just ordered Ark Grip.....
 

I've been lurking in the shadows on this site since I got my car (12 black vert) 6 months ago. Last month I installed braided lines & powder coated my calipers red. After reading every thread I could find & listening to sound clips I just pulled the trigger on the Ark cat back. I'm an old guy so I don't want to be obnoxious but needed a better tone than the stocker. Hope I made the rite call......

Ark is pretty good. Most people here use Fast Intentions. The ark has a nice tone and sound. Good luck and post pics !!!!

You will not be disappointed. It is a very nice sounding and good looking exhaust.

It's a great exhaust. One of the best tone I've heard on the Z, you will not regret it.

im running arks grip v2 with non res test pipes, i ******* love them get compliments from car guys all the time

l love mine, Sounds GREAT with my HFC's!!

On YouTube it sounds very nice and deep.... I love the sound, I've never heard it in person just on YouTube but it seems kind of quiet, maybe it was recorded on a phone or camcorder ? It just seems a little quiet for me correct me if I'm wrong.

It's quiet at cruising speed but it's not stock like quiet, you'll know it's there. At wot it sounds great! Especially if once you combine it with an Art pipe.

And there are many people here who use other products, like AAM.
