ALPINA B6 (E21) 2.8i ' 79 -> ' 83

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.

Systems for replacement of kat for OBD II car models (with lambda sensors before and after the kat.)

These systems can only be used for racing purpose exclusively, in conjunction with the modifications of the engine management system. If used with a stock “ECU”, malfunctions may occur. All modifications must be carried out by qualified personnel only, under the liability of the car owner and at his expense.

Supersprint guarantee is limited to the quality, workmanship and correctly fitting to the intended car model for all race products.
