Active Autowerke E9X M3 cat stubbies

[Yomny@ActiveAutowerke]

This is specially for those weekend racers. The AA stubbies allow you easily swap between your stock cats and our catless xpipe for weekend races then daily driver duty.
Just a small incision on your cat, weld our stubbie and you have a swappable piece.

PM for me for more info.
