Maybe yes maybe no. They'll fail you if they do a thorough visual inspection anyway. Keep in mind cats can become less effective depending on how you drive, so in 5-8 years it could trigger some check. Just keep the stock dp and swap it back on when the time comes. People who live in strict emissions states and sell their stock dp lack foresight.

Worry about it in 5 years

These will pass the OBD, but won't pass visual if they look hard at it.

So I should keep my stock one to gouge some sucker later on?
