The exhaust muffler is a component of your exhaust system that quiets the sound from your exhaust. Without it, the sound from an engine can be very loud. It is typically placed toward the back of your exhaust pipe underneath the vehicle in front of the rear axle. Over time, road debris and corrosion can damage your exhaust system. If you notice your car suddenly becomes louder, check underneath your vehicle for a rusty muffler or exhaust pipe. If you notice your muffler is damaged, find a replacement muffler at O'Reilly Auto Parts. We carry all the parts you need to complete your muffler or exhaust repair.
