I have them...
They sound great. I bought an '07 coupe with them installed, personally I really like the sound, low and throaty.. 
For the money I don't think you can go wrong, all you're really buying is the sound; it makes a 'vette sound like it should from the factory.

Are these really worth getting for <$400? Do they last a few years, being there not the stainless steel made? I'd like to get somesound improvement, but I don't want to drop the 1.2k for the other brands. I'd rather use that money for a tune from ECS.Anybody want to chime in?

drone - solution ( for me )
My 2007 is an A6 – clearly more prone to drone with aftermarket exhausts.
I changed to the Flowmasters ( Quad Tip ) and shortly thereafter changed the stock H-pipe to a Corsa w/dual resonators – to reduce the volume and the drone.
On ‘general acceleration’, the background harsh tones I heard with just the Flowmasters ( others clearly are NOT bothered by this or there is dramatic car-to-car variation ) is reduced at every combination of RPM and throttle opening. Under general acceleration, at 1500-2000 I hear the deep tones I was looking for, and much, much less of the ‘other’ tones ( noise ) I wanted to reduce or eliminate. The ‘good’ notes are still there.
The H-pipe has essentially eliminated any drone in the RPM range critical to me: 70 – 80 MPH cruise ( = 1550 to 1750 ), where I spend a lot of my highway travel time. Traveling at this speed is now a pleasure.
There is still a bit of what I’ll call ‘drone’ in the 65 MPH range. Not nearly as loud \ noticeable as before - but clearly present. I can drive around or tolerate this.
Let me try to define \ describe how drone manifested itself to MY ears in THIS circumstance:
If you were settled in & listening to a flute or a harp solo - and someone else on the stage with a Tuba started to blow a single, low note – you might still be able to hear the flute that you were hearing before, but your enjoyment would be substantially reduced by that overlay of the loud, low, single tone.
To me, this is analogous to the issue of drone for me in my C6. Meaning: The Flowmasters allow much more of the deeper & distinctly V8 tones I wanted to hear when I changed the exhaust. But also, simultaneously, they generated what I found to be a harsh, discordant note - something I found very obnoxious. This was apparent on acceleration and at almost any steady throttle opening.
The Corsa H-pipe reduced the overall volume, but only a moderate amount. It is clearly still louder than stock. ( As I wanted. ) But it is in no way obnoxiously loud.
The H-pipe virtually eliminated the drone in the highway cruising speed range I really cared most about.
The H-pipe reduced the drone on general acceleration to the point that it is almost no longer noticeable. And much more enjoyable. To me.
The distinctly V8 nature of the exhaust note is now quite apparent & relatively ‘pure’ under most conditions. More melodic and harmonious, rather than discordant or dissonant or grating?
Hard to describe, and ( clearly ) people hear differently & are (in-)sensitive to different frequencies & volumes of exhaust tone.
I bought both the Flowmasters & the Corsa H-pipe from PFYC.com.
So again I will offer a ride to anyone in or near the Atlanta area. . .
If you do want to arrange a ride, please PM me.
Just my 0.02 gallons worth . . .
