For all you JDM ITR Header people, what cat are you using? I've burnt through 2 Carsound Cats in 1 year and now I'm due for smog. Does anyone know if the S2K cat has the correct size collector flange?

Thanks!

 

o man i remeber smog when i used to live in cali but now i live in nc no smog here so tight but i think the cats size is different maybe im wrong

 

you use the jdm itr cat or just get a 2.5 inch flange and weld it onto a stock cat even tho thats illegal but if you do it yourself no sweat

 

im using the itr cat with mah header....
