how many people here still have cat's ?
|
If someone has one and doesent need it (emissions wise) I think it is removed asap....I know i did...I have never lived in a state that required emissions thank god!!
Good info as i did not even think of that (as far as the ic getting cloged up)
and may be bennefictial of me knowing since i may be ic'ed soon![]()
when you idle the cat gets hotter (you tend to run a bit richer, and they were designed to have airflow) that is what they always told us in the tech classes, and even when I went to independent shops the muffler reps all said the same (walker claimed over 75% of failures were due to letting the car sit and idle)
Weird....See, I was reading about this yesterday (and I'm not wanting to argue here)
The converter hardly does anything while idling, in fact the emissions are through the roof when idling. The best way to warm up a catalytic converter is to drive the vehicle.
I don't know....like I said, I was just curious.
Correct me if im wrong but dont you still have 5 other cylinders running through the cat. the egr valve is only on the cylinder number 6 right? it just dosnt seem like the pressure from the other exhaust ports will travel up against the pressure of number six since it looks for the esiest way out.. but i am running no cat so less backpressure with that and headers
lol, backpressure.
It's all about exhaust scavaging.
People need to research.
uhm thats why i said correct me if im wrong im learning here were all human. but i guess some others just know all and im not one of them ... My bad.
