I would buy test pipe stillen for my Z. I have stock exhaust and i would to hear the sound of that.

Anyone have video of that ?

Thank you.

yo man, i cant speak for testpipes, but i have RT cats, and i love the sound with the stock exhaust. its a bit louder, a bit raspier, and quite a bit deaper. i dont think there are any videos of that, but i can tell you that i like the way the RT cats sound with my exhaust. hope this helps.
