IP: Logged
Message:
Is anyone running a high flow cat on a 02 4.7?
If so, did you encounter any problems with the 02 sensors? Thanks

i'v just heard from some friends that the hi flow can tripped their o2 sensors. So I just wanted to check before I get my cat this weekend.

if you have 3 cats, there is no O2 sensor on
the third cat, chop it off and quit worrying about
it.

there is a o2 sensor downstream from the last cat. when gutting it, or taking out the 3rd cat, SOMETIMES it (the downstream o2) trips a code, and you get a CE light. this is where the kat box comes into play.
if you are just doing a high flow you shold be fine.

I don't know what size it is, I was just going to go down to the shop and get an estimate and maybe get one put on. I thought the 02 had 3 cats, but when I look under my truck, I only see one tube besides the ones going to the muffler. So i'm confused?

Chris, Look way upstream from the Y pipe.
They are called precats and they are just
below where your headers would be.

alright bro, thanks. That totally cleared up my sudden concern. So I can get the hi-flo cat that sits right below the passanger side door. But the next question that I have is. If I get headers, this will replace everything down to the Y-pipe. so I will end up losing the 02 sensors? and then trip a code for sure. Or am i once again not getting the point?

I just looked and there is an 02 sensor after the 3rd cat, and 1 before it.So if I go with a hi-flo cat, I wont trip anything?

the only headers that are availabe are the shotys, which bolt up to the stock Y-pipe.
a high flow cat, should not throw a code. i have one on my 318, and its fine

Chris - They must have changed something on the 02's then, becuase on my 01 the other day I spent quite some time checking out the exhaust system, and didn't find any sensors other than the four that are on the precats.

I guess if it throws a code I can always be gay and have the old one put back on and have a hi flo cat up for sale. Lol..

Some of the 4.7 trucks have only one cat.
My 2002 has only one with the 02 sensors before and after. I don't know why the trucks are different.
