I have a 2004 F-150 FX4. Going to be doing both side manifold change. Looking for opinions on best brand replacements (no header) just stick set up. Also if anymore has done should I also replace all studs with knew and if so what type(stainless etc..). I got the system down for removal and replacement just looking for advise on parts. I hate having to go get parts after I have started a job. Any help would be great. Or even if someone has a complete parts list even better. Thanks
