Question reg ets downpipe
My z had test pipes and hissed like a mothafugga. Seriously I would hit the gas and hear ssssSSSSSSSSSSSSSSS
Totally normal, that's what test pipes do (an a z, and i'm assuming other cars too...) My car seriosuly sounded turboed the hiss was that loud. I'll post a vid later if u want to compare to ur sound.
