Hi flow cats pass emissions tests
 

I would like to install hi flow cats on my 370 7AT. Does anyone in the DFW area have experience with these and know if they will pass the large city emissions test for Texas inspection sticker?

I have test pipes and I pass...lol

As long as you aren't throwing a code you should be fine.

My Z is a daily driver and having it sidelined for anything would be a great inconvenience. I want to be sure before pulling the trigger on mods. Thanks for your input.

What are you planning to go with?

I am still researching. I am told that on the 7AT not all hi flow cats will fit with all the O2 sensors installed and functioning. I have verified that Berk and Invidia fit and operate correctly on a 7AT. I called Z1 and was told their Kinetix fit the 7AT, but the sales person didn't sound confident. Maybe another forum member has had experience with Kinetix and could tell us.

Stillen HFCs fit properly with a 7AT.

Even if they throw a code, a tune will clear that right up.
