Catalytic converter or Exhaust manifold

[The Black Pearl]

My TB is in the shop and I was told that a catalytic converter is on order. I thought that the ticking sound on acceleration was the exhaust manifold. Is the catalytic converter and exhaust manifold one piece? Its a 2004 Extended Trailblazer I6.

Thanks

No ,seperate parts.

Just curious, is the noise your talking about a rattle noise? I have an 04 as well and it has developed a rattle noise coming from the engine area on drivers side, I say that because I cant hear it as well if I’m in the pass side. The noise is strictly on acceleration, not when I have it in park and rev it, only on acceleration at the end of first and going into second. I am going to take it in, just wondering if that sounds at all familiar. Any input would be appreciated.

Possible loose exhaust shields.
