Alright, I have stock headers on my car and a bbk h-pipe with flowmaster catbacks. I want to get some new headers but how will I know if they'll fit my midpipes without knowing my h-pipe's specs? I'll basically have to get headers that are the same size as the stock ones right?
Any help is appreciated, thanks.

) BUT since you have the bbk hpipe I would say get the bbk ceramic shorties. the ceramic coating dropped header heat by 200*
