My car is 98% stock, but i want to put some headers on that will give me some tourqe and some throttle response, which are best ?

 

A lot of people seem to think that the SLPs are the best, and I have to agree with them even though I have no first hand experience with them. I can say that I have been VERY happy with my Edelbrock TES Headers that I bought from Summit for $320 or so. If you have the money ($500+) to buy a set of SLPs, then you might want to consider it, but there are lots of people who spend less and are very happy with them.

If you plan to stay close to stock then I would suggest the Edelbrocks, well unless you live in a place where they salt the roads alot in winter. The SLP's are stainless and will never rust. They also flow more if you plan to add more airflow later.

I have posted many topics like this one. I will tell you the results that I have had. Most people recommended the Eldebrock TES Hedders. They said they were the easiest to install. They also said that you should ceramic coat them, so that they will not erode and rust. Everyone who has spent less on the Eldebrock TES hedders seemed to be very happy. They have said that it is the best bang for your buck. Therefor I have decided to go with the Eldebrock TES hedders. I originally wanted the SLP hedders, but they are obviously expensive. If you have the money, then get the SLP's. But I have been recommended the Eldebrock TES's. I personally have no first hand experience with any of these hedders, but this is all the info that I have been told. Hope I helped.

 

For the cost of Edelbrock headers plus coating them, you can get SLP headers, which flow better, and have all 1 5/8" primaries instead of 1 1/2" primaries on the Edelbrock headers.

I've put hedman hedders on my 350 GTA. They're not too expensive and I've got good results with a dynomax race magnum muffler. The only deception I have is for my muffler: too quiet!!! The race magnum serie muffler have a straight through desing and give and excellent air flow but that does'nt sound enought loud for me! But if you look for the air flow that's the right choice.

 

Dude, I know, just like me you want to get responces to your Perticular post.Nothing wrong w/that.Also alot of people are ready to give you a lot of opinions(good,bad and ugly).Also nothing wrong w/that.You know that old saying: Opinions are like A-holes, everybody has one, and nobody wants to hear it,but you also can't live w/out at least one.
My point is, there are a lot of posts as far as the "header question". Scroll for them and look for them all. There's a lot of info in the old posts,and a lot of As...err, opinions on the subject.lol.
Really, read all of them and also the archives.
As far as my opinion. I love my TES. The difference from stock exhaust, is incredible!But w/a mod like headers you will benefit more w/a different Prom.There are even more opinions on that subject.
Just remember, ANY HEADERS ARE BETTER THAN YOUR STOCK MANIFOLDS!!!

ok here is the deal...SLP headers are NOT 500+ bucks. no way. i got mine for like 349 i think. i had edelbrocks and i was EXTREMELY disappointed in them. the exhaust "ports" were sooooo small i could not believe it. they advertise them at like 1 5/8", but in reality they are like 1 3/8" IF THAT. and...they look like complete CRAP unless you get them coated. so take that 350 bucks and add 150-250 for coating them. quickly adds up to like 500-600+ for the edelbrocks.

the SLP ones are more initially but they DONT have to be coated since they are stainless. and the quality is AWESOME. they look kick a$$ and have really good construction, etc.

i would get teh SLPs over edelbrock any day. thats just my 2 cents of course, but i have had them both and there is just a huge difference in the two.

On, one more thing. If you're on a budget, don't worry about rust or coating or all that mess. Uncoated headers will last you many, many, many years, unless if you live in a state where there's a lot of snow and rain.And if you happen to live in such a state, than your headers will only last for about 5 years or so.
There is always things like www.por15.com.

Looking For:

87 IROC-Z 350 TPI
84 TRANS AM 305 H.O.

 

SLP headers are/were $470(including the instal kit) shipped to your door from the GP. I'm not sure if that deal is still on.They are about $450, regularly.Add $80 for the kit and S+H.Now you're looking at $600+.SLP ARE MUCH HARDER TO INSTALL!!!
TES cost me $350 shipped, and they are a breeze to slap on.You don't have to coat them,eather.
Are your stock manifolds coated? No.They are not.Unless you want your headers to look pretty, there's no need to coat them.SLP rust too.Most people that have the money to get SLPs, get them coated too. Why don't you ask them, why?
I'm not promoting TES or ay other Brand Name.Choose as you will, but keep in mind: Do I wan't the most popular headers? Do I want pretty headers? Do I want headers that easy to install? Do I want headers that I can use in the future in case I modify my motor?Do I want headers that wont cost me a $1000(PARTS+LABOR)
Remember, even if you install the headers yourself, it's still doesnt mean FREE instalation. Unless you consider your time FREE.

Some of u guys must be right i must be a freakin idiot. I thought coating a header was mainly to trap heat inside the header, thus flowing potential increases. I know there for dependability as well, so the headers dont corrode.

Edelbrock TES headers are a great improvement over the stock manifolds. Although my friend has an 89 Iroc-Z and ran a 14.2@96mph with just all the free mods (except ram air) and full exhaust. He has the SLP headers and an aerochamber catback. On my 88 rs i had a full edelbrock exhaust and was VERY pleased. The sound at idle was low but when you got on her she barked loud. I think the TES headers flow very well and almost as well as the SLP but not quite as good.

Anything is better than stock manifolds.

They dont. See the reasons listed above about port size and primary tube size.

 

SLP, I wouldn't have it any other way.

Hello???? Hooker!!!!
They have been around the longest, and in my opinion have the best rep of all headers.

 

If it's not made of stainless steel, it is not worth getting. Anything else will rust within a year uncoated, and shortly thereafter if they are coated. Ceramic coated, jet hot. I've seen them rust. The guy I bought my blower from had Hooker long tubes sitting in his garage, jet hot coated. He never used them once, and they were brand new. They started to rust from the condensation! Just from sitting there. Unbelievable.

Headers are a major pita on our cars, if you get the slps you only have to do the job once. By the way, the SLPs outflow the Edelbrocks 7 days a week, twice on Sundays.

Get the SLP's if you have the money.

If you have dual cats then the SLP's will also be easier to install.. the Edelbrock TES dual cat setup doesn't include the pipes all the way to the cats, just two 90* turns where they come down out of the engine bay.
