majority of the sound requirements within the 50 states on stock engines. This system incorporates a Captains Call exhaust that allows you to choose between a bold thru-hull configuration or a quiet thru-prop mode. When the thru-hull mode is selected, the exhaust passes through a silencer which reduces sound levels. This system tames some of the loudest engines without sacrificing any performance. There are many different configurations available, options include: offset, side exit, straight back and transverse. Applications are conveniently offered as kits which include silencer exhaust tips or mufflers, hose, clamps and all of the electronics necessary for the installation. All systems are constructed from a high-grade 316L stainless steel and are available in a highly polished mirror finish as well as a classic gloss black powder coat finish; both are very attractive and highlight any engine compartment.
