My dad is really worried about my dumping my flows becuase of carbon monoxide poisoning... I told him if people ever died from it that you would hear it on these boards or on the news. Hes just looking out for me but i dont think it is a big deal at all. I am going to be running bbk equals, mac 2 1/2 o/r h, and flowmaster 2 chamber dumps. Give me your opinion dont flame as i will have him read this!
