KCustom, she sounds surprisingly mellow and dare I say exotic. I have never heard the Delta 40s ever sound so tame. They have always had a deep sound that sang at the note of the lope of the engine. Putting Flowmasters on a new 70k+ Bimmer is truly epic. Hats off good sir, on a job well done.

Btw, that M5 diffuser looks great painted.
