Has anyone installed the new Stillen High Flow Cats? I'm worried that the High Flow Cats will not pass emission testing, but not sure. Advice??

I installed the Stillen exhaust & intakes last month. Waiting for TechnoSquare to come out with the G37 ECU program.

 

i do not think it will pass emission, thats why its recommended for off-road used only..that do not stop people from putting it on and driving it daily.

 

Check out the BERK HFC's → BERK ← Excellent build quality, and they have brackets to attach to the factory brace. Also 49 state emissions legal. They have gotten great reviews over at my350z

 

Thanks for the information Gents! I sent an email to BERK, and think I will purchase their HFCs. They said the BERK HFCs will mate with the Stillen exhaust and they are 49 state Carb approved.
