Does anyone know if having a Berk technology 63.5 high flow cat will throw a CEL code?

 

i got one installed a month ago, and yes it throws cel. you can buy an injector fouler, drill through it then put it onto the HFC then screw the o2 on to it. after that cel goes away

 

Why would a HFC with stock oxygen sensors in stock locations create a CEL?

I just ordered one one to help with the drone from the Greedy Elite Dual exhaust and DO NOT want issues for a simple bolt on!

Is this AP1 or 2 ?

 

My 70 mm Berk HFC did not throw a CEL on a MY00.

 

Total BS!

It should not throw a cel. I had one on my MY04 AP2 and had NO issues with it.
No need for a defouler.

If your car has other issues with it, then it might throw a cel.

 

No on my 2000 berk 63 hfc. Do the Ap2s have different 02 placement?

 

The 06+ AP2's are known for having this issue. If OP has an AP1 or 04-05 AP2, then he should not have an issue. OP - what MY do you have?

 

Y'all need to research more before calling bullshit.....

 

i have an 01 and it throws CEL every once in a while randomly for the berk HFC

 

I have a 06 with 70 mm, no CEL.
