most header will have a d/p to connect to the cat, u'll have to check....not too hard to install, just put the frontend on jack stands and don't rush and use the copper high heat rtv to healp seal. i have a family too, 17 yr ols senior and my son 14 in 9th grade and he wrestles for the school. me and wife are in last semester in school starting back next week. my credit is phucked and i'm almost always broke so i know modding is ruff when u have ideas and no $$$. what u can do till u get the $$ for the right headers is to keep stock pulley on, do the other mods and take off the front manifild and port/gasket match itto the gasket. its temporary but it might help a little.
