I need a link for header installation if anyone have them. Planning on installing header either professionals or someone's help, just want to know how hard it is before i make a deal. Thanks.

 

I just installed a set of stillen headers on an 03 G35 today. Its not a backyard procedure. I can copy the directions and send them to you and walk you throught the steps not in the instructions. Btw i also installed a supercharger on it and full exhaust f*ckn crazy. Its and auto but a blast to cruise around in.
