An unavoidable [[side effect]] of muffler use is an increase of [[back pressure]] which decreases [[engine efficiency]]. This is because the engine exhaust must share the same complex exit pathway built inside the muffler as the sound pressure that the muffler is designed to mitigate.
 
Some vehicle owners remove or install an [[Aftermarket (automotive)|aftermarket]] muffler when [[engine tuning]] in order to increase [[Power (physics)|power]] output or reduce [[Fuel economy in automobiles|fuel consumption]] because of [[economic]] or [[Environmental quality|environmental]] concerns, recreational pursuits such as [[motorsport]] and [[hypermiling]] and/or for personal [[Aesthetics|aesthetic]] [[Acoustics|acoustical]] preferences. Although the [[Law|legality]] of altering a motor vehicle's [[Original equipment manufacturer|OEM]] exhaust system varies by jurisdiction, in most [[Developed country|developed parts of the world]], modification of a vehicle's exhaust system is usually highly regulated if not strictly prohibited.
