CAE headers. Castle Automotive Engineering. Very well made. I tried to use the pacemaker ones, they look great but they dont fit, the collecters hit the floor pan and and the pipes touch the firewall. Thats what you get when you use a cad. program to design a set of pipes and dont use a car and motor to make them on. I did speak directly to pacemaker and they sounded supprised that my pipes didnt work with the CRS mounts. They wanted to look at it but lost intrest once they realised it was going to be a drive to the country side to inspect the job.... oh well. Wonder if they have fixed the problem since ? pm me if you know.
