Default Kooks x-pipe options

Does Kooks make a catted 2.5” x pipe or just catless? I found the catless one but the only 2.5” catted one I could find was for 05-08 cars and I need one for my 2011. I don’t want to go 3” because I need it to fit my 2.5” Borla axle back.

My set is quite a few years old, 3" catted in the front and necks down to 2 1/2" in the back:

Kooks x pipes are 3" but they neck down to 2.5" before the mufflers unless you get one for a Z06/ZR1. This is the one you want https://kooksheaders.com/exhaust/cro...onnects-to-oem. You'll notice it says 3", but also says connects to OEM. And in the pic you can see where it necks down before the mufflers

Nope, don't want to sell them. I bought them used off a fellow forum member about 5 years ago, they are still on the Corvette and barely visible in the photo:
