Long tube headers tune question

Anyone make a tune for long tube headers that will pass emissions? Live in NOVA.

I thought long tube headers were pretty much a no go with emissions as is

I thought your okay as long as you are using high flow cats? I live in NOVA as well... I have 2 friends with long tubes one has high flows and one has no cats and both need inspection soon, I could ask them I guess

I heard that the cats are fine for sniffer test but the computer doesn't like them and throws a code of not ready. I'd love long tubes but I have to pass emissions.

any good tuner can get you through emissions, you just need all emissions to read as "ready" and you'll be good to go, but this is only for states that do is OBDII testing only, you won't pass an actual sniffer test or visual

Most states only allow 2 "not ready" codes to come up. Every car that is tuned is going to show 1 no matter what. Now the other one that pops up will be when the rear o 2's are disabled. Which they will be with high flow cats and longtubes, just *** with a offroad mid.
