From what I have read the extremes are 5 db louder than the sports. I have the sports with headers and still no droan. I personally would like a deeper American muscle sound. I will prob switch to the Borlas Touring from Jimmy at Atomic Autosports. Might have a little droan but that is ok with me.
I have Corsa Sports. With the stock exhaust manifolds, I thought they were a bit on the quiet side for me. Then I installed Kooks headers, cats, and xpipe. The Corsa sports now just scream at WOT, 3000rpm and above. If I didn't go with headers, I would lean towards the Xtreme. With headers, I am happy with my Corsa Sports. As always, it's tough to tell you what is too loud or not loud enough. No drone at 70mph though. Music to my ears.
Well, I've had the Corsa sport on my first C6 and was exceptionally happy. #2 was bone-stock. #3 is going to get a few add-ons to compensate my emotions and that I could not justify the $$$ for the ZO6.
But still need the noise to wake up the neighbors on the way to work!
I just had Corsa Sports installed the day before yesterday. The place where I purchased and had them installed is about 100 miles from home so I was able to have a pretty good ride at interstate speeds and noticed no drone. They are just about right for me. Sound pretty decent at idle and under acceleration, but not too loud.
Does anybody have first hand experience with Corsa Sport AND Corsa Extreme?
I'm ordering in the morning and need opinions. Highway driving @70 is the critical area. Are they equally 'drone-free'?
You didnt say whether you had a manual or A6. In any event, Corsa guarantees NO drone for the Touring and Sports providing you use the complete package system. The Extreme's do not carry that guarantee. If you have the A6, its highly recommended to use the Corsa H-Pipe with the Extremes to reduce noise and drone.

I didnt think the Sports were too quiet after replacing the stock exhaust! I was pleasantly surprised after adding Kooks headers that there was still no drone and made little sound difference at idle, freeway cruising and below 3500 rpm. However, above 3500 rpm, it sounds like a racing car!
