I need to replace the Catalytic Converter on my car. I am thinking of buying the converter that can be welded to the existing pipe.

There is the option to buy the converter with the upstream and downstream pipe. This is of course expensive - about $350-400.

Any suggestions?

I would like to know how easy or difficult it is weld the catalytic converter. Does this require disconnecting the pipe from the turbo? Is it reliable?

 

if you can't weld then take it to a local shop that will work with cats. some shops wont though. It is safe and reliable.

 

I don't know if you have the existing pipe or not, but when I replaced my exhaust, my stock exhaust was severely rusted, it might not be a bad idea to get a look at the whole thing and see what kid of shape its in. FCP sells the downpipe with cat for 300 bucks, and the cat back for 240. Just an idea.

It may end up costing you more in the long run to have it welded, especially if the exhaust is very old.

 

I have one for sale...Conical flanged from a 95 T-5R

 

you mean you have a downpipe forsale with scrap metal attached to it

 

Call it what you want but I have a fully functional downpipe attached to a factory OEM Cat in great condition for sale.

But i know what you mean....I wish all these California laws were not in place, I would remove mine.

 

It's actually against federal law- not just california law- to sell a used cat for reuse. That's why you're selling a used downpipe with a piece of scrap metal on it

Keep in mind... New aftermarket converters are NEVER as good as originals... they have less catalyst in them, so they won't last as long... it's an exception the government made to make aftermarket converters more affordable, so that people would replace them. A large factory converter can have as much as $500... or more... worth of platinum and rhodium in them. And when you take your original converter out, make sure to take it to a scrap metal yard... they're actually worth a pretty good bit of money.

 

Thanks for all the tips. I searched on Ebay and found one. It has 3 O2 sensor ports. My 850 has only 2 ports. What's with the additonal port?

So you can run a wideband AFR!

 

Good info gilber33, thanks

 

YUP! I don't really know if that's the exact purpose for the third bung on that dp, but since you only need two, it would be a perfect time to install a wideband AFR.

 

it says a 3rd O2 port so yes, you could run a wideband gauge. just get an O2 plug if not using it. If it is smaller than an O2 port, then it could be used for an EGT sensor.
