Just ordered China Alibaba Kooks 2inch 200 cell cat replica Headers

Actually perfect timing you asked i just got them installed yesterday. The install was perfect and if I didnt tell the mechanic they were from China he wouldnt had guessed. I put the kooks manifold gaskets on vs what the Chinese guys gave and they fit perfect no adjustments modifications needed to get it to mount.

Did it get rid of the chirp?

It's so loud and the sound is all coming from the back I don't really notice it but my mechanic told me that is part of the hemi motors to have a ticking sound and you can still hear it if you listen up close to the front underneath. So it's more of a ticking noise now vs a chirp like a bird.

What size are the headers?? 2” or 1 7/8” or something else? I didn’t see a size listed on the manufacturer’s Alibaba page.
