What We Do in ACA Meetings. 1  We share what is happening in our lives, and how we are dealing with these issues in our recovery program. 2  We build a personal support network. 3  We practice our recovery and personal boundaries by giving service.
A muffler is an important component of an engine's exhaust system. The muffler is found near the back of a vehicle, and its purpose is to reduce the noise produced from the exhaust process.
Although it may look like a smaller version of a muffler, resonators are designed to be supplemented into an exhaust system to further tune the sound and not replace a muffler completely. A resonator further dampens the sound but more importantly, it is there to alleviate what is known as âexhaust droneâ. Usually during cruising speeds, some exhaust set-ups may exhibit a background buzz that may be heard even inside the passenger compartment.
