Sr20 s13 coupe NEED TO PASS EMISSIONS
 

I live in Arizona and have a s13 coupe with an SR20 and am desperate need to pass emissions I have a full 3 inch exhaust with no cat and Was wondering if I put a cat in or had to just get a whole new exhaust just so I can pass and what else will help me pass?

Or if you know of any other ways I can pass ;) I have cash if anyone can help me out getting this car registered, THanks.

Every car is different. It's almost impossible to tell if your car would pass by just throwing a new cat & exhaust on. You could be running hella rich, spewing all kinds of crud out the back & we would never know. Maybe try contacting who ever did the swap & ask if he knows a shop that will "pass" it. Better odds with that than asking on an international forum...

Well of course it being a 240 and with simply just an sr it was done in a garage so no shop to call but I was more thinking of can't you put denturede alcohol in and that helps?
