Arrived quickly and sounds amazing.

I watched several YouTube videos of CORSA exhaust installs on C7 Z06 Corvettes before I purchased and installed. Pretty straight forward for a DIY. I have a C7 Z06/Z07 A8. If you're only doing the over axle (No Mid-Pipe) you don't have to remove the tunnel plate. On the A8 you will need to put the car in Manual to get the drivers side factory piping to clear during removal. The instructions say Neutral but, mine wouldn't clear until it was in Manual. Everything was easy peasy. With the tip assembly being welded together, the alignment is super easy. I went with 5.5" off the crash bar instead of 5" to have the beautiful Diamond Black CORSA tips on display.
