Muffler Design & Performance

Donaldson mufflers are designed and tested with a specific focus three performance variables.  Be sure to select a system or replacement parts that are right for your application.

· Attenuation

· Refers to the reduction in sound level measured between an engine without a muffler – and the same engine with a muffler

· Measured in the decibel scale (dBAs)

· Traditional mufflers use tubes, baffles, expansion chambers and insulation to control noise

· New applications include emissions control devices

· Engine manufacturers generally expect engine exhaust sound reductions of 15 - 25 dBA

· The EPA also regulates noise levels

· Backpressure

· Refers to the force necessary to flow gases through the exhaust system, or the resistance to flow

· Excessive backpressure can reduce horsepower and fuel economy

· To promote efficient engine performance, minimization of backpressure is very important

· It's important to minimize system friction and momentum effects – expansion, contraction, elbows and velocity head loss at outlet

· Our muffler specifications offer suggestions for proper selection to reduce backpressure

· Structural

· Structural durability of systems and components is also very important

· Variables to consider include position, mounting support, weight and material type

· For example, if an OE specifies a particular system, and you install a heavier system (such as an emissions control device), its critical that you upgrade hangers, brackets and stanchions with more robust components that can support the added weight

· Most exhaust system problems seen by our field service techs are due to improper bracketing or use of clamps – rather than issues with muffler construction
