The 1979-1983 Alpina E21 B6 2.8, based on BMWs own 323i, is one of the first conversions to the larger, M30 6 cyl. engine ever made.
Other tuners had soon come out with other versions, tweaked to larger displacement and more hp, such as as the Hartge H3, which used the 3.5L engine, taken straight out of the 635csi.
Supersprint was there from the very beginning, developing, building our legendary long-tube headers, and completing them with oversized diameter, high flowing exhausts, to match the engine specifications, and ensure the maximum performance gains.
Now 35 year later, we still offer the same exhaust systems to the E21 enthusiasts, worldwide.
All of the Supersprint exhausts are designed to perform and built to last, as always.
