Does the emissions control system meet sound attenuation requirements for the location and purpose?
If you are purchasing a combination product such as a filter/muffler or filter/silencer or scr/filter/silencer, make sure the product offers the level of sound attenuation required for the application. **CleanAIR products offer double-walled construction with full-body insulation and three levels of sound attenuation. Full-body insulation not only reduces exhaust noise, it also helps to contain exhaust heat.
