I got my new HP racing header and high flow cat along with a sim box. I have a few questions. One of the ands of my high flow car is slightly angled. Are both ends supposed to be square and I am a little confused about teh sim box. Does anyone know what the blue wire does. I will post pics. Plus, there is a small dent on the end of the high flow cat. Tell me what you guys think....
