Exhaust Cut-Out Hook-Up 2.5in Kit

The Patriot Exhaust Exhaust Cut-Out Hook-Up 2.5in Kit provides marine operators and performance boaters with an effective manual control solution for dual exhaust systems. Whether you're running an inboard or outboard high-performance setup, this clamp-on cutout allows you to bypass your muffler system on demand—a feature that serious water enthusiasts have relied on for decades to gain responsive engine acoustics and slight performance gains during full throttle runs. Built for 2.5-inch pipe diameter exhausts, this kit ships complete with blockoff plates and all hardware needed for installation, eliminating trips to the marine supply store.

Constructed from steel and finished with zinc plating, the Exhaust Cut-Out Hook-Up 2.5in Kit resists saltwater corrosion and the harsh UV exposure inherent to marine environments. The manual clamp-on design means no electrical components or complex wiring—just straightforward mechanical operation with a simple lever or cable pull to activate the cutout. The kit's dual-exhaust configuration accommodates both sides of your system simultaneously, ensuring balanced flow and even exhaust note. The included blockoff plates seal the muffler inlet when the cutout is engaged, preventing backpressure loss and maintaining engine efficiency during normal cruising.

This exhaust cutout is ideal for performance boat owners, marine mechanics, and DIY installers who want straightforward control over their dual exhaust tone without aftermarket tuning or ECU modifications. The 11.1 x 5.4 x 13.5-inch package fits neatly in engine compartments typical of mid-to-large displacement marine powerplants. Installation requires basic hand tools and familiarity with clamp work; most boaters complete the job in under an hour. Compatible with any marine engine featuring a 2.5-inch dual-exhaust system, this kit delivers lasting performance and everyday reliability on the water.
