We have designed, developed specific Step Headers options, for the LHD and for the RHD M3 versions.
They have 63.5mm, full-lenght oversized downpipes, which slip-fit into the Supersprint, dual-pipe full system.
Over the years, the Supersprint Step Headers and Exhausts have been known to guarantee the greatest gains in mid rpm torque, and in peak hp as well, widening the usable range of the S54 powerband, effectively.
Our exhausts have become proven winners among the entire E46 M3 community, worldwide.
