My question is, will me car not pass smog if I do?

No it will not pass smog. Replacing the OEM header with anything else will not pass.

Is that going to cause me problems?

How difficult would it be to swap them?


My car is relatively new, 2016 with 17k miles.

Yeah, that's the drawback for me too. I'm planning to get Tomei uncatted instead. We have two cats, so you don't have to worry about the smell. Once you do the Smog Check, just slap back the OEM on. It's a hassle, but you only gotta do it once every 2 years.

It's not particularly hard but you will have to get under your car. It will help a lot if you have a lift. If you're lazy like me you can get a shop like Elite Performance or The Racer's Line or Mann Engineering to do it for you.



You actually get 6 years the first time after purchase of the car new. So for a 2013 you have 2 more years to go, for a 2016 you have 5 more years before a smog is required. :)

I have a catless header, and the car smells funny on start up. It goes away once the second cat warms up though.

Just to make sure tho. Since we have two cats, there wouldn't be an obvious smell if I change my headers right? Like it would pass the Smell test?

I was told by my friends that it should be fine, but some said it might be worrisome...
