Ok guys i am going to get the a/c delete pulley and then i want to get rid of the smog pump but what do i replace it with? I really want to do this please help!
thanks
kevin

 

will i also have to get rid of my manifolds? If so can i put headers on my car using the same exsaust system?

 

You don't have to replace it with anything. Take out the AIR tubes. You'll have to cut the air tube at the cat and cap it off. You can keep the manifolds and cap the holes with bolts.

Thats great i dont have a cat so that shouldnt be a big deal. Then do you know if i could put headers on my car with out changing my exsaust?
thanks

 

headers are a part of your exhaust. But if you are talking about your catback, no you dont HAVE to but to get the full effect of the headers, YES.

 

I did just the headers and it really didn't make a difference in power. I'm going to do the whole exhaust eventually.

 

I mean then whats the difference? I will be putting a new engine in oct and the headers will fit the other engine to so should i or not. Will it give me 7-10 hp?
thanks

 

If you want, they do make a smog pump deleter pulley. However, it's true, you do not have to replace it with anything. Throw that piece of crap in the dumpster and you can do away with the belts too.

If you put headers on your car and want the full effect of it you need to spend a little more money. You don't necessarily have to go full blown dual exhaust but you do at least have to get at least a 2 1/2" mandrel bent y-pipe and keep the intermediate pipe all the way to the muffler at 2 1/2". With a 305, I have never noticed any difference from 2 1/2" to 3" on the pipes. I'm thinking the real benefit is on a 350 but since we are working on a 305, that is that. Not to mention 2 1/2" is cheaper. I would recommend using a high-flow cat. I have a magnaflow on mine, works fine and no loss of power.

I know lots of people hate them but if you can do your small part to keep 'er clean, you should. Ok, enough with the self righteousness. If you haven't already put headers in, make sure (If you went cheap on the headers) that you use the thermal wraps on the headers. It keeps the underhood temp lower and that helps keeping that hot air from getting into your intake cause colder air is your friend, not hot air.

If you are switching out the engine, don't waste your time, just be patient. Bigj350 is right. You can toss the smog pump, cut all the air tubes and plug the manifolds.

 

At least do shorty headers now with a matching y-pipe, you'll see a little bit of increase. Thats what I got on my TBI right now. I also got a open element and took out the TBI spacer. I'm not sure, but I think it will keep up with my Grand Prix GT as long as my wife is driving the Grand Prix

 

ok i will wait but i want to know will getting the a/c off and the smog pump off will that give me 10hp? I want to do it anyways b/c all that stuff looks like crap!

 

I don't know the actual gains, but I have heard its around 10hp. Get an open element and get rid of that spacer.

 

Get rid of what spacer?

 

i think hes talking about the gold spacer at the top of the tb

 

The spacer that sits on top of the TBI unit. And then the air cleaner sits on top that. GM used the spacer to raise the drop style air cleaner so it wouldn't rub on the dist. and plug wires. I can take pic of mine and show you what I am talking about.

 

Well i did that when i put that air cleaner on. Do you guys think that is a good one or should i get something else? A freind gave it to me so i put it on.

 

im sure its better than stock not to sure how it compares to other ones out there but im sure its fine

 

Well by the stuff you wrote you have the same engine and rear end i got have you done anything to your car?

 

Not yet. I'm going to get the full exhaust done soon. I got some 601 heads I might do something with and maybe a cam.

 

right now my car just has a flowmaster catback exhaust but thats just for now i need to get a job so a can afford enything

 

looks like a cool ride though. I got a job about a month ago washing and detailing cars at this local car wash.

 

thats allways good u need a job to pay for car parts there arnt to meany jobs around my house for teenagers so im suck doin little odd jobs for not that much money plus not to much time with school and football training camp starting but maybe in the summer ill be able to find a job and get something good for my car

 

Its been posted many times in the Exhaust forum that header wrap is crap. It traps heat and moisture that will rot out your headers from the inside. Spend the money to get the headers ceramic coated or dont bother.

Why do you want to remove the air pump anyway? It provides a valuable service to remove carbon monoxide from your exhaust and doesnt cost any power to make it work, 1 or 2 at the most. There are literally hundreds of threads on this topic and its been beat to death. Its a very popular thing to remove as people are confused about its function.

