yea...I notice 2 different styles as well. I have no idea whats up. Maybe 2 different production runs? I have never heard of this, but I guess its possible. Tony at AWR and I installed this at his shop, so I know its the real deal. hehe
The reason I sold mine was because I had to have my car smogged this year. Also I had a MAM catless midpipe installed and the smell was godawful. A friend was walking down the street and said it reeked big time as i went by him. lol So, a cop can surely smell this too. I dont want any trouble from the law when it come to emissions. So off it goes!
Oh, mine was not loud at all with this header. I did have the full stock catback in place too, as to keep it rather stealthy looking from the back and the sound low.
