Is there a benefit {either performance or weight} for a stainless steel header over a cast one with ceramic heat paint applied? My guess is that the stainless is much smoother inside and may perhaps flow better, along with probably being lighter. I currently have an obx with the ceramic heat paint and wanted to know if there was an advantage in going to the stainless steel type. A hi-tech is out of my price range and the d.c. sports seems to be hard to come by, so can anyone recomend a particular brand/type? thanks Jeff W. st22
