I know my cat is pretty much not legal anymore. I barely passed last year by 1 point. Anyone know of a cheap cat to buy that will just get me to pass emissions? Entire exhaust is stock with all emissions crap still on motor. S4 N/A. After passing I am gonna throw on an apexi N1 until i gotta pass next year. Thanks!

 

I use a magnaflow hig flow cat, they are cheap, but you will have to get the flanges (from racingbeat or mazdatrix) and weld them to the cat.

 

no, not a high-flow cat, just something cheap that is supposed to last like a year or something...does autozone even sell cats?

 

yes they do they have direct fit its like 100-160 i dont remember
all u need it for is a little bit right? have u tried ebay?

 

yeah, just for a month or so.

 

auto zone, generic cat. I think i've seen em for 60...

 

the 60 dollar ones dont have flanges (i got that one and welded it on for inspection) the direct fit(bolt on) are more
