Does anyone know the part number for the Pacesetter header for an Ecotec Grand Am, I found multiple listings on Pacesetter's site and got a bit confused as to which one unless I'm missing something.

Also, did the header make your car a lot louder, more cabin noise, lose any bottom end? Thx for your help.
