I have a set of Kooks Headers that I took off my '12 Silverado. They are 1 7/8" primaries and are ceramic coated. The y pipe is for the 6.2L withe the 3.5" ball and socket connection to the cat back. It also has cats but they starting to smell a bit. I had to dent the #1 primary to clear the factory plug wire for the #3 even with it trimmed. I also had a lot of trouble getting the clamps on the y pipe to seal and the ball and socket collectors kept coming loose so I welded all the connections on the y pipe. The welds aren't the best but they seal. These will require welding to install. $300 + shipping or local pickup in New Hampshire
