I'm searching for a catalytic converter for a 99 honda civic si and apparently every cat i see on the web is non legal in California. Anyone knows a site where i can get a legal California cat?

 

do you want a performance cat?
if not, just buy a OEM cat from honda.
or check out the honda-tech market place

 

I'm probably going w/ OEM considering that i herd performance cat. converters might give u problems down the line

 

if your going OEM just go check out majestic honda.

 

Apparently their cat converters are non-California legal lol.

 

it does not have to be of the same year.
just get one thats 99 to current.

 

so i can get a cat converter from a 2006 civic and still fit my 1999 ?

 

yes. pipping might need to be added or removed but it will still work and fit.
but a cat is a cat. doesnt matter if its from 99 or 2009

 

well I'm looking at the site for 2009 and it shows they only have for 49 states except California lol

 

piece of sh*t. well just a an Ex cat from 2001.lol

 

Hahaha yeah i know that's why i posted this since everything i non california legal lol. U think the ex model will fit on my si?

 

try a junkyard, im sure they will have one.

 

and Ex will work and fit on an Si.

junk yards are not supposed to sell cats. its against the law for some odd reason

 

No.
When you go to Majestic Honda to browse their catalog, when selecting your car you must put "KL___" instead of "KA____"
KA is 49 US States, KL is California.

The KL catalytic converter is supposedly different.

 

yup.
but im sure they are the same.

 

get a magnaflow cat that is california legal and cheap..bought mine for 149 and it helped my pass Bar

 

Oh, so those will pass?

I researched on it for someone before and found out that they are not C.A.R.B. approved.

If they'll work, OP, you should get one. Here's the link to a good deal.

i always heard that they would not pass.
guess i was wrong

 

"california legal = no"
guess that wont work

 

AHA
I knew it!
lol

 

magnaflow has 49 state which is a NO NO for california but they also have California Approved which DOES come with a Carb# stampped on the bottom...u just have to find the California approved one...i was told this by the state ref. that they ARE LEGAL just the California OBD2 approved ones

here is the one i use to pass Bar with http://www.car-sound.com/02product/d...niversal=46034

its for an Acura but im pretty sure you can use that for your SI

his PDF file shows u that the 46000 series magnaflow cats for OBD2 approved for california is ok to use on Hondas

 

Any luck? I'm looking for the same thing but nowhere sells them. I went to a couple of muffler shops and they said they don't sell any 99 si cats either. I think I have to check the dealerships next.
