We Replace Mufflers With Quality Ones We Can Stand Behind!
High quality mufflers
AutoMetrics is your best source in Yakima for muffler replacement. We install O.E. quality bolt-in mufflers, not offshore weld-in types.
How mufflers work
Mufflers are installed within the exhaust system of most internal combustion engines, although the muffler is not designed to serve any primary exhaust function. The muffler is engineered as an acoustic soundproofing device designed to reduce the volume of the sound pressure created by the engine. The majority of the sound pressure produced by the engine is emanated out of the vehicle using the same piping used by the silent exhaust gases absorbed by a series of passages and chambers lined with roving fiberglass insulation and/or resonating chambers harmonically tuned to cause destructive interference wherein opposite sound waves cancel each other out.
Engine performance and mufflers
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 built to reduce. Performance companies offer louder and less restrictive mufflers to the aftermarket. If these are to your liking, we can install those as well at AutoMetrics.
