Hi guys,
I am about to do a engine swap this winter see the thread in either engine swap or tpi boards. Here is the link to the engine....http://www.sdpc2000.com/catalog/1578...rip-Engine.htm

So with that set aside, I was looking into getting coated headers for her. So I am debating on the Hooker shortie 2055's 1 5/8'' primaries or the SLP 1 3/4'' headers. Would I lose any major power going hookers? Would I see ANY gain going with SLP's? Thanks for your input!!!

you'll gain a new vocabulary of bad words trying to get those SLP's to fit in, very tight fit with the brake lines in the way.

i really like the hookers they fit great the price is awesome you cant go wrong with the 1-5/8 tubes along with the 3''collector,get the non em.set and get the air tubes for an LT1 car then have them coated.
i like the slp 1-3/4s just as much the collector size is fine due to the primary tube size so you will be fine there,the slps are stainless but the problem is after long term use these headers will break at the air tube due to heat so get them coated problem gone,they can be a bear to install,i will tell you this if your car has not had new mounts get them before you instal a set of headers it makes the install soooo much easier(polymounts at that)all in all which ever set you choose you will be happy if you do these things to them!!!!

Bimma86

so if I go ahead and get new motor mounts the SLP's will fit after some, well issues.... I mean I wont have to dent one of them to get it to fit will I? I actually plan on removing the AIR stuff most likely, will that help at all?

If you do get the 2055s and don't want the AIR tubes, you'll have to remove/weld them up before coating. I think you can buy theym from ACS headers and they will do that for you.

92droptopws6

iTrader: (10)

you should have a regular install of these headers,i have installed both types of headers since late 1989 the older the car the harder it is to install due to wear,motor mounts and actual body shift,the slp1-3/4s you may need to loosen the 10mm bolts and the 13mm holding the steering column to the dash and firewall and move it to the driverside as far as possible to make the tubes clear.......

Engine swap on a 50,000 original mile IROC-Z? What about finding a good high mile car to do that to?!

1 5/8" should work with the way the TPI makes power better IMO, but the 1 3/4's would probably make more HP and less TQ. I'd ask the company as they should know about the engines they sell. They did dyno that engine with 1 7/8" headers though. Anything's better than manifold's though, even some 1 1/2" headers!

Wootah

My 2055's dropped in like a breeze... i was doing mine during my engine swap though so alot of stuff was ripped out of the bay, but since your doing the same thing you shouldnt have any problems.. all i did was cut off the AIR tubes, weld them shut, port the collectors, size up to match with the Y pipe.. bolt on fit perfectly.. and with the 2055's youll get the y-pipe...they work great with my engine setup and im pushing more power than you will be so, id assume the hookers are fine for your application.

OutLaw305

cant you order the 2055s w/o the air tubes?

25THRSS

nope

QuickStyle

do the hooker 2055'? have a c.a.r.b OE number? smog legal in california?

rsn932

ACS will cut off the AIR tubes for you if you want.

the 2055s with no modifications do have a carb eo number, but it is only valid if your car is an 86-92 (might have those years wrong) TPI

CA legal for '86-'90 single cat TPI only.

25THRSS

I wouldn't use ACS if they payed me to.

rsn932

lol not saying that i would either, i got mine from jet hot. i have no personal experience with them though so i really cant say anything bad about them. i heard they have been having some problems lately but i thought everything got cleared up. they are a board sponsor anyway so i thought i would throw the option out there.

five7kid

iTrader: (14)

A word to the wise: The "board sponsor" thing is an issue we're all concerned about. Check the thread they started way back when they became a sponsor to see the latest on what's happening.

As far as I've been able to tell, the problems have not been resolved.

At this point, I'd recommend buying the headers, doing whatever modifications to them you'd like (mine would be to open up the collector ball flange centered where the down-pipe mounts - this requires a trial mounting on the engine and in the chassis), then send them off to a coating outfit you are comfortable with. You'll probably pay more for shipping that way, but at least you'll have an idea where they are.

From what I've heard (understanding this is with absolutely no direct contact with SLP's except for an old pair of their tri-y's that hadn't even been installed), for the SDPC Vortec TPI crate engine I'd go with the 2055's, modified and coated to taste.

Bimma86

thanks five7kid, I am pretty sure I am going with the hooker 2055's. I dont want to hassle with the SLP's fitment issue which I might encounter. You guys are the best and have helped me sooo many times, thanks again!

I just got my 2055s and, as mentioned before, those ball flanges get REALLY small and need to be modified. I just measured mine with a caliper and it is 1.9" ID on the ball part of the joint (header collector). Work, work, work, everything needs to be modified to fit well. SLPs would be about perfect if the ypipe was 2.5".

five7kid

iTrader: (14)

1.9" is what I measured on mine, too. Holley/Hooker claims it doesn't affect performance - they may be right, it may even have an "anti-reversion" effect. Sure goes against convention, though.

