I had an AA NA Stage II E46 M3, so I'm not one to cut corners. I know all about expensive modding. I just find even the $595 intro price unreasonable.
Considering the total money spent = 2 pipe plugs and some tape, I don't think it looks bad. The sound is actually quite nice. I have to get a good camera that will capture the sound well.
I may consider buying a two new hoses, and cutting them up to fit a universal BOV and see if there's much of a difference.
But I am actually very happy with the current results.
AA M3 is gone...the new...
