The original. The Bavarian Muscle Tee is where it started — first released in 2013, last available in 2017, and now it's back. The graphic is a hot-rodded M-Tech 1 E30 — a nod to the Southern California hot rod roots where BimmerHeads got its start. The design hasn't changed. Neither has the standard.