Personally, I opened them up. When I dropped the y-pipe last week to replace the starter, I noted that there is still a bit of a carbon ring around the collector ball (less than 1/4" at the worst spot). If/when the headers ever come off (350 in my future?), I'll open them up to eliminate the portion carboned up, doing the same for the flange ports, then send them off for coating.

OutLaw305

Im looking to get the 2055's as well, but im not sure of what you guys are talking about in regards to moding the header. Which parts are you talking about? (sorry if im a little nieve when it comes to exhaust)

iceman02

iTrader: (1)

The problem is that the ball connector necks downs to 1.9" on each collector, as seen in the pic. They should be opened up (maybe five7kid can provide a good technique on how to do it) to reduce this restriction. Good point though, that you should put them on first and bolt the ypipe up to see what you should and shouldn't remove.

Avenger007

I almost ordered a set of slps due to the recent price drop but now im not sure. My setup is going to be 425-450hp and i dont want an exhaust restriction down the road. 2055s look great and id hate to buy the slps only to bang up my car to get em to fit.

Can we get some info on what to do for modifying the 2055s. I was thinking just cut off the ball at the collector. Is that the only problem area of them?

92droptopws6

iTrader: (10)

i would not use the 2055,the ball flange restriction is terrible i use the 2460 due to the 3"collector and have a custom y-pipe made.i used this set up since these headers came out in 1991,my last camaro tpi 5.7,hooker 2460 custom y-pipe no cats,t5,3.27 9bolt,cut air boxes,k&n filters,slp crank pulley,3" intermediate pipe,slp muffler,stock chip w/180 thermostat,alum driveshaft,17x9.5 eagle 203s 275/40/17 comp t/a"s(not drag radials)1.9 60' 13.7 @102 2400'altitude,my friend has the same set up but with the edelpoops and he cant even break the 13s

The slps dont require any banging of your car to install them, nor do they require any banging to the headers, some people just dont know how to make something work and go saying its a problem with the maker, these parts are made for cars from over 20 years ago, yes they may take a little extra effort to install properly, but it can be done.

iceman02

iTrader: (1)

Don't the new 2460s have ball flange collectors? I'm thinking of taking the 2055s back and getting the 2460s and the NEW matching ypipe and modifying it.

Avenger007

Iceman where did you find the new matching y-pipe? For those wondering about $$ differences and specs heres a few things to look at:

These are all ceramic coated prices:

Hooker 2055: 1 5/8 18g. Problems: collector gets small. Avg price: $550.00

Hooker 2460: More durable than a 2055 header (and heavier), but thicker 16g is more restrictive. Collector is larger than 2055, but by the time the exhaust gases reach the collector they have probably slowed down. No Y-pipe - budget about $150.00. Avg price: $330.00 (summit price, ive heard that ACS sells coated for $260 but i wouldnt trust them)

I was thinking of buying the 2460 and fabbing up a y-pipe that would go to a dual exhaust setup. It all depends on how well the y-pipe looks that comes with it.

Also, hooker has the 2460 under their competition line for mild setups while 2055 is under super competition. Ill have to call them to see how they differ in flow.

QuickStyle

where did you find the ceramic coated 2055's for $550? the cheapest i could find them was for $700

iceman02

Here's the thread on the new 2460 ypipe....
https://www.thirdgen.org/techbb2/sho...hreadid=267550

This place has coated 2055s for $519....if I'm not mistaken
http://www.fastpts.com/cgi-bin/hazel...m=hdr8292.html

Avenger, the 2460 ypipe looks identical to the 2055, except it joins up to 2.5" instead of 3". This wouldn't matter to us who will cut it off anyway to fab up a dual setup. I do like the way the SLPs turn back toward the cat before joining. It would save me buying a couple of mandrel bends.

I think the 2460s would outflow the 2055s because they have a true 3" collector, but if you can modify the 2055 collector ball flange to get close to 2.5", then it wouldn't matter anyway, since both ypipes are 2.5".

Avenger007

thanks. Those are good links. It looks like the 2460 y-pipe is pretty much junk. I could probably spend $175 and get a much better setup.

As for the dual setup i was waiting to see how well that y-pipe is to see if i go single or dual setup. Ill still be looking around but think this when comparing 2460 vs 2055. I am non-emissions vehicle (AIR delete) thus the 2055 AIR tubes are redundant and annoying. To have them removed its anywhere from $30-50 (from the seller). Then consider the price of them after coating. So lets even say you dont remove AIR and you compare price of the two.

2460 coated: $260 no y-pipe, allows $260 to spend on y-pipe or custom dual exhaust
2055 coated $520 w/ y-pipe, collectors would need modifying to be 3" and plus you still have AIR tubes to deal with.

2055 can be modified to flow more but 2460 are half the price.

Then consider SLP which are around $600+ after you buy install kit and what not.

It would be nice to see flow comparisons of 2055 vs 2460. This could consist of 2055 w/ its standard y-pipe and 2460 with a well-built 3" y-pipe to see how much the 16g is affecting it.

