Looks like Valvetronics completed their axle back and are now offering a combination of the midpipe + axle back at a very appealing price point:

Looks like the car they installed the axle back on is
G80_Soom's car - if that G80 M3 has catless downpipes + the full Valvetronics exhaust then I cannot
wait to hear it! It sounds crazy aggressive with just the downpipe + midpipe, can't imagine a full setup.
