Here is the honest deal. My catalytic converter is shot. Smells bad and all. I have no money in my pocket right now so I'm going to have to borrow some to get something put in its place.

I hate borrowing money so I want to keep this as low cost as I can for right now and just get the job done.

I am guessing from what I have read and what I’ve seen on eBay a test pipe will be the least expensive thing I can do.

No shop in my town will touch a test pipe for me... So it looks like I'll have to try getting to it myself with an F***** up shoulder.

My questions are, until I have the money what test pipe would you recommend? And are there any that will give you a place to screw in the rear o2 sensor? What size should I get?

Car specs: 1996 240sx (of course) with the stock ka24de.

And it's going to be louder than I like isn't it?

 

If anyone knows of a good company name/price or anything like that on high flow cats please let me know too. Mine blew out completley so now I'm throwing a rear o2 sensor code. (Code 77)

 

you could try the classified section, on here and other forums, you could probably find a stock one for cheap or maybe even a high flow for cheap....

these guys have some pretty good pricing on cats and test pipes, some more decent prices

 

I made my own with the help of my buddies welder/grinder.

We cut the flanges off the old catalytic converter, went and found a spare piece of piping at an exhaust shops dumpster and welded it together. Some exhaust gaskets from the autoparts store and i was done. If u need the spot for the o2 sensor u can also just drill a hole and buy a bung from the autoparts store.

When mine one all said and done it looked awesome. As good as any i've seen on the net.

 

want to be cheep

take cat of car smash out the inside's of the pipe
done theres your test pipe

 

haha I was thinkin the same thing.

 

Have you also empty the precat ? Cause I empty both cats in my s14.

 

NO WAY man don't get a test pipe, your KA uses a second O2 sensor after the CAT it will only make your fuel mixture weaker, less HP. I bought a catco cat on ebay for $45 bucks 2.5" in 2.5" out best deal ever. Check it out.

 

lol, I have one of those!!!

 

A day late.... I bought a test pipe off of ebay yesterday with the factory o/2 sensor bung. It was the lowest cost that didn't look too crappy.

I love the look of the catco though. I think as soon as I have everyone payed off I'll get the catco or maybe one of the magnaflow (only because I have a magnaflow/flowmaster exhaust).
