Akrapovic has been gaining quite a reputation in BMW circles by becoming BMW’s exhaust partner for the BMW 1M coupe safety car and the BMW F10 M5 safety car. And now Alpina, the legendary BMW tuning outfit, has also turned to Akrapovic for its latest creation - the Alpina B6. It looks like a relationship which should continue for future Alpina models.
The Alpina B6 Akrapovic titanium exhaust system is 23kg lighter than the factory steel exhaust. This represents a 45% weight reduction.
Official preliminary specs on the Akrapovic exhaust systems for the BMW 1M Coupe have finally been released by Akrapovic, at the 2011 Frankfurt IAA. There are two exhaust systems available - an axle back and a cat back system. The preliminary figures indicate a +15hp / +19Nm tq gain, with a 16kg weight reduction over the factory 1M exhaust system. Videos, pics, specs are inside.
