ALPINA B6 S (E30) 3.5i ' 91 -> ' 92

Supersprint has the perfect exhaust for the unique, extremely rare 1991-1992 Alpina E30 B6 3.5 S, and for the Hartge E30 with the M30 6 cyl. engine conversion.

This Supersprint system had become very popular among the Germany tuning scene in the 1980s.

The 3.5L, naturally aspirated I-6 engine, modified and tuned by Alpina, and by Hartge as well, craved for oversized, long runner tubular headers and a for a free-flowing, large diameter dual line exhaust.

Supersprint developed stainless headers with the ideal diameter, runner lenght on the primaries and the downpipes sections, which guaranteed the best performance gains.

Also, our mid resonator and rear muffler, with their straight-thru design, inner perforated cores, provided for a lower exhaust gas backpressure and for an awesome sound.

Fast forward to 2020, we still offer this same exhaust for all of the E30 custom projects with the conversion to the M30 engine.

We can proudly say that the Supersprint 304-grade stainless steel performance exhaust is the most effective, durable addition to these fine BMW, Alpina and Hartge cars, making for a long-term investment.
