Yes, afterburners are the best "cheap" set to go with. Uncoated they are about $200 and coated $350.
Keep in mind even with coating headers do not last like manifolds in a humid area. I had a long conversation with Bruce from Stan's Headers about header life. Humidity seems to be key. I am sure salt (NY, NJ, North East) has something to do with it. Running a car is better than sitting or on/off. According to Bruce, dry head is the best atmosphere. The factory just re coated a set off of the Stan's truck that were 15 years old. In southern Cali mind you. They were not stainless.
Seems that to stay totally rust free you have to had 304 stainless. Big Bucks!!!
Jason Chapelle has a set of these for sale...........
