Preview of ESS Tuning S85 V10 (M5/M6) long tube headers designed specifically for forced induction
ESS will be entering the competitive, expensive, and lucrative E60 and E63 M5/M6 header market. These headers were designed with the ESS supercharger
in mind and will be used on the V2+ and V3 supercharger kits whenever those actually come out. RPI will be carrying these headers which is interesting as they also have a header application for the S85. The difference of course being these are new larger diameter designs with forced induction in mind while all the other headers options available currently are intended for naturally aspirated applications. No word on pricing, but likely not cheap as all S85 headers available are expensive.
