Anyone have hfc's in western WA.?
 

Considering picking up some high flow cat's to give the exhaust a little more growl but am wondering if they will pass emissions? Don't really want to have to change back to the stock ones to pass. Sorry if it's been asked before did a couple searches didn't really find any answers.

They should pass. I have Berks HFC and passed emissions last summer no problem

Berks will most definitely pass. They are 49-State compliant.

same here, my Berks passed in October :D

i have headers test pipes and the XYZ pipe with the HFC and it passed in pierce county

As long as you're not throwing a CEL code, you should easily pass. Most cars running OBDII don't get the sniffer on the dyno test, just a quick OBDII scan. I had to have my 04 Titan checked for tabs the other day and that's all they did.

Thanks guys for your help! Looks like Berks are in my future.

What year Z do you have? I'll sell you mine and give you a good deal. I just took them off a few weeks ago. They are for 07-08 HR though.

I have an 03 Z with 41,000 on it.

I have the Motordyne ones, passed emission twice without issues.
