Custom Marine, Incorporated (CMI) has announced the introduction of a new custom exhaust package specifically designed to enhance the overall performance of any sport boat equipped with a propulsion system powered by a 496 engine. Equipping an engine with the exclusive CMI stainless steel 496 Sport Tube™ Performance Package is sure to attract attention at any dock. But it’s on the water where this package will really turn heads. Simply adding this package to any stock 496 will result in adding nearly 60 more horsepower, boost mid-range torque by nearly 14 percent, boost fuel economy across the power curve and improve the engine’s overall running quality.
“With the introduction of the 496 Sport Tube Performance Package CMI can address the needs of a very key segment of the performance boating marketplace,” said Joe Zelinski, founder and president of CMI. “Until now, installing headers on a 496 package required having a machine and parts shop close by to create the necessary components required to make room for headers. With the CMI 496 Sport Tube Performance Package, performance enthusiasts can simply order our complete, easy-to-install kit.”
The CMI 496 Sport Tube Performance Package comes complete with a pair of water-cooled headers made of 316-series polished stainless steel and required mounting hardware. Also included is CMI’s exclusive 496 Relocation Kit, which includes all brackets, hoses and hardware needed to make relocation of select engine components easier and create adequate room for CMI’s high-tech tube-style headers. Stock CMI tailpipes designed to fit a transom hole layout that is consistent with a standard Mercrusier® Bravo Drive transom hole pattern completes the 496 Sport Tube Performance Package.
The CMI 496 Sport Tube Performance Package is designed for application on all 496 engines.
