To the OP, thanks for the pics! When it comes to a sports car exhaust system, I feel itās about sound, airflow/power & torque increases, and looks - in that order. We already know the sound of the manual Z (my choice) is lacking due to the more restrictive exhaust it has (for sound regulations) than the automatic. So, Iāve gotta see videos posted with sound before Iād even entertain shopping exhaust systems. It wonāt be long before the aftermarket floods YouTube (and their own sites) with a plethora of Z exhausts. All that said, the vertical stack isnāt my favorite but the oval tips look nice.
