Ok guys I know the hi-flow cat question has been beat into the ground here. I have searched but now I need some help. I have a guy that will do the cats, and no emissions to worry about so I don't need to know about that. I am just needing to know if there is a magnaflow hi-flow cat that has the 02 censor in the middle. I was looking at the cats (only 2) on my truck and the 02 censor is placed in the middle of the cat. I would like to know which hi-flow will with stand the heat and not throw CEL. Thanks for all your help, I know the issue is beat into the ground but I could not find the right part # anywhere.

 

I've never seen that. I would assume as long as you buy a normal high flow and put your sensor in a bung before the cat...you should be fine.

 

or get an O2 simulator

 

The cats on your truck operate as filtering gases, and sound resonating. The reason the sensor is in the middle of the cat is because thats where it monitors if the gases get burned ( pre-cats job on 4 cat systems ) and the other end resonates sound down, no need for those to be monitored.

So in general, you can get any Magnaflow cat and mount the rear O2 sensors after the new cat and you will be alright with no CEL.

 

All right thanks that is what I needed to know.
