Hi,

im back, i need to replace the catalytic conv.** I was looking at a universal fit converter at pepboys for 170$, and a direct fit one for around 430$, what is the difference, the universal one seem to need a welding job. Is it the same with the direct fit one??? if i can replace it myself I can save the labor cost, and direct fit one might be cheeper. Do you guys any other ideas??

**code P0420, and the emissions test failed very badly. Also there's a gas smell too. so i assume its the catco.

help.
thx

 

if u can afford it do the 02 sensors while your at it. the direct fit should bolt right on unless someone that had the car before u has welded one on already. as far as pricing look around. have not bought one in a long time but over 400 sounds like alot.

 

thx crabby, but the prob is I live in CA. normal direct fit is around 230-300$ but the california apprevd ones are >400$....!!!

abt the sensors, man im broke...!!! ill check the prices..! do the sensors go bad? the car has 150k on it..!

thanx agn guys.

 

omg the sensors cost ~180$ (2+1)...! i dont think i can do it...! Is it hard to replace it myself later?

 

wow,,, well better clean them instead and it may not be a big thing but does help, sure u can do them in spare time but if they are part of the problem. i think they make a 02 sensor cleaner. i gave mine a light wire brushing to clean em.

 

yeah, the sensors cost ~50$ each for two and ~80$ for the other one. Is it hard to replace them? i mean other than having to get under the car?

 

on mine that hard one was on the starter side. had to take the starter lose to get it out of the way. other than that its, unplug the wire, unscrew the sensor and clean/replace. i only haver two on mine though so the back ones i dont know about. dont have back ones on a 93.

 

I was going to recommend the Magnaflow High-Flow cat, until I saw their price, and your budget.

 

Well, I got the cat from pepboys, arnd 177$ after tax and in store coupon. Welded it for 75$ and passed the smog.

How much is that cat? i think ima gonna need another cat soon....!, the old one was totally hollow. I wonder if theres som'n wrong with the engine, may be too hot??? (i started a new thread on that) Anyways thanx a lot guys, I had only today to do evrything..! n i finally got it done....!
