My base 2012 has a full after market exhaust system installed. Kooks headers and corsa mid pipe and mufflers. My question is if I want to install the stock manifolds and cats will I need the stock mid pipe or can I use the corsa? Also if anyone has one handy, can you post a pic of the stock mid pipe?
Thanks

It depends on the diameter of the pipes that are currently on there. If the Kooks headers end in a 3" collector, the stock LS3 mid pipe is smaller is will not bolt up correctly. Same with the mid-pipe/x-pipe. If the mid/x pipe is 3" you will need to change it back to the 2.75" (or is it 2.5"?) to mate up to the stock headers.

This guy has good pics:

Also, I happen to have stock LS3 headers w/cats + x-pipe for sale as well (no mufflers, NPP mufflers sold already) in TX if you're interested. PM me for info.
