Quiet that telltale exhaust leak and get back to smooth, confident driving. This high-heat muffler cement is designed specifically for sealing seams, pinholes, and small gaps in mufflers, tailpipes, and exhaust connection points. It applies as a thick paste and cures to a cement-like hardness for durable, long-lasting repairs.
Engineered for the heat and vibration of exhaust systems, the formula withstands temperatures up to 850°F when fully cured. A 2–4 hour set time lets you position clamps or hardware, while a full 24-hour cure delivers maximum strength and stability. The cured color is dark gray to blend cleanly with typical exhaust components.
This metal-containing, sodium silicate–based paste bonds to clean automotive metal surfaces, helping stop noise and prevent exhaust leaks at slip joints, flanges, and welded seams. It’s an ideal fix for worn joints or small corrosion spots where replacement isn’t immediately practical.
Whether you wrench on a daily driver or keep a cherished weekend cruiser on the road, this repair cement helps you take pride in doing it yourself—saving time, money, and the next drive with confidence.
