As long as it has cats, you should pass inspection without any issues. As was mentioned above, the CEL issue can be easily addressed with the ECU tune.

Feel free to let me know if you have any questions, or would like a quote on the system.

Tom,
Do you stock the 2nd gen system? I saw it on the main Japanese site last year but couldn't find anyone selling them. These are said to solve the HP loss issue with bigger pipes.

The valves on the F1 are known to stick open or closed after a while. Keep them in good working order.

We get the systems directly from the US distributor GT Haus. As far as I know it's the most current system.
