Exhaust Muffler Replacement near Morristown, New Jersey

Replacement varies with vehicle type. Many factory mufflers only require the rear most section to be unbolted and replaced with new. Because of the location, usage of penetrating chemicals and heat may be required to free the corrosion on the fasteners. If installing an aftermarket muffler with different flanges, cutting and welding of the original exhaust pipe may be necessary to fit the new one.

While the muffler is off for replacement, consider replacing the rubber hangers or "donuts". If these are worn or missing, the muffler will move around unrestricted and cause the junctions to fail even on quality replacements.

With exception to some high-end aftermarket performance systems, the OEM muffler is usually the best one for your vehicle. Having a shop weld on an off the shelf muffler will be cheaper in the short run, but may fail more often depending on the quality of the aftermarket muffler, and the quality of the shop's welding ability.

Replacing a muffler is only a DIY capable project if the existing muffler and replacement muffler can be changed without welding. If welding is required, a professional exhaust welder should complete the repair.
