Hey hows it going, my 01 XJ has been giving me a P0432 code often assocciated with the mini cats that are located right off the exhaust manifold. I had a mechanic check it out and he said my cat is definitely bad.The car has 110000 miles on it, is completely stock and is getting around 9mpg, which is absolutely terrible, I need to get this fixed fast so I decided to see what the dealership would charge for the part.What a mistake that was. They were asking 1100 just for the part. I'm finding them on the interwebz for around 350. There's just too many brands though, what would be your suggestion?


Thanks in advance

 

Get aftermarket.

Maybe even try NAPA or something.

You may have bad cats but remember the 02 sensors are what gives that code.
I had the same issue and replaced the two rear sensors and have not had the P0431/432 codes inn the last 5K.
Good luck

one of the eleventy thousand o2 sensors on his truck could indeed be the cause, but if he's already had a mechanic take a look, I'd lean toward what the mechanic suggests.

Not saying every mechanic/shop knows what they are talking about, but at least they've seen the truck first hand.

 

Yeah, the guy i brought it to had been working on jeeps his entire life. I trust his opinion. He'll be doing the install, I just need the part. I would like to go aftermarket, since I can't justify spending 1100 dollars on it. Is there some well trusted brand you guys often use here on the forums when it comes to cats?

 

Most here always talk about cat-back systems, so usually cats aren't replaced.

Unless you are going for all out performance, I'd just get whatever generic replacement your local Napa has on hand.

 

Get them from NAPA its that simple. gl

 

So just a recap, all I want is my gas mileage back, no check engine light and a smoother ride. A 250$ cat will do that as well as the 1100$ dealership cat?

Thanks alot for your help guys

 

magnaflow cats are reasonably priced, try them

 

whats "resonably priced?"

If they beat Napa that'd be better I'm sure.

I'm not exactly sure why the dealership charges $1100, but it can't be too much different from any others.

I'm guessing flow rate is the main difference.

 

3-way cat with 375ci capacity for 100 bucks

plus its a high flow metallic substrate cat, so the matrix wont collapse like with the ceramic

 

If the NAPA one is really $250 this would be by far the best deal.

Sounds like it flows well, too.

Thanks for your help guys, I actually found the whole assembly at a autoparts store for a cool 250 bucks. I'm going with that and have the operation done saturday. I'll let you know how it goes.