 

No doubt Ceramic coating is the best and best looking. However, if what you say is true, why is it that every single tech article from every pro you see shows to wrap the headers with thermal wraps (the ones that aren't ceramic coated)? I have yet in many years seen a single header fall apart because thermal wraps were on them. Whatever, to each his own.

Sorry, we have to agree to disagree. The smog pump is useless. You can achieve saving the environment by slapping a high-flow cat' on your car just as good. When these smog pumps clog up, and they do clog up over time, they have to be replaced and they are not worth replacing for the price. Not to mention that headers that are made to work with the smog pump are ridiculously expensive compared to regular headers. GoodlookinRS is on a budget and I don't think he wants to shell out a couple hundred bucks more for smog pump friendly headers.

 

Please point me out some unbiased tech articles saying its a good thing to wrap your headers. The only ones I have seen are from the header wrap companies themselves, or magazines who were paid to promote the header wrap. It may be an old wive's tale, but it is a fact that coated headers will last longer and perform better than wrapped headers.

The air pump helps the cat do its job, without it the cat is less effective. Our cars came with air pumps and its a federal crime to remove it. If your state doesnt check, well then you're getting away with it.
If you cant afford to mod your car the right way the first time, can you afford to fix it again later? Someone with no money should not be modifying their car.

 

So i mean do you guys think i should put headers on? I will if you guys think it will make my car sound better and give what 5-10hp. I just put a flowmaster on and left the stock manifolds on i will as long as i dont have to replace my exsaust. Then if i can i want chrome ones that dont look like crap in 1hr. I want them always to be chrome.

So how much for the headers?
How much to get installed with my exsaust set up now?
thanks
kevin

 

I think we agreed that coated headers are better but just like most hotheads on this site, I'm going to respond with a hothead answer: goto Barnes and Noble or Books-a-million and pick up a book! You also forgot to mention they look better too.

A federal crime to remove a smog pump?! WOW! This is complete news to me considering I haven't seen a car with a smog pump since this era of automobiles. Removing a cat' yes, removing a smog pump? WOW! Never heard a shop tell me that either. Anyway, look here GoodlookinRS, if you are going chrome all the way, be ready to spend some $$$. Just to give yourself an idea goto http://www.summitracing.com and price and compare some stuff.
You already have the Flowmaster so all you need is everything else.
If you are totally in love with that pitifull piece of s#!t smog pump then be ready to pay the premium for headers that will work with it.

Just remember going chrome is going to cost you alot!!!! But damn, they sure look nice. However they are a pain in the a$s if you want to polish them. As far as paying someone else to install them, you are going to have to pick up a phonebook and call around. Putting headers on these cars with the engine in is a royal pain. Be prepared again to $$$.

 

What do you think about this kit.

Those headers are the coated version of the headers I used to run. I had to dimple one of the tubes to give the plug some room and the optional Y pipe is not the greatest. Overall they work beter than the stock stuff but are not the best. I would buy the standard version for a lot less money because you will want better headers later on.
Removing the AIR system makes no real power difference and neither does the A/C. I would rather add power with cams and save weight with fiberglass hoods but everyone is different.
Removing any emission equipment is illegal but that does not stop anyone.

 

I'm not going to do any major work to my 305 b/c with in the next year i will be putting a 350. I want to buy headers that will also work good with that motor to. The motor that i will be putting in will be pretty powerful making mid 400 to the rear.

So will these headers be good?

They are a much better choice for power. Hopefully they have a good fit.

 

So these would work good on my engine now and later on the other engine?
Everybody agree?
thanks

The AIR pump and its lines are considered part of the emissions devices the car came with, and as such its a federal crime to remove it or any other emissions devices. Its not enforced as well in states that dont currently have emissions testing, but believe me, its coming. You can thank your local tree-hugger, Al Gore, and every other person who believes in global warming.
----------
Neither one of those headers comes with a y-pipe, and neither will bolt to your stock y-pipe. Nobody makes headers I know of that will bolt to the stock y-pipe, either. So you can either have your muffler shop make you a custom mandrel-bent y-pipe, or you can get the Hooker 2055 headers that come with a y-pipe and are considered some of the best 1 5/8" thirdgen headers around.

 

Hold on man the headers i will be putting on is my flowmaster. i all ready have a flowmaster i just got the stock mainifolds.

 

Uhm, what? You are putting on flowmaster headers? I dont think they make headers, just exhaust. If you want to replace the stock exhaust manifolds with headers you will be very much ahead if you spend the extra money to get headers that come with a y-pipe, as I said.

