Thread: Catalytic converter?

I'm told my kr problem might be related to the cat conv being clogged up.
Being that my car is runing rich,it might of clogged it up.
Reason for my afr ratio to be 10.5@wot.
Is it safe to run with out one?
Will it affect perfr any?

i dont have one and i havent seen any ill effects. you wont pass emisions tho

you can pass emissions so long as they dont do a visual check. you just have to use an o2 sim or set the SES code to no report for the rear o2.

humm. well there you go

Well if your cat was clogged up you'd be seeing abnormally high boost numbers. How much psi are you seeing at wot?

^^ good point, didnt think of that.

youre making 11psi on a 3.2 which is about right. have you tried leaning it out, or no matter what you do it is always rich?

Ya boost looks fine. Definitely lean it out some, if you still get a good amount of KR then pulley up.
