So I put long tubes on my car a while back along with an off-road h pipe. I was given a tune by Brenspeed that the guy assured me would fake out the computer to not throw a check engine light. Everything was fine, but i got to thinking, would this also allow me to pass inspection when the computer scans my car. I checked tonight at work and all three of my cat related readiness codes were incomplete. So even though i can inspect the car myself, it still will not pass since the computer scan my car's computer and those readiness codes are not set.

If i got a catted h-pipe, would those readiness codes set? I have heard that with long tubes, the sensors or cat don't get enough heat and therefor still sometimes set and a check engine light.

Anyone out there who has long tubes, how do you get your car inspected?

look into spark plug foulers. they pull the o2 sensor out of the exhaust stream so the computer thinks the car has cats. make sure o2's are on and you drive atleat 50 miles
