I replaced my stock cat last year with a Monza to pass smog. It worked but the cat has crapped out on me this year when trying to pass smog.

I need a new brand. What are you guys using to consistently pass smog with?

Stock.

oem is the way to go

I barely passed using a new high flow cat by dynomax. If you use a high flow cat I would reccomend using that garanteed to pass stuff.

Magnaflow/Carsound high flow cat. But only because the stock cat had crapped out.

The price for a replacement cat from Honda...almost $600.

That's all good and everything and I'm sure they are handy when passing smog, but who has that kind of money for a cat??

Sounds like my best bet is Magnaflow, from some responses I have gotten and other posts I have read.

i don't know about cali, but i heard on the east coast these are the cats they are using.



LOL, just having fun.

I used a Random Technology direct fit catalytic converter which I installed in 1998 and passed ever time till I stopped driving the car in 2004.

1:keep the cat you have there
2:find 5 other honda owners in the same obd-compliance as you
3:ban together and buy the cat (600 / 6 = 100 each)
4: keep the car you have already on until its smog time, then install the oem cat
5: pass smog
6: remove and hand to another friend that needs to pass smog
7: repeat as needed, and since the cat gets used for only 6 days per year, it will stay mint for a long long time

That's a good idea, but I am a bit of a loner with all of this. Never really was in the 'scene' that much, especially now that I moved to Cali...its just sort of a hobby for me....so I seriously do not know one other person out here that works on honda's that I can hang out with...

i know, sad life...

Same here. I got a Magnaflow because the OEM one needed to be replaced. I got mine off eBay for around $40 and just got the stock flanges welded on. Passed smog just fine, even at a Test-Only center.

oem cat with a 91 dx exhaust manifold!

SiRMike

This is what I do for emission test up here in B.C., Canada.

I run a test pipe 364 days a year, and the one day that I need to go through and do my emission test, I put my oem cat back on...then once I pass and get home, off with the cat, and back on with the test pipe.

Stocki have some straight pipe that was given to me but its always good to keep the stock one around.Try making a a WTB post and see if anyone has a good stock one for sale.I'm sure it'll be cheaper then $600.I paid $50 for mine.I would let you borrow it but your in so calGood luck man.

What car/engine do you have?
I have a Magnaflow hi flow cat, never smogged it but before you buy one I've heard mix reviews on the Magnaflow cat. It's sort of a hit and miss cat, some go bad almost instantly and some last a long time. I've got lucky and I've had mine for over a year. If I was you I'll get a Magnaflow hi flow cat, if you don't pass put on two. Get it on ebay.

professor poon

OEM rsx-s cat custom fit. Got it for 65 bux and its way bigger that the oem one.

TEST ONLY

OEM is the only way to go....

axtran

i had a magna hi-flow put in using D16Y7 engine, got nearly zero on NO and CO% readings, extremely LOW HC. so, i'd say its a good cat.

this is california too, and i ran it inside of a '92 DX (stock D15 and not BARed) and it passed just fine.

TEST ONLY

Sounds like you did great, and you have a really healthy engine......
