Still love the Stillen TD exhaust on my Z33 track model. Sound really rips at higher RPM, but is quiet and composed when cruising. Wonder what they'll release first for the new Z?
Heard an exhaust comparison video on the Q50 Redsport, and the Stillen had the best note IMHO.
I know there will be a little difference (pipe length et al) but hoping it's pretty much the same.
