Dont get the BBK pipe. I have installed 2, and we had to use a 3 ton floor jack to spread the pipes to mate to the BBK headers. Also, they are having quality control problems because My headers had leaks at the primary welds, plus one of the pipes on the hpipe was not balooned out enough, and the clamp used to mount the muffler to kept popping off. Next time I will go Mac, you can buy direct from them, no middle man to deal with if a factory defect comes up. Do your self a favor, stay away from BBK.
