How do I Replace the Muffler on a 1997 Honda Accord EX Coupe?
- 1). Park the Accord on a flat, level surface and set the parking brake.
- 2). Position the jack under the rear of the vehicle, in the center of the frame. Lift the car and place jack stands under both axles.
- 3). Cut the pipe from the muffler to the catalytic converter with a hacksaw. Make the cut about 1 1/2 inches from the muffler. If the pipe is held on with pipe clamps, remove the bolts holding the pipe clamps in place with a socket wrench. When they are sufficiently loosened, slide the pipe clamps onto the pipe close to the catalytic converter.
- 4). Spray the bolts holding the muffler hanger with penetrating lubricant. The muffler gets wet from being exposed, and the bolts have a tendency to rust shut. Let the lubricant soak in, then remove the bolts with a socket wrench.
- 5). Remove the muffler from the muffler hangers. Handle the muffler carefully as it can be heavy.
- 6). Place the new muffler in the wire hangers and tighten them down most of the way with a socket wrench. Leave a little bit of slack so the muffler can be positioned against the catalytic converter.
- 7). Weld the muffler to the catalytic converter pipe. Make sure the weld is strong because the muffler will have to handle a lot of stress.
- 8). Tighten the muffler hanger bolts completely. Remove the jack stands and lower the Accord.
