i only buy quality unless there is none suitiable for the vehicle im working with. i use pacemaker headers where i can. pipe over cone high build quality quarenteed fit and lots of r&d and also they are just accross the pond from NZ in australia.we did just use some hedman headers on an elcamino as they were cheap and all we could get here and they were known to fit LHD but they were awefully short looking and a couple of bends were questionable but all in all ok
