Ok, here's an exhaust 101 Q--

Other than emissions, what purpose does the cat serve? Do cats affect gas milage?

All I know is they " convert " CO2 to less harmful amounts, & get hot.

We have no ECM, so there's no O2 sensor. Til I can afford a good cat, we have a " temporary " pipe in it's place.

Thanks for any education!!

 

Its emmisions equipment. Thats it. I have none on my Camaro.

 

Thanks for the info!!

 

With an ECM, adjustments can be made from moment to moment which MIGHT help with mpg.

Without that ECM tuning going on, I don't think it would have much, if any, effect on mpg. Unless it was a clogged up/bad flowing one. Then that would be more of having to depress the gas pedal further to create more power, just to get a car to move. But that would be the case even with ECM tuning going on so.....

 

an engine needs to inhale & exhale just as you & i do . if cat. is old it may well be clogged . try to inhale through your nose & exhale through your mouth covered with a paper towel . you can do it but your not going be doing anything to your full potential . there are many " hi-flow " cats. out there , and many of us ( me ) have eliminated our cats. yes a clogged cat. can affect mileage . whatever you decide , good luck .

 

Actually catalytic converters convert carbon monoxide (CO) into carbon dioxide (CO2) among other things.

Cats tend to get rid of the rattling sound that exhausts have when you rev them up. Also help act as a muffler to a certain extent.

 

It doesn't convert c02, when it reaches 900*F it converts HC's and CO to CO2 and H2O, and reduction converters also convert NOx..

Perform a vacuum test to determine if its plugged.

 

Thanks for the education!

So since we have no ECM, the temp pipe will have to do for now.
