I know you can change the glass packs in the Hooker Headers/Sidepipes of the competition headers. My question is this... I do know that since putting these on, I have a restriction. naturally you would, look at the collectors, to the glass pack size differeence. Like 4 incehs down to 2inches tops. Does anyone know, can I get a different glass pack taht will fit these with a larger opening? I had better performance with my 3" exhaust on there, but had to take them off with the installation of my 700R4 transmission in my 76 vette. Any help would be appreciated. Thanks
