Is there any california compliant catalytic converter that would fit into 04 TSX and be able to pass Smog Test? What about Magnaflow cat?

 

Well I'll find out if the Random Technology cat will pass smog next June

 

you could always buy a 2006+ oem cat. they have a higher flow rate than your model year

 

magnaflow cats wont last long, but it should do the trick for now

 

I learned this the hard way on my old 2000 Civic Si

 

I recommend this course of action. I have a RT Cat and love it but I don't have CA smog to deal with.

 

Hello, just new here and hope to stay long. Thanks

 

Hello need some info about cat converter and I do some research and queries and I tried it here Magnaflow Catalytic Converter. Anyone tried it here? Thanks

 

i have the magnaflow and it does flow better that the rt. but i don't have a clue about it's smog legality

 

Vin, what do you base that assertion on? Did you do dynos that I wasn't paying attention for, or is this "butt-dyno" action?

I'm happy with my RT but whenever it needs replacing I'm going to be looking for the best-performing solution to compliment my supercharged setup.
