I wanna get rid of all the smog control crap on my 5.7 tpi. All the little lines coming off the exhaust manifold and hoses related to them. I don't car if check engine light is on or not, just wanna make sure it dont kill the idle or power.

Rip it all out, who cares about our environment and our future? As long as you have no smog check where you live tear it out. But remember you are what you breathe or eat, I don't remember

I already feel my skin falling off, please keep your emissions and our future generation will thank you.

I figure all that crap is on there just so for looks. It probably dont do any thing but make the epa or some tree hugger organization happy.

And you can breathe easy on that, and so can everyone else?

the real emissions controller is the cat. converter.
all the air pump does is pre-inject air into the exhaust path, yes the EGR does some, but the big honcho is the 'verter...

as far as an SES no (well actually yes for the EGR), but it would also be better to get a chip with the smog delete info in it. From what I have read when the car activates the EGR/Air pump it alters the O2 sensor reading to compensate.

and yes I have seen cars with propper tuned chips that actually had lower smog without the EGR/AIR than similarly equiped cars with SMOG but a stock chip...
and yes both still had 'verters.

Thanks I wasnt sure. I just hate looking at and having to work around that clutter.

don't be a leg

well, if you want to help the enviroment and cut down on emissions, crush your old fbody, and go out and buy a new hybrid honda




btw, i'm just kidding.

Emissions equiptment has an effect on the ECM (or visa versa?).

Not much, but to do it correctly the prom needs to be modified. If you leave EGR you will notice nothing.

Has anyone ever read the tech articles about how they have taken Small Block chevs and made them burn just as clean w/out any emissions devices as ones that are controlled be all the emissions? Just curious cause I read a couple of articles claiming this. They claim you can make your engine just as efficient as a smog motor if you pick the right components and have it tuned properly. Im not saying to remove it or keep it Im just saying maybe it's possible that you can make it run just as clean or close to it.

Removing your emissions controls on a street vehicle is a FEDERAL offense, regardless of your state's local emissions requirements. If you're caught, you can be punished by a fine, jailtime or both. Please help stop the negative stereotype we hotrodders get. Properly maintained emissions equipment use up very little horsepower but do a great deal towards keeping our environment clean and our cars dont smell like raw fuel and rotting corpses.
We have cars in California passing our tough smog tests, running 12 second ET's, and making over 300 HP to the wheels. If we can do it, so can you.

What, do you think your car is going to be faster or something by getting rid of all that stuff? I think an engine compartment looks worse when all that stuff is missing.

maybe he just wants to get headers...!?! Anyways does anyone know where you can get a chip made? Can shops do it or does it have to be special ordered.

84L69TA

He can run headers with an L98 and keep all that stuff. Youre looking to have PROM work done for an L03? What mods do you have that will justify the money and time that would be spent on that?

All I have right now is a open element, edelbrock headers, custom y-pipe, hi-flow cat, and flowmaster cat back with 3" pipes. I was just wondering where to get a chip so i would know. I wouldn't get one until late next year anyway. I need to pass emmisions.

lol that was simple enough
oh yeah i have a 3.73 posi too

Performance Resource makes chips that work w/emissions stuff removed.

I removed all of it and have no check engine lights or any ill effects. It does look cleaner on the sides of the engine and less cluttered. Changing plugs is a whole lot easier to. Dont worry about the enviroment guys, I only drive it on the weekends!! LOL! Besides I am a railroader and have you ever seen what those diesel locomotives are putting in the air. My car aint the problem.

My car stunk like gas under the hood badly. all the emissions hoses was bad. The fumes were making me sick. So i riped it all out. pump,cat,AIR,egr. now it only stinks out the back of the car. and i breathe much better now. The moral of the story is the fumes are gonna get into the air anyway.

MrDude_1

yea, to answer your question a little late... yes, you can remove the smog pump without any SES lights... just run a shorter belt and follow the how-to in the tech artical on the main page.

might as well leave the EGR... its not in the way, and you need to tune for that one to get out...and it helps MPG... (btw people i know about the airpump thing...the effects of the O2 offset and the pump delete is minimal...)


btw this thread illustrates perfectly the problems with this site.. half of you are acting like treeswinging nut huggers, and the other half are acting like irresponsible idiots.. you're both so out of wack, its stupid.
just answer the damn question or shutup. thats how a tech site works.

Some people are ignorant of the laws, and I would hate for someone to tell them info and then have them get into trouble for it. For instance, some states have strict emissions laws, others do not. If one posts a question like this asking if one can remove the emissions equipment, someone from a non-emissions state will say to go ahead and remove it. So he does, but then goes to his next emissions test and gets in trouble for it, and the car will not pass the test. And since he was told he didnt need the smog stuff, he threw it away. Now, his car will not pass the test, he cant get his registration, and now has to spend more money to find discontinued parts to put back on his car because of some bad information he received on this board. Plus, our "hot rod" hobby already gets a bad name from the public thinking our cars are a bunch of gas guzzlers and pollution creators, I would hate for our members to keep that bad name going. Some real tree-hugger politician could get on this forum, see all the posts about people removing their emissions equipment, and decide to pass stricter emissions laws in his state where there were not laws before.
So, do you understand why I post what I do?

I have the same problem, Ive got a 5.7L TPI and im trying to replace a head gasket and all that crap is in my way, i was wondering if i can just take it out too without any problems arising from the check engine lights? I have never had a emmissions check and neither has anyone I know of had one, besides it sounds like all it does is pump air into the headers to cheat the system anyway? whats the point of it again? I have a good cat and thats all you really need, I was wanting to replace headers while im at it and I keep seeing something about an oxygen sensor fiting, do i need this with the headers if i remove this crap, or is it not related? I dont know much about the TPI

Thanks for your help

robmonte

cannon007 keep your o2 sensor. As for all this other stuff about emmissions just keep your car legal. My dad's 79 f-350 is exempt because it weighs over so many lbs, and so are cars that are so many years old, and I know in a certain state (maybe not all) that if the car is your second you can get something like historical or classic plates and be exempt. Keep it legal and we can't complain.
