There are CHEAP headers out there! But you get what you pay for --- steel that will rust out in a short time vs stainless that will last! Ceramic coated ---- bare metal! Tuned & tested on a dyno ---or just bent to shape & maybe a fit & will they flow as they should! You be the judge!
Truck action is right cheap headers have crude welds cheap flanges that will leak and sound horrible I've herd of people getting pace setters and having them work well and others failing in my opinion if u purchase something that is going to be exposed to massive heat and expand and contract constantly u want it to be of quality like lc engineering or Doug thorly .not bashing pace setter just going of what I have seen and owned I also like the fact that lc and thorlys are researched and developed .not just big tubes
My vote is for Doug Thorley just like [Yotaforce & scrub88] stated. It comes complete with the O2 sensor hook up as well as the air injection. There is a Carb E.O. #, so this will pass the visual of our famous CA Smog II/test only. Rick
