The new headers have 63.5mm, full-lenght oversized downpipes, which slip-fit into the SS, dual pipe full system.
Over the years, the Supersprint Step Headers and Exhausts have proven to offer the most gains in mid rpm torque, and in peak hp as well, widening the usable range of the S54 powerband, effectively.
Our E46 M3 exhausts have built their reputation and earned their success at the International Racetracks.
