Default Any way to "cheat" inspection?

Well I have been on this long debate on whether I should remove my headers or not, and Jim Jr. a JDM suggests it would be better to just put the stock system back on, as they have had problems even with metallic cats not passing. I am from new york and here they do a check through the OBDII port instead of a tail pipe sniffer. I am not sure 100% how this works, but I believe it checks to make sure all the 02 sensors are working properly and making sure your car isnt throwing any codes.... any suggestions on how to pass or even if I find someone to "help me out" will he actually be able to pass me?

I was thinking have JDM give me a tune with the 02's turned on, if I throw any codes I just clear it right before I bring it in, and than after inspection have them turn the 02's off. Not sure if they are going to do this as it involves extra work for them. Maybe when I get it dyno tuned they can just put the 2 tunes (exact same just one with the 02's turned on and the other with them off) and I do it myself.

Thinking maybe I can do something like this

Not sure how NY works compared to PA, but you have to drive your car for a good 60+ miles after resetting the codes before they will do an emissions test, so the simply clearing any codes would not work. Again, this is in PA not sure how NY works. You should find out before going down that path.

I got away with having my o2s turned off on my 2002 gt for 4 years here in az. With newer cars they would plug the obd2 in see no codes and be on my way.

I am going to check on friday with my local inspection center if I would pass as of right now. Apparently you will fail for "readiness" of the rear 02 sensors if they are turned off. I REALLYYYYY just dont want to spend the $270 for the cats and than end up still failing and having to remove the headers after all that

Dude you need to ask your fellow New Yorkers whats the deal. There are several here that live on Long Island that I can think of. Talk with local hot rodders what up, local speed shops, anybody in NY.

Just do like I did and explain your "situation" to the inspector. I didn't even have to ask mine for a way around; he just offered to pass his car's inspection info as my own for an extra $20 right out. Didn't even bat an eye telling me that.

If your guy refuses, then just take your car to be inspected elsewhere.

In New York they hook you up to a computer that is on a State wide database. You can't go to one shop have them do the inspection fail then go to another shop and pay them to pass you. They'll see on the computer why you failed and you're SOL then. I'm not sure about the longtubes.

Why are you worried? You'll pass just fine. Put anti foulers on the rear 02's and make sure your turner has turned them back on. Borrow a OBD II scanner that has the "Emissions Ready" checker on it just to make sure you've driven enough.

Here in GA we test the same way you do.

Visual inspection to see that you have cats.
Scans computer for trouble codes while idling for about 10 minutes.
No sniff test.

My 05 passed just fine this February with Pypes LTs. I did spend the $270 for cats just to pass the test. They were on my car for all of a week then I took them back off. I did have to put them back on to trade it in though.

Forgot to mention, I even had Detroit Rocker cams when I passed. I'm sure they were slinging extra gas down my exhaust while it was idling.

You are not going to pass with an O/R x pipe and your rear O2s turned off. You don't need to take your headers off. You need to add cats, turn on the rear O2s, and get a good tune. Look at my mods. I passed the OBDII inspection. I did have problems with tunes from other companies, but my current tune did the trick.

I agree with 808muscle... talk with some friends that have hot rods that aren't street legal and ask where they get theirs..

Find out EVERYTHING that any visual check will look for. As an example, in CA and some other places, LT's will fail the visual, just like having no cats will.

Be prepared to show any CARB or EO stickers or similar documentation for any of those aftermarket engine parts.

In Oregon the do the OBDII check as well. No visual inspection. I have the stock Saleen magnaflow exhaust, with CATS, running a 302 stroker (well 4.6 stroked to 302) and I pass just fine. First few times I went I failed, and then came to find out that despite mentioning I have to go through inspection, Brenspeed turned my rear O2's off in their tune. They wanted like 20 or 30 to turn them back on, but reminded them of my original request and they sent me a new tune free of charge.

If your rear o2's are off, you will NOT pass a proper OBDII check.

With a proper tune and cats, don't see why you'd still throw codes.

Alright just got off the phone with Jim at JDM and he said my best bet is to just throw the stock system back on. He said yes they have tuned cars with high flow metallic cats, but they 99% of the time turn off the rear 02's on a car with LT's. He said with more and more states getting stricter with emisisons he suggests to just put the stock exhaust back. He said sure we can try and tune with the rear 02's on, but if your throwing codes your than going to have to deal with removing the headers and getting a tune. This car is my DD and I am 18 so I really dont have the time, nor another car, so I am just going to put the stock system back and maybe buy the Ford Racing throttle body to pick up a few hp I lost from removing the LT's.

buy a cheap *** xpipe that will fit your long tubes and just cut the stock cats off and weld them onto the cheap X and you should pas no problem..I dont know if you wanna spend like 130bucks for a new X just to cut up and use once a year.
Thats one thing I like having mine as a toy..under 5k miles a year so i dont get any emission testing done..I get an exempt sticker and dont have to worry about my rear o2 off

You need to call someone else. You are about to waste a lot of time to remove a system that is perfectly capable of passing your emissions.

OBDII scan is only checking to see if you are throwing codes. Use O2 anti foulers and you won't throw any codes. You could even have your stock cats welded up to fit your current exhaust. I bought high flow cats and had them welded up so they are easily removable. The day after I passed I put the straight pipes back in. I had the same Pypes LT you've got.

As for the tune, Brenspeed did my tuning. The ONLY THING they did for me was give me a new tune with the rear O2's turned back on. That was the only change and I passed with freaking cams.
