Supersprint V1 Stepped Headers
For many years, the Supersprint V1 Stepped Header has come to fame as the absolute top performing header for the E46 M3 and S54B32. Proven through the test of time, it is a crucial ingredient to making maximal power out of naturally aspirated or supercharged E46 M3 and S54B32!
It utilizes a very large 63.5mm outlet flange. For true OE integration, we suggest purchasing the Supersprint V1 SPipe with cats (PN 044002) or without cats (PN 044012).
