I installed the Sports on my z51 6-speed a while ago now. From stock to the Sports it dynoed at an additional 11rwhp peak in 45 degree weather using a dynojet. This was on the same day and after a 20 minute driving stint. Take it with a grain of salt though, most people will tell you that exhaust kits are for sound on these things.

10-20% is
Heck at that you should buy 2 sytems for an 80HP gain 
8-10 more likely

Now that I am over the flu and can reschedule my dyno runs I will be able to answer the torque and HP gains for a CORSA Sport with X pipe...so we don't get into ANOTHER thread about dyno testing this applies to my car only...so I can present a pre and post dyno run for the CORSA exhaust...

I don't know that I have any HP increase with the Corsa's (and don't care), but I sure got a better exhaust sound! Not too soft .. Not too loud!
I did not want my ears stung by Stingers or pierced by Bullets!
Now when I install the LG Longtubes I WILL look for more power.

Thanks to all who replied. I felt that those numbers were high but admit I've been away from the performance thing for awhile and wanted to check what I was told by those "in the know" and not just talking BS for a sale. Thanks again. Now I will go purchase but not from the dorkweeed who qouted inflated numbers.

Even though they don't provide much gain by themselves, they "set the stage" for allowing other mods to work better (e.g., headers, h/c, f/i). The stock exhaust isn't bad, but anytime you can remove a bottleneck, it's a good thing.
