Sounds great, massive improvement over stock.

I cannot say I love the sound of the new car from the factory, but you guys definitely made it better. I'm looking at purchasing your race exhaust for my e39 m5 next summer and cannot wait.

This is the best sounding I've heard from this car. Akrapovic should deal with it.

IMPORTANT: Watch in HD.

Is this axle back or full system?

[@Consigliere..]
