catalyst convertor chices: high flow

[barry G]

I am in a 49 state legal realm..

what cat can go to 7000+ pounds at 100 cell per inch or 200 CPI?

v8.

 

I can't seem to find one.

I find the very common 5000-6500. That is an empty truck. Don't want to use it.

 

any recommends?

I also want post obd2, or 3 way (the newer sulfur cats)

What do you mean post OBD2? OBD is just a diagnostics feature. Do you mean post O2 sensors? If so, no need to worry about cats at all really unless you are worried about reducing pollution. Post O2 sensor cats wont trigger a CEL, thus wont affect your inspection, if that's what your concern is.

Unless your cats are clogged, your OEMs are already high flow.

thank you. I did figure that out.

I went with bad fuel as a routine, changes were better going good fuel.

 

post obd2 simply means 3 way cat.. it has a sulfur extra like diesels.

I could safely guess 55psi fuel and multiport goes with it.

 

they also respond to cleaners and higher octane.. that is where I went with it.

bad gas station had me wanting to hack it right out for a time.

 

An EGT right at the cat would be interesting, it roasts when you get bad fuel...then the stinker, then almost noticable power loss.

 

Doing good now.

 

..and by high flow, I mean REALLY high flow, like 200 cell. Very open.

they ignore weight limits, only choosing to limit by liters from what I have found.