Orizon

ya i am buyinh coated 2055's within 2 weeks and cheapest i could find was like 700$ that link above, according to thie legend, the 2055's do not come with the y-pipe from them, which doesnt make sense to me but thats what it says. though id point that out, ill contact them b4hand cause thats a hella better price if y pipe is included as it should be.

If you move your steering column over and move some brake lines out of the way, the SLP 1 3/4" headers won't have any problems. You may have to shave a little bit of material off from the bracket that holds the column, but there aren't any major headaches, the brake lines move very easily

Tony

Avenger007

Orizon- $700 for coated 2055s is outragous. And if they quoted you that much without the y-pipe then forget it. THeyre out of their mind. Hooker 2055s only come with the y-pipe its a package deal no matter what. I had one local place quote me $560 for coated headers AND y-pipe. Look for them to be around $515-550 in price.

I think im going to follow greeze monkey's dual setup but instead go for 2460s. I figure they cost $270 coated to my door. Then $130 on cats. $200 in mufflers. Then another $200 in tubing, maybe less. To me, a dual 3" system for $800 would be worth it to get the 2460s.

To compare the above setup to a single system, lets say you take 2055s since they have a nice y-pipe. $550 for them plus $60 for a cat. Now you need a decent cat-back which is around $250-300. Now your talking $850-900.

I guess it all depends on how much time you want to put into it.

Ahh....i can already hear the pure sound of duals screaming down the street...

Orizon

jethot wants 720 after shipping for 2055's coated. summit and jegs are both right around 700 also and the local place i can get them from, tognatis wants 750. so the only place ive seen em for less is in the above post for 519 but according to it, it doesnt include y-pipe. gotta call em to find out. ill call tomm.

just called em but he had been closed for 10min and said hooker is closed and he would call them tomm. to find out and call me back. but if thats the case then it seems it will come with it if they are getting right from hooker so 519 for a set of coated hookers hella beats 700 that i was about to spend. thanks for saveing me a 150 bucks :hail: :lala:

Where did you see that it said no ypipe? Here's the way I decode the symbols. @ = Fits TPI engines w/single 3" Cat. Con. Includes Y pipe Maybe I missed it?

Orizon

they called me back today and yes it includes the why but their website is outdated and its 680 for the coated 2055's plus shipping, so theres that 700$ mark again. if anybody knows of a better price lemme know

iceman02

iTrader: (1)

Ha, thats funny. I talked to them the other day and they didn't mention a 'price hike'. Guess they forgot.

OutLaw305

I talked to a tech guy from jet hot earlier in the week. He quoted me $650 for the headers and y-pipe ,discounted for thirdgen.org, shipped to my door. For 40 bucks they can send them to a machine shop there to open the flanges and cut/weld the AIR tubes.

IROCZTWENTYGR8

They are a very good company. I hope to have them sponsor here some day if we can ever get it going again.

Avenger007

Thats crazy! Did the price of 2055s go up? I know that ACS has been selling em for around $550 coated. Just read the ACS threads and youll see people who got quotes from both jet hot and ACS around $550. Thats what they both quoted me when i asked about a month and half ago. If $700 is what they go for nowadays then i sure as hell glad im going to 2460s. I could buy a new cam for what that price diff is.

Though hearing all the issues with the fit of the SLP headers...I decided because I'm having my mechanic install them to buy the SLP 1 5/8 coated headers with air for my 305. After seeing the current prices for the hookers and considering the sale that slponline.com is running on the headers it was a wash and the fact that they were stainless steel sold me on them. I also bought a dynomax catalytic converter from jegs. This will all lead to my 80 series flowmaster muffler. Hopefully everything will be here towards the middle of next week.

QuickStyle

i believe that the slp coated headers are aluminum and the non coated headers are stainless steel.

Avenger007

ya i believe thats how they have it setup. I dont think they would coat stainless steel. Plus FYI stainless steel expands greatly when under a lot of heat. They are good in some aspects but not in others. I would just look for a good coated set.

Plus SLPs do require an install kit so even though they are running the sale on the website they still cost a lot.

Where did you hear that from?

it says it right on slp's website

It says they're constructed of 409 SS just like the uncoated....

SLP Polished Aluminum-Ceramic Coated Headers

copy and paste from there website

Jose'sRedTA

Its kind of confusing on the site but I'm pretty sure the polished aluminum-ceramic refers to the type of coating...

From the site:

Polished aluminum-ceramic thermal barrier coating keeps heat in, exhaust velocity up, and underhood temperature down

a few lines down:

Are crafted from mandrel bent .055" wall thickness 409 stainless steel tubing for smooth uninterrupted exhaust flow

Have 3/8" thick, investment cast 304 stainless steel flanges for better sealing and long life

I'm supposed to have them at my front door by the end of this week...lets hope that is true...ideally I'd like to have them installed right after christmas. I got my dynomax catalytic converter yesterday from jegs...It came two days sooner then expected.
