Muffler & Exhaust Repair Service Video

The muffler quiets combustion gases on their way out, using chambers and baffles to cancel the pressure pulses from each cylinder. Pipes, clamps, and rubber hangers hold it in place under the vehicle.

This video shows where a typical exhaust corrodes first and what a healthy weld looks like next to a rusted-through section. It also shows how leaks you cannot always hear are tracked down.

A deep rumble or rasp that grows under acceleration usually points to a hole ahead of the muffler. A rattle at idle that fades at higher RPM is often a loose heat shield or a broken baffle inside the muffler. An exhaust smell inside the cabin is more serious and needs attention before regular driving.

An inspection traces the system end to end on a lift, marking every corrosion point, cracked hanger, and suspect joint. Depending on the damage, a section is welded in, the muffler is replaced, or a sagging pipe is rehung. When the muffler itself has failed, our muffler repair service explains the full process.

Salted winter roads around Moses Lake and the rest of Grant County leave moisture sitting in the low spots of the exhaust. Condensation inside the muffler adds to it on short trips, rusting the case from the inside out.
