I just ordered & installed the CNT hfc from nissangen's groupbuy. There are built in 02 extenders and I have not received a code(only had it on for like 2 days). It definitely makes the exhaust sound a lot deeper and louder, and hiss is VERY minimal. There is sometimes an exhaust burble sound, some people like it, some people dislike it.
