I am looking for a low mileage cat that has no problems. I need to replace my passenger side cat ASAP. If you have one and are willing to sell it please PM me.

 

used cats are illegal to sell, or install. The oem cats are pretty expensive, like 500.00 or more. I have a spare set...if the money right, because if you try to buy a new cat, theyll ask for your VIN, your insurance...nissan will report you, careful.

 

Whoa.....super helpful info......I had no idea. Maybe a little off topic, but can anyone PM me a place/contact where I can pass inspection w/o cats in the DFW area?

 

Nevermind. I'm just going to go ahead and buy a new set of Crawford HFCs.

 

Are you reading my mind...I thought about going the HFC route myself. I just don't know which brands hang too low or have problems cracking. I heard some of them crack.

 

Well, I just got off the phone with Doug at Crawford and had already given him my CC number when he talked me out of buying them. I had them on before and decided I wanted to go back to OEM, because with all the aftermarket breathing mods I have it sounded like a damn indy car. Doug told me that I had been replacing the wrong O2 sensor this whole time and not to buy the cats. Apparently Bank 2 Sensor 2 is actually on the drivers side, NOT the passenger side.

If you're looking for a quality product and someone that is willing to stand by their product I suggest Crawford. I haven't been this impressed by a vendor for a while. He REALLY knows his stuff.

The Crawfords I had before actually cracked after I put the Nismo exhaust on. They probably lasted 20K miles though. Crawford now has a reinforcing bracket they attach to them in order to avoid this. I wouldn't , and didn't, have a problem buying them from Crawford again.

 

finally!! you found the problem! im glad you finally got down to the bottom of this issue. good luck!

 

No kidding!! I am really hoping this fixes it. I'm sure that an O2 sensor went bad when we switched cats. I have just been changing out the wrong one this whole time. Who would have figured "bank 2" was the drivers side....
