i have ridden in a car with the mod, most will not agree with me but the mod makes the exhaust more raspy and tinny, louder yes! but i prefer the more deep throaty sound and therefore i would not do this mod.
this mod effectivly gives you a straight pipe sound because the exhause simply goes right through the muffler without the benifit of a chamber to allow the exhaust to resinate in.
most will like it but the funny thing is i run my totally stock exhaust with the bypass open and on more occasions than i can count when i have left the stoplight under heavy throttle the next light will bring all sorts of questions about what exhaust i am running that it sounds really good and people are in total disbelief that it's stock.
for me, the rule applies, if it aint broke, don't fix it!
i control my exhaust bypass through my kenwood stereo with an external output i labled "exhaust bypass" i have another open switch and output for lights or anything else i want to control.

Verified during a disscusion with a GM Rep. at their setup in Carlisle. The mod caught their attention and deciced it was an easy design change for them.Makes the Z sound like the animal it is while appeasing the sound police.

however i still like the throaty tone of the stock exhaust pre 2011 but if i had a new 2011 i wouldnt waste my money trying to change it.
i guess the bottom line is it doesnt bother me either way.

Richierich, who had modded Z06 mufflers on his car and then switched to a set off a ZR1, said the ZR1 units sounded significantly better.

I saw the video of the unveiling of the 2011 Z06. They specifically mentioned that the 2011 bi-mode mufflers had no perforations similar to the NNP and ZR1 exhausts. I don't know what, if any, other changes were made to the system, or even if they are exactly the same mufflers as on the ZR1 (though they have different part numbers).

I have American racing headers X pipe and muffler mod. The muffler mod with the headers sound very different than without. I love the sound of the mod with headers and think it was one of the best things I could have done to the car. At WOT the car sounds amazing and at idle the car sounds like this is not a car you should not be messing with. I wouldn't hesitate to do this mod again.

I didn't realize that you could program the mild to wild to the visor. I have the mod with headers. I love it - very aggressive sound and not too loud for me. Much louder than stock. I love a loud burbling exhaust note.

Just have your remote program/learn to the visor like your garage door opener. Instructions in the manual, I think 2008 does not program but 2007 does, check it out.

I've heard this mod in person and it sounds AMAZING, I would never bother with an aftermarket catback if I had a C6Z. 
Definitely see Steve for this mod if you are in the area, he has done a bunch of work for me in the past and I can highly recommend him!

Had mine done when I installed cam and headers. On "quiet" almost sounds like stock, on open everyone stops, and looks. For the cost it can't be beat. You can spend much more money for a marginally better sound, and you won't have the option to switch back to quiet.

Recently did mine, have longtubes and no cats. TOO LOUD at WOT. Put cats back on and it's perfect. Louder than stock, little bit of backfire upon decel, and idle is deeper and not too loud. I'm a happy camper. I couldn't imagine this mod with no cats and a cam. Sick at idle, but probably kills too much of the stealthness of the car
