Cheap Y-pipe and manifolds

My manifolds and y-pipe are getting bad on my 2006 Taco 4L sport. Does anyone have any experience with purchasing cheap Amazon or Ebay manifolds and/or y-pipes?? Just wondering how they are with regards to quality. Any recommendations would be appreciated.

 

Drivers side manifold has the cat as part of it & the y-pipe has a cat as part of it, so it's gonna be pricy.

I replaced the y-pipe a couple of years ago with one from rocauto, so far no problems.

 

Yeah, I see a lot of ebay and Amazon listings for dirt cheap. I'm probably gonna pull the trigger and go for it. I'll be the Guinea pig I guess. lol
Rockauto y-pipe and manifolds will run me $2000 shipped. (CAD)
