On my friends GTA I took the emissions crap off for him but I need something to cap the tubes coming from the exhaust manifolds. I seen some1 use some caps b4 where can you get them and what size does anyone know??

r0nin89

If I remember correctly its a 1/4in plug. Look at the tech article on removing it.

Spdfrk1990

Which 1 I couldnt find it?

just take the tubes to the local plumdingsupply/homedepot/lowes and matchup the threads with pipe plugs

*cough* *hack* *wheeze* I cant breathe, what's going on? Oh, its just your friend's car in front of me spewing extra smog into the air because you were so kind to remove the "crap" off of it.
I hope he doesnt get caught with a fine and/or jailtime for violating a federal law.

boosting28psi

^^^^ are u a freakign idiot????? they're no more Echecks......so why do you need smog parts on your car???? you just made my iq drop dude......go back in your hole....how did you get to be a mod. anyways?

Spdfrk1990

I found some caps we had that were on some lt1 headers. If you think that air pump makes that big of a difference in pollution then you can keep yours on. Also we are trying to setup this car so he can take it to the track it is not driven on the street much.

Removing the Air Tubes and Smog/Air pump wil not make your car smell any different or fail emissions.

Removing or gutting you cats will.

Want to drive behind me?

Spdfrk1990

If it makes him feel any better it has no cats also and we deleted the egr haha.

jak2908

how much improvement did you find on removing that smog crap? been thinkin about it myself..

Air_Adam

Hey hey... be nice - Kevin91 is right.

It is federal law that those parts are supposed to stay on the car and be kept in good running condition. Removing them, whether you get caught or not, is still illegal, and there are fines you could be slapped with if caught.

There really are no gains to be had from removing most of your emitions components. There are only a few that will detract from potential power, and the ones you removed aren't among them. All that will happen from you removing the AIR system components is that the cat converter will clog up sooner, which WILL hurt performance.

Now, to answer your question -

If you do want to buy the caps to plug the manifolds anyway, you want to find some 1/4" NPT pipe plugs. You can find them at almost any hardware store (Home Depot, etc) and many automotive stores, like Auto Zone maybe, that sell plugs and fittings and stuff. They will all have that.

As Air_Adam said, it doesnt matter what your state's emissions checks are, removing your emissions equipment on a street driven car is a FEDERAL offense. Now, whether police in your state choose to enforce it is another matter. By removing smog parts from a street driven vehicle, you have proven to politicians that the current smog laws are not enough, and they'll need to make more laws to combat people like you who ignore them.
I became a mod because I am knowledgeable in many areas of exhaust and smog equipment. I'm also familiar with emissions laws and requirements in many parts of the United States, unlike you.


He didnt say he just removed his air tubes, he said he removed the "emissions crap" which to me is more than just the air tubes. My guess was confirmed in a later post where he said he removed the cats and EGR too.

Air_Adam:

Finally: If I can make 300+ horsepower to the wheels and run 12 second ET's and pass CA smog with everything hooked up and working, so can you. Stop giving our cars and other hot rodders more of a red-neck image.

Removing emissions = uncluttered engine bay.

iTrader: (12)

Does your engine call you up while your driving telling you it's too cluttered?

-- Joe

Spdfrk1990

It tells you when you open the hood and you cant see the pass side valve cover.

anesthes

iTrader: (12)

I can see both my valvecovers.

to quote my old football coach - "Anything is legal unless you get caught."

Spdfrk1990

Are you still running the air pump and the heater lines over the valve cover??

Spdfrk1990

Heres a b4 and after.

anesthes

iTrader: (12)

Looks like the heater, and A/C is whats causing your valve cover to be hidden.

-- Joe

Spdfrk1990

Look now the after wasnt showing. It was the air and heater lines a/c wasnt blocking any of the valve cover.

anesthes

iTrader: (12)

So you unbolted the diverter box thats held in by two bolts?

I never had a problem running one. But to each their own.

