Greetings long time no update

After i went fully stock on my ZHP, i found a guy was selling his E46 330 Gruppe M air filter. I couldn't miss the chance and i bought it. I was looking for one since i bought the car. The sound is amazing like a V8 and when accelerating it's got a nice whistle sound.
In the nearest future i am planning on installing the headers, but at the moment i am looking for a ebay header that doesn't need welding and it's bolt on. As you saw in my previous posts the previous headers was a headache since i modified three O2 sensor ports and still wouldn't work.
