I'm going to ask a dumb question . What is a resonator and what does it do ? Whats the difference between it and a muffler ?

 

I knew this was a dumb question but I thought someone would take pitty and help answere the question.

 

it is a catalytic converter. lowers emisions and quiets exhaust. I think the older trucks had the resonators. pretty much the same thing though.

 

Newer Megacabs have this small muffler type device on the tailpipe over the axle that is called a resonator because by design it reduces the resonance in the cab. Newer Quad Cabs do not come with one but the older trucks may have...It is not a CAT...

 

Resonators are usually bullet shaped small mufflers that are louvered internally, not chambered. This usually includes glasspacks and race type mufflers, that are designed to bring db levels down. Catalytic converters are more intended for emmisions catalysts, but its extended benefits are sound resonance.

 

My 04 quad cab has a resonator in the tailpipe right as it goes up ove the axle.