-- Joe

Spdfrk1990

Are you kidding I unbolted that and removed all the air lines, moved the heater diverter and did a tb bypass, removed the carcoal canister and its line to the tb, and replaced the breather line with a filter instead.

anesthes

iTrader: (12)

Why would you remove your charcoal canister?

Spdfrk1990

Like said b4 its unessesary clutter and this is my friends car I just worked on it. You can just remove the canister and put a filter on the end of the line. The canister really isnt going to save much gas.

Egg83

Spdfrk1990, but who/what makes you qualified to deem emissions control equipment unnecessary? Judging by your statments throughout this post you don't know the operating fundamentals of these systems. A charcoal canister on a vehicle is not there to "save gas", it is there to prohibit hydrocarbon vapors from venting into the atmosphere. I am sure that your buddies car has really nice valve covers that he's proud of, and wants everybody to see. For you to remove the items you mentioned that "clutter" the engine bay is rediculous.
Do you think that disabling these devices will make more power? It is a proven fact that modern emissions control devices do not hinder performance unless they are faulty. The only thing which may remotely draw from engine power is an AIR pump. The power required to turn it is so insignificant that it doesnt matter.
Before you disable devices, of which you have NO idea of their function pick up a book or some literature about what they do before arguing with the mods about how much of the valve cover can be seen. Afterall, who cares about violating federal laws when you have painted valve covers anyway. -Bob

Spdfrk1990

Oh my I know what the hell a charcoal canister does I really do not care about emissions I would care more about saving gas. You are wasting your breath you are retarded if you think they are needed. The egr I dont like to have either cause I dont like the carbon buildup it causes.The air pump is not needed hardly any cars even have it any more all you need is the cat. Wow you are talking about violating laws now you should come to the drag strip I guess all those guys could be fined you got to be kidding me. I have read many books and worked on many engines but no I dont know what anything does. So you guys like actually want to keep your emissions just need to shut up cause thats your decision and not what we needed on this car since its promary function is to race. By the way tonight it ran a 12.72 and that is 100% bone stock with a 150 shot.

Air_Adam

You've got to start showing these guys some respect, or no one is going to want to help you anymore. Just a little heads up.

And if you are keeping the cat, you DO need the AIR system. It helps the cat get as hot as possible as fast as possible, SO IT DOESN'T GET CLOGGED!! Just like I said in my first post, if you even read it.

As far as laws go, nothing applies at the drag strip (duh)... thats what "off road use only" means on aftermarket parts that are not street legal and/or emissions certified. No laws apply anymore when its at the drag strip because the car is off public roads. Thats why they all run with no emissions equipment, no mufflers, race gas, non-DOT racing tires, etc etc.

Spdfrk1990

Ok for the 900th time i know what it does I dont need an explaination I was just asking about where people got there freakin caps my god. I dont need any help from retards on here I was just helping a friend out. Thats why I havnt talked on this board pretty much for over a yr. I talk on many other boards and none of them have the stupid comments like this board.

anesthes

iTrader: (12)

Give up. I did. He's right about the retards on the board too, he just doesn't realize which side he's on.

I've been on here a long time, and realized you just can't help some people. Let him enjoy his clutter free tuned port turd, I'll continue to drive my 500hp car that passess emissions like most honda's and doesn't make the guy behind me pass out.

Peace.

Egg83

I concur. -Bob

Spdfrk1990

Did I not say this car was being ran at the track? Did I not say we dont even have emissions here? Im done cause you will just keep coming back with ur opinion thats all it is doesnt make me or you right. Oh this car doesnt smell bad or make you pass out lmao. Why dont you go start your car in the garage and stick your nose in front the exhaust for awhile.

rwdtech

WRONG! the AIR tube is there to put more oxygen into the catalytic converter so it can convert the oxides of nitrogen, carbon monoxide, and hydrocarbons into CO2 and H2O more effectively. It is an old design. Modern 3 way catalytic converters dont need AIR. You can buy a modern catalytic converter to solve this. I dont run AIR with my headers beacuse i bought a new high flow 3 way cat.