 

While Kevin and I definitely have different opinions on the value of a smog pump , his advice on what to do with your exhaust system is dead on. If you were referring to Flowtech headers, you might as well just leave your stock manifolds on there. Flowtechs use puny 1.5" primary tubes and an equally puny 2.5" collector. They're cheap to buy for a reason. The same goes for the Hedmans and Hooker's 2460 headers. These are "affordable" since they don't come with a y-pipe. By the time you get a y-pipe fabbed up, you end up spending the same amount of money, if not more, than just getting the Hooker 2055's that come with an awesome y-pipe. I also have to agree with header wrap being a bad idea. Not only is it ugly to look at, it traps moisture between the wrap and the header tube, which causes your headers to rust out incredibly fast. As far as proof, I've seen pics of headers when the wrap is removed. The tubes either have pinholes all over them, or in extreme cases, they literally fall apart as the wrap is removed. Granted, ceramic coating is expensive, but if you can't afford it, you're better off just running bare, uncoated headers versus using any kind of wrap. Upgrading the exhaust system properly on these cars isn't cheap by any means, but using cheap parts makes the whole effort a waste of time. I'd say the Hooker 2055 system is the best choice, and the Edelbrock TES systems would be the cheapest ones that would still work fairly decent. You'll also want a good 3" aftermarket catback system to round the whole system out nicely.

 

Ok guys i have all the a/c and everything is out.
I have a flowmaster exsaust right now.
I just want to know what kind of headers to put on!
thanks
kevin

 

You have a flowmaster exhaust as in a cat-back or just the muffler? And they're telling you what to get as far as headers. Read their responses. Hooker 2055's are your best choice.

 

Their is no cat on my exsaust all it is 2 1/4 in pipe with the stock manifolds. I just wanted to know like the top three headers that are good.
kevin

 

There doesn't have to be a cat to have a cat-back. A cat-back is just from where the cat would be to the end of the tail pipes.

 

Ok i found the stuff everything looks good but you see them tubes i dont have that any more. I need something else.

Get those then. It's about 250 for headers and y..not the greatest y, but it's not terrible.

 

Hey thanks alot man you told me what i needed and where to get it now i know what to get and it will do the job! Will i also need to buy some gaskets?
thanks
kevin

 

Gaskets will come with the headers, but I would personally go get the copper ones instead of using the paper ones supplied. The y-pipe doesn't need gaskets.

 

That cool man thanks
kevin

 

Hey man i was woundering my dad put some really nice headers on the mustang and after like 2 hours they turned white and ugly will these do that to?
thanks
kevin

 

Without any kind of coating on them, they'll be rusty in a month. The black paint that comes on them usually burns off within a few days. Ceramic coating is expensive, but if you want them to stay nice looking for any amount of time, it's the only way to go. You might want to go to Jet Hot Coating's website and get in touch with them. They have the 2055's available with the ceramic coating, and it's far better quality than the coating that Hooker or Edelbrock offers from the factory. They'll also remove the air tubes and weld the holes shut before coating them if you request it. Here's a couple of pics of my 2055's from Jet Hot. I've tried just about every paint known to man on headers in the past, and none of them stay on for long. Getting them coated is the ony way to keep them looking good for a long time.

 

If i can ask you how much did that cost? I just want the headers chrome like that i wouldent really care about the y b/c you wouldnt ever see it.
thanks
kevin

 

They can't enforce it. They have no way to prove it's the stock engine. If you do an LSX swap then what, they don't have smog pumps. Cars this age, they can't prove anything. It could be a rebuilt engine for all they know. Most places are only looking for the cat'. I'm glad I live in Florida where we don't have emissions testing anymore.

That, I totally agree with!!!!

 

It doesnt matter if its the stock engine or not. If you claim its the stock engine then you must have all the stock smog equipment for your year of vehicle/engine. That's how they enforce it. If you swap in an LSX engine then you must have all the smog stuff for an LSX engine of that year. You're right, they dont have smog pumps so you dont need one for an LSx swap.

I heard Florida is doing smog checks now or soon in the future, you better check it out.

 

GoodlookingRS:

If you really want headers, just buy what you can afford.

In other words, just save up and wait until October to get the headers when you've got the other engine ready. A lot easier, plus victory will sound that much sweeter when you start it up the first time.
