Parts Desk Insights
Best use case: The Centek Minimax is the go-to choice for V-drive inboard installations and any application where the standard muffler footprint is too large for the available space. Commonly specified on performance boats, ski boats, and custom inboard builds with tight bilge layouts. Confirm that your exhaust routing is above the waterline before ordering — this muffler is not rated for below-waterline or wet exhaust applications. Match hose diameter carefully to the 4" connections; reducing or enlarging hose size will affect back pressure and exhaust flow. If you’re unsure whether this muffler suits your installation, contact us with your engine make, model, and exhaust routing details.