anesthes

iTrader: (12)

The #2 feed is for that, but the manifold lines is just for warm up to get the kitty as hot as possible. The air goes to the manifolds for only a very short period of time, then it switches to just te cat.

wow this sure is a hot topic. i ran emissions equiptment since i got my car in 2002. it always stunk like gas and even under the hood/passenger compartment. i could never drive with my windows up. finally tracked the problem to the cat being bad and a heater hose that was used to pipe exhaust gases from the drivers side of the engine to the passenger side where that valve thing is. living in a non emissions state i decided not to deal with repairing it. if you don't have to fix it then don't. i pluged the holes from the manifold and pulled off the cat. it's not like it worked, i could see right through it. there was no white brick thing inside like i have seen on ther cat's. my emissions equiptment wasn't doing it's job. i was being sickend by fumes. the whole point of the system is to get rid of noxious exhaust fumes. if your emissions "crap" works then leave it be it's not the power robber people make it out to be. but if it's not working and your state doesnt require testing then no one has to know but you. the only time i ever had a cop look under my hood was at a milatary base. so when your ripping out all your "crap" i wouldent worry about a fine unless your state/county tests emissions. and it's not like me without a cat is going to "kill the environment and all that" there is no diference because my cat was burnt out anyway. by now the eariler third gen's are 20 years old. do you really think that the emissions equiptment actually works after all those years? take a look at your cat. most likely not in good shape. you could be polluting without even knowing it.

rwdtech

yes you are right

1/4" NPT plugs. This is right, right? Someone before me took off all the AIR stuff and crimped the pipes... so I might as well plug em.

hey guys.. you sound like children... common were all friends here.. we all love 3rd gen cars here.. you should not care what the other person does becuase you will never see him or her... now in canada.. we dont got to worry about cats or anything no test or anything.. but anywho if i get a set of hookers.. the 2460s.. do i need to block off those holes or are they only in the manifold?

Kevin91Z

iTrader: (1)

Wow, you brought up a month old thread just to add those two words? How immature.

sprslo92

bla bla bla all im seeing on here is a bunch of crap i took every thing but the cat off and my readings got better. explain that. trust me dallas's emmisions are almont to the point of california, iwould know b/c i inspect cars. newaz all im trying to say is whos gonna call the epa and tell them i took off the smog pump? all he wanted to know was what he needed to plug the manifolds with and a bunch of people started being retarded. just help him out and get off ur high horses.

anesthes

iTrader: (12)

Me thinks you should call GM, tell them that for 25 years they goofed, and that all that "crap" made the readings worse.

GM's gonna feel pretty foolish, spending all that money on R&D, hiring high priced highly educated engineers, when all this time some guy working at a gas station doing inspections knew better!

-- Joe

rwdtech

yeah GM engineers are REAL smart!

Fastbird

iTrader: (5)

yeah real smart! It took them until 2002 to take the EGR valve off the camaro because they realized...hey we don't need this!

As for the pollution and tree hugger attitude......

I drive my car with no cats, no A.I.R. right to the NJ inspection station and pass thier visual inspection because my car is exempt. I run Hooker super comps into a 4" exhaust on the street, and it is LEGAL. Point is, not everyone has the same rules applied to them or the same situation as you.

As for all the coughing, I think 116 leaded fuel smells pretty good out of the tailpipe. Maybe GM should make a perfume out of it. Now THAT is smart use of their engineering staff!

I bought all the 1/4 inch plugs but I read that loctite or JB weld should be used, does it need this? All the loctite bottles I read said not to be used near hot areas, or should i go with JB weld. thanks

got it, thanks alot. By any chance do you remember what you did with the pipe coming from the cat? plugged it or cut it off and plugged the cat?

cut it by the cat and take some vise grips and clamp it closed the roll it up and it should be fine
