Aerolarri carbon fiber exhaust tips. These are slip on tips that mount with a rubber O-ring on the existing exhaust tips. You do not have to remove the bumper to put these on. I have another set on the car and it has worked great for four months. There’s been no movement falling off or any issues. It looks very clean and I have gotten good comments at the Diablo Valley Corvette show. Originally these cost $699. I will let them go for 425
