hey whats up i need some help i thinking about doing an exhaust on my 93 honda civic coupe but i want to do an exhaust that can pass emisson for arizona. I want to do a cat-back exhaust but i'm have a hard time finding one that will pass emissons. But another option i was thinking about was doing a 2 inch exhaust piping with a stock cat and canster. It would be cool if you can tell where i can find a cat-back that will pass emissons or my option i came up with will pass emisson.

 

I'm not sure what the laws are in Arizona but here in California, there is no emission levels for exhausts, all the state cares about is dbs. So anything under 95db is good enough. I'm sure its the same in Arizona since California has one of the most strict emission regulations in America....ugh I hate it.

DB = Decibel

 

Max DB in ohio is 79 DB. i'd agree that AZ laws are prolly similar to california's... prolly a lil less strict do to the populations density differences (# of cars as well)
