Gibson Marine Turn Down Slash-Cut Tip (Pair) - 4in Inlet/11in Length - Stainless

If you're looking to quiet down a high-horsepower marine engine, especially one pushing 500HP and up, these Gibson Marine Turn Down Slash-Cut Tips are a solid option. Designed specifically for large displacement motors, they've been tested on setups up to 1200HP with minimal power loss, meaning you can meet strict sound regulations without sacrificing performance.

These tips are constructed from high-quality stainless steel, which holds up well in the marine environment. The unique design utilizes water to help dampen sound, and they've been proven to meet or even surpass the 88db limit required by California's SAE J2005 Motorboat Sound Law. Installation is straightforward thanks to the clamp-on design, so you won't need extensive modifications to get them fitted.

This pair of tips is sold as a set and includes everything you need for a clamp-on installation. They are designed to fit a 4-inch exhaust inlet and measure 11 inches in overall length, with a slash-cut turndown style that directs exhaust gases downward.
