I bought the Xtremes and have enjoyed them when weather has permitted. They are actually quieter than I expected while idling and cruising. They come to life when on the gas but I can't tell how loud they are from inside the car. I'll have to let a buddy do a drive by so I can listen. I am happy with them. ZERO drone even when trying to lug it or find an RPM to create it. The 4" tips look pretty mean. So far so good.
One question: Is it important to re-torque the clamps? Will they loosen up that much too cause a leak or problem? Just asking because I do not have a jack that fits the vette and I would have to work something out.

Supposedly Borla has recently redone their exhaust (including the Atak) to eliminate any drone. This is according to a new video comparing their 3 exhausts (Touring, S-Tyle 2, Atak).
I have no personal experience with these.

A comment to this forum from David Borla himself help maybe?

Like many, undecided between Xtreme and ATAK. I love driving with the top off and I can barely hear the engine. From what I gather, on a stock car, Xtreme isn't really loud until WOT. ATAK seems too loud for some. In Louisiana, I can hear pickup trucks meters away over my car. My only concern is being a good neighbor in the mornings and drone. I've watched videos, etc. and frankly, they all sound good (even stock); you cant't really replicate the sound on video. So the questions are:
1. On stock config. with M6, does anyone regret going ATAK?
2. Is there a dB chart anywhere for Corsa and Borla? BB provides a direct dB comparison on their website.
3. Is S-type louder than Xtreme?
I've pretty much read all the threads. Just looking for amplifying info.
Thanks!

Borla has a free app available at the Apple App Store.
I bought an S-Type II, and the app connected to my stereo sounds true. You can also easily "A/B" the ATAK vs other Borla systems.

Any low-restriction exhaust will generate drone/resonance with the interior of the car. The drone, as we call it is not completely controlled by the muffler. It is the exhaust's sound (vibrations) interacting with the resonance frequency of the car (which is a composite sum of the resonances of all of the materials making up the car). Hollows and chambers create amplifications of these resonances like a speaker box.
While I love the sound and will not change these Xtremes, don't let anyone tell you there is no drone.

No one else can tell you which exhaust to choose. You need to hear them yourself, both in the car and out, in person. 
I have a coupe with the NPP exhaust. I just use it for pleasure trips.
Here is my experience:I have removed the fuse and get drone at the mid range rpm's. The "trunk area" works like a speaker box amplifying the sound.
When I use the cargo shade it helps very much.An NPP with a switch to turn it on and off, and a cargo cover, would be ideal for a daily driver, in my opinion.

Borla S type 2 ... Awesome - insane sound - Very noticeable on " WOT " but that's what we want...Header package kinda helps also !!!
My decision was bang on...Atak would have been " way " overboard ... It's all what you want though ... Cheers

I just bought an ATAK for my 05 and my father in law has the Corsa Extreme....his is louder. Not significantly but noticeably, inside and out.
IMHO, his is slightly more raw/harsh than mine but I like it as much as I do the ATAK.

Installed ATAK; awesome!
As you know, I was debating between XTREME and ATAK. Went with ATAK since I got the impression, from most, that it was a bit louder. The Borla Bondurant videos helped. ATAK is not ridiculously loud; it's legal loud. Yet, noticeably loud. My 6yr and 4yr old loved it. Yes, they like race cars. If you want a race/muscle sound...ATAK is it. Finally, I can hear my LS2 with the top off. It did take me forever to remove the stock exhaust...get some help. The Borla videos, and references to ignoring the stereo, addressed exactly what I was looking for. It changes the car. I worked hard for a Vette; I don't need a stereo!
Thanks to Marylandspeed.com, and David Borla. Dude...my kids have seen your Bondurant videos like 20 times!

Good choice...yeah, I watched those videos a million times, too, before I made up my mind. Ditto for MS and DB, they rock!
