regarding....
Whether you can still be legal or otherwise? You remove one emissions component from your car you can be failed. It just depends on what you want to do.
With a OBDII PCM you cannot remove any emissions component w/out getting a SES light. Best thing to do is to find a tuner who can delete the emissions codes from your PCM. If you want to remove your cats for LT headers and such you can still keep your EGR solenoid plugged into the PCM and get 02 sims for the rear sensors and a blockoff plate for the EGR. I think there are other resistors you can use for the AIR pump, but not completely sure.

I don't care about emissions. We do not have any emissions at all. I just want to know everything that I can remove. Air pump, egr, cats ect. I am putting long tubes on Saturday and I know there are instructions on exactly what you can and cannot remove.

Thanks

the emission systems include

EGR
AIR
CAT

deleting these factory systems are not legal anywhere in the USA. They keep your car road legal. You may not have emission checking but if you drive your car on the road you have to keep in mind you run the risk of being issued a citation or impoundment if the cop figures out you have no emission systems. I know its dumb I know its not likely but just letting you know.

The first part of that statement is true but the second part may not be.......if you are from out of state I am pretty sure there is nothing they can do as they are state run programs. In Illinois where they only have 15 or so full or partial counties that have emissions testing out of the whole state, the vehicle code strictly prohibits those counties from giving citations for emissions to anyone that lives outside the effected counties

Do you have inspections? If so on the bad side even though you don't have emissions you will still be checked to see if all emissions components are present. On the good side most techs have no clue what they're looking for nor do they want one. If you really want to stay legit for at least for state inspection you can have a dual cat y-pipe made for just that occassion. They can be costly, but it's worth it at least for me. Or you can just find a station that doesn't care and pay them a little bit under the table.

I have heard different. If you are licensed in a county your licensed in that state and even crossing county lines they can still give you a ticket. Its like saying if you speed over county lines they can't give you a ticket unless its the county's PD. Same goes with pretty much any citation. At least thats the way it is here in Ohio.

Technically you can fail emissions inspection if you have aftermarket emissions parts. In reality most inspections just check for gas cap, Catalytic converter and computer codes to see if there are any AIR or EGR malfunctions. Oh and BTW you can be put in jail for bribing inspectors

A little hard to prove unless it's an undercover "shake down" sting operation. The law will go after the shop more than the customer. Any state inspection shop has a sign of the exact fines/jail time the shop faces if they sway. There are those out there who don't care and would rather have the money.

If nobody cares, there is nothing you can't remove. You will have to get re-programming to get rid of the trouble code reporting, though.

Sorry to get off topic but,
If you ever run across some hard info on exactly what the laws are about emissions on out of state cars in Ohio I would really appreciate you forwarding it to me as I have a obvious need to know lol. I think the Power Tour is going through Ohio next year and even though I don't think I can make it this time you never know! As far as personal experience I have never had a problem cruising with my car the last 21yrs in Illinois, Iowa, Michigan, Indiana or Wisconsin.

You can start here:
http://www.racingbeat.com/emissions.htm

SEMA should have info as well.

I think you will have absolutely NO problem as long as you don't make an extreme specticle of yourself in front of a cop.

Ok sure no problem... I will start with the facts sheet for the Anti tampering law implimented in 1993

http://www.epa.state.oh.us/dapc/eche...tamper_law.pdf

Then you can go through the FAQs for Ohio E check

http://www.epa.state.oh.us/dapc/eche..._info/faq.html

Then you can go ahead and sift through the air pollution control page

http://www.epa.state.oh.us/dapc/regs/regs.html

And if you want more come check out 224.20-765

http://www.lrc.ky.gov/KRS/224-20/765.PDF

Now you want to know something? Im just giving a friendly warning to people that strip their DD of all emission control devices. I really couldn't care less if someone gets a ticket for not having a catalytic converter or what not. 1 thing though if you arn't sure if Im right or not then do some research before trying to call me on it.

As far as out of state vehicles I quote...

Just what is illegal in Ohio?
Under state law, it is illegal to sell, lease, rent, or operate a vehicle in a tampered condition. Removing a pollution control device from a vehicle is illegal. Likewise, selling or installing a device that would hamper the effectiveness of any vehicle pollution control system is prohibited. Individuals--as well as car dealerships, muffler shops, and repair facilities--are prohibited from tampering with a motor vehicle. If you know of someone who has tampered with a vehicle, you may file a complaint with Ohio EPA.

will the cops bother you about it? Probably not but why risk it for a DD?

Heh I think you took that the wrong way lol.........I asked that question because I have been tring to find out about other states for awhile now for obvious reasons.


My car has been like this since 86 and like I said I have never been bothered in several states (and yes the car is driven).We have done the Power Tour for a couple of years and that got me thinking since there are alot of cars like mine on the tour and they have gone through a lot of states that have tough emissions laws I have never heard of anyone having a problem.

It is unlikely that you will have a problem. If you have good tags and arn't speeding it is unlikely a cop will even pull you over. There are too many **** Cincinnati cops though if one pulls you over in that beast they'll probably give you a hard time about it.
