Now If you have to run cats then headers with high flow cats definitely gains over completely stock exhaust.
As mentioned by another member, cat less headers or cat delete stock headers passes emissions with Ethanol fuels. I believe most would run Ethanol fuel if it was available.
So perhaps instead of giving people shit for wanting to modify exhausts to make more power you should be asking our government why are we continuing to run all of this expensive emission equipment to clean up shit pump fuel? Clean burning fuels have been around for years that would not require catalyst to pass emissions.

Big battery industry and Tesla will put an end to that haha, but yeah especially the LNG, CNG, natural gas fuels. Do gooders don't want to admit that modern vehicles with modern emissions controls are virtually emissions free. Now they have to create a new "emission" that we breath out so they can continue with their ban. Of course the number varies greatly but ethanol offsets this new "emission". There's no excuse why modern engines should still be 9.5:1 compression.
