is that your theory or is it proven? cuz as far as i kno there is no right or wrong answer untill proven if u find anything hit me up with a link

 

hi, guys i'm back i decided to go for the term "what you pay is what you get" so I decided to go for the DC sport headers, I also bought a resonator from e-bay, what is the difference between a resonator and a catalytic converter.

 

I thought this thread was about headers.........

 

A catalytic converter treats the exhaust before it leaves the car and removes a lot of the pollution.

The reduction catalyst is the first stage of the catalytic converter. It uses platinum and rhodium to help reduce the NOx emissions. When an NO or NO2 molecule contacts the catalyst, the catalyst rips the nitrogen atom out of the molecule and holds on to it, freeing the oxygen in the form of O2. The nitrogen atoms bond with other nitrogen atoms that are also stuck to the catalyst, forming N2.

The oxidation catalyst is the second stage of the catalytic converter. It reduces the unburned hydrocarbons and carbon monoxide by burning (oxidizing) them over a platinum and palladium catalyst. This catalyst aids the reaction of the CO and hydrocarbons with the remaining oxygen in the exhaust gas. For example:

The third stage is a control system that monitors the exhaust stream, and uses this information to control the fuel injection system. There is an oxygen sensor mounted upstream of the catalytic converter, meaning it is closer to the engine than the converter is. This sensor tells the engine computer how much oxygen is in the exhaust. The engine computer can increase or decrease the amount of oxygen in the exhaust by adjusting the air-to-fuel ratio. This control scheme allows the engine computer to make sure that the engine is running at close to the stoichiometric point, and also to make sure that there is enough oxygen in the exhaust to allow the oxidization catalyst to burn the unburned hydrocarbons and CO.


The Resonator

Some cars, especially luxury cars where quiet operation is a key feature, have another component in the exhaust that looks like a muffler, but is called a resonator. This device works just like the resonator chamber in the muffler -- the dimensions are calculated so that the waves reflected by the resonator help cancel out certain frequencies of sound in the exhaust.


Hope this helps you understand the difference.

 

nightrider46....sorry to butt in on this whole forum-war you guys got going...but just think about all the components of a "good" exhaust system. Free-flowing headers, 2.5" piping, then a big ol' muffler. Every single component is more free flowing than the stock one, so how can you say a smaller, more restrictive pipe will give you better torque? If this is true, why dont you get more restrictive headers and 1" piping all the way back? Sorry man...just gettin my opinion out there...

 

Holy thread from the dead.
