Before selling my 2005 GT, I put back the stock axle backs on it to reuse the 1st Gen Sport Corsas on my 2011 GT.

I called them 1st Gen because they used to be almost perfect cylinder and although the p/n is the same as current 05-10 Sport Corsas, they have a different shape now.

Here is a pic Stock vs. Corsa:



So what do they sound like ? Well, they are louder than on my 2005 and a little more high pitch. I personally prefered the sound on my 2005 but it still sound pretty good.

Now, I just hope I will pass sound test when I track my car next summer; my 2005 did but this one

Here are 2 videos, you can judge by yourself

Not too bad at all!

 

Sound good! Your lucky no one stopped and grabbed your camera haha.

 

I had a hard time finding it on the side of the street when driving back and there is no sidewalks there

BTW, retrofitting these mufflers required some modifications by the muffler shop I went to.

Would I doing it again ? Probably should have sold my 05 with the Corsas for a little more and bought the 2011 Sport Corsas for this one. Oh well
