I need to change out my cats on my 2006 f150 I was think taking the stock cats off and replacing them with these magma flow cats, I'm just curious if I will run into and back pressure or technical problems after swapping them, any advice would be great , thanks in advance

 

Nope..

 

should work fine as long as the O2 sensor is supposed to go in the cat.

 

Sure you dont need this one? http://www.summitracing.com/parts/mp...50?prefilter=1

 

^^^this is the correct one ^^^

 

Thank for the help, very much appreciated

 

I have pretty much the same cats on my truck and I didn't run into any issues.

 

Might wanna double check if the one from Summit listed above is right. I know the cats on my '06 5.4 have the O2 sensors in them.

 

This is what I am not sure about. Maybe in 05 they changed the location of the O2 bung.

 

On my 06 there's a sensor before and after the cats but not on on them
