issue i had lol. this post was about 3 years ago, when my NA was stock. well, i may've had my exhaust by then, but i'm pretty sure the post wasn't on this board. at the time i didn't know much about a Z at all, and i had a hard time believing my NA would top out so much less than my friend's probe SE. i didn't frequent this board much at all back then, i was a Z32.org whore. sorry for posting misinformation. i don't care for top speed much anymore, so no telling how it'd run that high now...
