I'm with Jack... no clue what those are. Stock cats will have the Nissan name and/or logo on it somewhere. And I know it's been a while, but I don't remember the stock cats having 3 holes in them for sensors... The cat itself definitely looks stock-ish, but the piping and the setup doesn't seem stock overall.

 

not stock for sure..

 

well I think I may have just scored crawford hfc's for 100 shipped.

the owner of them just replaced these with crawfords!

 

very nice.

 

from the looks of it.....I def think it was off a turbo'd car because the top sensor is a EGT sensor or exhaust sensor and the bottom one appears to be a wideband sensor....like AEM.

 

yeah some FI car for sure, they look like they are pretty beat up from the outside, check to make sure everything is solid when you get them.

 

its just going on temporarily.....! just need them to get by for alittle bit

 

Yea those are crawford hfc's ill take those lol, new car Chris?

 

do you want them before I install?? I will trade you for your stock cats??

yes I will have a Newer Tahoe or Yukon hopefully by the end of the week..going to look at 4 over the next 2-3 days.

 

Oh yea long as the cats in those are still good

 

honeycombs look like money!!

 

crap if James falls through I want them

 

All yours man, I'm officially a poor person lol

 

 

The block looks nice and clean, can't wait to see future updates. Makes my upgrade seem crapy, lol. Just installed the JDM battery cover.
