I was wondering if anyone can enlighten me on headers for my 2004 mustang gt coupe. I have been looking and looking and i really dont know what to go with. I have been looking at the bbk, pacesetter, jba headers but i do know that longtubes have better performance thatn shorty headers. any ideas on what brands to go with and would it matter besides the obvious longtubes being better? any ideas would help.
