Does anyone remove/cut your Gasoline Particulate Filter (GPF)?

    GPF's negative effects are larger than positive effects. Especially in short trip.

    That might be slightly true in a V8 or V12 engine that's been run at max rpm on a race track. But driving a little four cyclinder Toyota around? There's no way that's going to be an issue.

    I don’t think Prius and other Toyotas in the US have them as far as I know.

    In any case, it is illegal to tamper with any kind of emissions systems, not to mention that the car will fail the emissions inspection or test.
