A muffler is a device to decrease the amount of noise emitted by the exhaust of an internal-combustion engine.
Mufflers are installed within the exhaust system of most vehicles’ engines, although they do not serve any primary exhaust function. They are engineered as an acoustic soundproofing devices designed to reduce the loudness of the engine through acoustic quieting. Most mufflers work by routing the exhaust gases through a series of passages and chambers lined with roving fiberglass insulation and resonating chambers harmonically tuned to create destructive interference which makes sound waves cancel each other out. The unavoidable side effect of muffler use is an increase of back pressure in the exhaust, which decreases engine efficiency and may decrease power.
It is not uncommon for a vehicle owner to remove their muffler or install an aftermarket muffler to increase power output, reduce fuel consumption, or achieve a better exhaust sound if they modify their vehicle. However, modification of a vehicle’s exhaust system is highly regulated and removing your muffler is almost certainly illegal in California. Aftermarket mufflers can break noise or emissions laws and result in a pricey fix-it ticket. It is also possible for your original muffler to develop a leak or defect which can reduce its efficiency and lead to louder than normal sound or higher emissions. Modern cars are tuned to run most efficiently with a fully functioning exhaust system, and removing or modifying it can potentially confuse important sensors and cause unforeseen problems. If you are thinking about removing or modifying your exhaust, you should consider that the performance and efficiency gains will most likely be extremely minor, and you may incur unwanted attention from police and neighbors.
