Went over to a local Vette/Porsche nut's house to utilize a lift to make the swap quick/easy. The install was simple and went w/o issue. The Extremes are noticeably lighter than the stockers (Corsa says something like 5lbs)... I'd say they're close to Z06 Ti weights, but I didn't weigh or anything. The Indys and Touring are very very heavy, something like 80lbs. Tip alignment is very easy, far better than Corsa Indys which have 3 joints.
As for sound... I'm not sure how Corsa does it, but the mufflers are nice and mellow at idle, OEM silent at cruise, and have a great loud sound at part-throttle north of 2500 rpms and WOT. Seeing as the design is basically a straight-pipe with a muffler on the side I guess vacuum or something pulls the sound waves in at lower rpm. I was suspect of Corsa's no-drone claim, but it's 100% true.
I'm very very happy w/ my decision, she sounds like a sports car now. If I had to describe the sound it's basically Borla Stinger tone with a more refined note to it and no drone. For years people have been asking for Stingers w/o the drone and Corsa has delivered. I'll probably break down and buy AR headers for her one day, but for now this will do.
Just a small portion of the garage setup
All done
