The Gibson Bullet marine clamp-on mufflers (pair) with 4‑in inlet and 11‑in length are designed for large displacement marine engines and were tested up to 1,200 HP with minimal power loss. They use stainless construction, an OEM-style transom mount and a straight-through design that utilizes water to dampen sound. These silencers have been shown to meet California J2005 sound limits while preserving power.
