>>HP Autowerks<< Akrapovic 135i (N54) Downpipes
The BMW N54 twin-turbo engine is a true factory-made beast, but Akrapovic's engineers developed a special aftermarket downpipe system for it, which makes the N54 even better. These down pipes are designed for drivers who demand more power and less weight. In addition to a weight reduction and a power gain, one of the tasks of the Akrapovic team was also to make the sound of the N54 become music to ones ears.

I second that question. PM me shipping cost to Australia (3142).
I've got the BMW Perf Exhaust, any test with this set up to know gains in perf and sound. |

I guess the sound will improve, but it might be a problem with authorities. Also, I assume those will generate an engine light at the dashboard. Is there something we can do? Final question, what about emission, still legal? The 135 N54 has rear cats, will it be sufficient to pass emission tests? Thank you!

Does anyone know the gains of these downpipes in comparison to say the CP-e, AR & BMS downpipes?
