    I do have a question tho. My plan is to run cat less for 99% of the time then put the factory setup back on In order to pass inspection. But will I still pass if my rear o2 sensors are turned of. Ill put a bung plug(hehe) or big bolt in we're the rear 02 hole is. Will this pass inspection. Or do I have to have all 4 o2 sensors working?
    You should be able to pass inspection with the two O2 sensors turned off. The only reason to have the two rear sensors physically on the pipe/or cat is the outside chance an over enthusiastic inspector crawls under the car.

    Cool. I kinda figured but your reply makes me confident it won't be a problem. Plus I've been getting my cars/trucks/motorcycles inspected at the same shop for at least 8 years. And in the past they have let some very obvious fails just pass.

    Not yet. My cars interior is all ripped apart right now. I'm having some accent pieces hydro dipped(I got another thread going about it in the appearance mod section). So I'm trying todo just one thing at a time. I know the exhaust is completely different than the interior, I just wanna get this(hydro dip) done first.

    Ill prob do the cat delete next week, only problem is the shop I go to is about an hour from were I live now, so it's basically an all day ordeal for me.
