So I started to pull my tranny to replace my rms and i pulled of my old beaten bbk h pipe, I have a new cat back and x pipe that is going back on the car when my rms is replaced. I pulled the new x pipe out of the box to compare to the old h pipe. Almost the same but a little different. i go to check to see if it will bolt up to my bbk headers and not going to happen. i just called summit racing to see if my order is correct and it is for my year and model. The headers are about 6 years old. Did bbk change the flange location on the same headers. I cant figure this out. The old h pipe is also a bbk unit. I even went to bbk site to see, and it says I have the correct stuff. BUT I DONT.
