What catalytic convertor are you running?

[medfordhotrodguy]

I have a 98 LGTw 187k on the clock, my cats are starting to smell and are pretty rusted. I'm looking to see what others have done: replaced with an OEM direct fit cat (Walker or Magnaflow), had a custom setup made, or just throw them away (I can't do this 1)? Include part #'s if you can.

 

Thanks

until they fail completely,

rust though,

fail an emissions test,

i would leave them alone.

 

i have never heard of an after market cat that works as well or lasts as long and the suabru factory cat.

 

if you need to replace,

i would look for a private seller who has used subaru cats for sale.

unless you can afford new suabru cats.

 

subaru cats usually last the life of the car.

although i just had to replace mine on my 98 outback,

but it went into salt water at a boat ramp,

and they rusted out.

i have also had to replace the ECU, brakes and the entire exhaust.

I am also interested in an answer to this question but I have my own issue. the used car guy I bought my brighton wagon from had someone come in one night and cut off the cats from a bunch of his vehicles. my car was one of them, I've had it almost 3 years, NEVER getting rid of it until the shells rots from around drivetrain. but before he sold it to me, he had an aftermarket one put on. it smells horrible. getting a CEL once in awhile for an o2 sensor. replaced both o2 sensors, fuel filter, air filter. I WANT the boxer rumble. also my header is about due for replacement. have around $300 right now. I can weld in stuff myself just need to know what to look for.

if you convert a spark plug anti-fouler into a spacer, you can run without a cat.

 

the rear sensor just checks to see if the cat is working.

if you use a spacer to move it out of the exhaust stream,

you do not need cats.

 

i think one guy even passed an emissions sniffer test with no cats.

but i would not count on that.

 

the front o2 MUST be very high quality, subaru or better.

a cheap o2 sensor on the front can cause a CEL.

the rear can be cheap.
