Hey guys! Yeah I know, Ive been gone awhile cause I had family problems, got separated and had to cut DSL off to save a little money. Sorry to JET the way I did but I had no choice.

Anyways, I got me a set of brand new SLP Tri-Y headers for my Z...whats your take on them? Im going to get them coated........I did a search on them and didnt come up with alot...nobody must have them, huh?

What kind of gaskets should I get for them? SLP or something different? also, what kind of header bolts?


See? All I needed was the headers and I can start to put my top end back together....I just hope I remember how everything went, its beena bout 4 months since I even touched the car....been sitting there witht he whole top half taken off!

thanks guys!

 

WOW! they must be as rare as what ive heard, nobody seems to have them.....how bout any of my other questions?



thanks peeps!

 

i was gonna reply but I changed my mind

Daz

 

Glad you're back...sorry 'bout the problems, but it'll all work out.

Don't know much about the tri-Y. I've seen a pic...does that help?

Probably not.

 

Hey!...SEE i told ya that **it was gonna happen........anyways good to hear from ya....my car will be back on the road soon I hope@!?

one of my credits cards up'ed my credit 2000 grand so I gonna spend it on my car to get it back together, it should only take about 1000 at the most....yeah i hope?!!!

 

heres a pic of them...I got them from someone on Ebay selling them...cost a pretty penny but I dont care?...yeah righT!!!!!!!!!!its only plastic money....



LOL.....

Im gonna cut the air tubes off.

 

I had a set of tri-y's on may 350/84 camaro, up until recently. They are a great headers. Mine were not coated either. I upgraded to the slp 1-3/4 headers and so far I wish I still had the tri-y's. IMHO the Y-Pipe is a better design and fits and flows better than the new ones. Regular header gaskets will work fine . The gaskets for the y-pipe connection you may have to purchase thru slp or make them yourself. Short of long tubes,
the SLP tri-y"s maybe the best headers out there for the 3rd gen.

 

did you notice a big difference with the Tri-y's? The way they look they seem to be some what of a long tube design...huh?

 

The major difference that i noticed was in Y-pipe size(ie. two good sized secondary tubes vs one small "less" than 2-1/4 od secondary tube , fitment and torque thru out the power band in the combination that I ran at the time. Keep them until you are ready for LT Hookers. I purchased a set of the new SLP's because ground clearance is a concern for me.

 

If you can find a set, get them. SLP does not make them anymore.

 

anyone else know anything about these headers?

What kind of gaskets should i get? also what about header bolts? anyone know of a good site to go to for both?

 

a good friend of mine, firbird, as hes known on here has the slp tri ys and i coated them. i think they are a very nice set of headers except, from what i hear from him is they are prone to cracking in the seams. i hope they work great for ya!
p.s., from what i understand, he has to make his own gaskets for the pipes where they join from 2 to 1

 

nothing special you have the headers that slp back in the day put on the thirdgens that got the 'SLP Package"

they were 1 3/4 or 1 5/8 i think, i like the design alot better than there current 1 3/4's because they dont use those stupid crush gaskets things at the collectors. i still would call them shorty headers, and they have alot more clearance on both sides around the steering shaft and other stuff. seem to be a better tight fit.

 

guy must have bought some NOS of the Tri-Y's cause he has another set up for auction on Ebay. Thats the 3rd set I have seen him sell in the last month.

Check the auction out if you guys want-em.

 

yeah i saw the auctions, i think he is listing them to be 1 5/8 ones.

must of bought some them back in the day or maybe had some ties with slp or something.

 

LOL, new sig material.

I have the Accel/LPE tri-y's and I love them. They are pretty similar to the SLP's.

 

I put a set of the 1 5/8" SLP Tri-Y headers on my 1989 Trans Am in about 1991. It was the biggest seat of the pants improvement that I did. They are still on and look great. No problems except to tighten up the header bolts every couple of years. They are made of stainless steel and still look good. Allen

 

I bought a used set for $75 in 1998, they were mild steel - might not have been SLP's. They worked great, my 350 picked up a ton of low end and mid range power vs. the stock manifolds & Y. Ground clearance was another issue however... I used to have Eiabach springs up front and it dragged the Y on the ground every time I hit a bump in the road or went over RR tracks at speed. I took them off for some Hooker ceramic coated shorties and lost power. I felt it SOTP & saw it in my timeslips. Even though I have LT's now, I wish that I had hung on to those headers because I have never seen another set in person since. After using them for a year, I cleaned them up and sprayed them w/ a rattle can of silver heat paint, then sold them for $200 at a swap meet.

 

Just ordered a set of the Tri-Y's for my 90 IROC 350 TPI. I like to keep everything near stock/factory appearance and since these were actually sold in GMPP catalog back in the day, and they are a perfect match for the short of breath TPI long runner intake. Getting them coated by ACS. Gonna put ina set of 1.6 RR's at the same time. Can't wait for the snow to melt.

 

What do you mean they still look good? you never got them coated and they didnt turn all brown lookiing?


Feldme, where did you order your from, how much did you pay?

 

horsepower1 on eBay. Apparently he bought a TON of overstocks (everything he has listed) from SLP, or works for them, although denied it. I think his supply of Tri-Y's is dwindling as he had to make sure he would be able to ship my set and still keep another auction going on eBay. I emailed someone else who had bought them from him about a month ago from the feedback log and they said they were legit, new and in great shape so I took the plunge. Seeing that I keep my car in near stock form (only 31,000 miles) and these were an actual GMPP part at one point (for $995 I might add) I got them for around $500. Gonna send them and have them coated by ACS and install in the spring. If anyone else is interested checkout eBay fast.

 

yep!, thats who I got mine from. He is legit, I just wonder what he paid for the headers, I really dont care since Ive gotten mine already and I paid for them with my credit card so i'll be paying for years to come...LOL......anyways...He sells them outright for $500, they are going like wildfire, He has an auction up right now for a set.

Im going to send them and have them coated too, Im also going to cut the air tubes off since I've already removed all the air stuff from the car. I dont care if I could have gotten a set of hookers for the about the same price, I was going with SLP's anyways, and to be able to get a set of the TRI-Y's was great!

 

Hi Wishmaster's87IROC

No I never got them coated. They have turned a nice light grey color. They are not brown and scaley like some headers I have seen. They have been on my car some 13 years now. Maybe living here in Southern California has helped. Allen

 

Well WOW! thats good to hear, i would consider waiting to get mine coated then. Was it really the biggest SOTP mod that you did? Could you really tell the difference, well that might be a stupid question cause thats probably the only set that you have put o the car. What kind of gaskets did you use? the SLP gaskets? I dont really want to use a different set cause they would cover more than what needs to be covered...know what I mean?.....

I cant wait to get mine on cause then I can finish putting the stuff back together since everything kinda ties in with the headers...

 

I used the SLP installation kit which included the gaskets. Trying to remember that far back and the sequence but I did some mods to the intake like the SLP cold air kit, SLP runners, 52MM TB, Edelbrock TPI intake and some other things. Could not decern to much difference with those mods but I'am sure I picked up some HP. However when I installed the SLP exhaust system I noticed a considerable improvement in power. Could be that the intake mods were being choked by the stock exhaust system. A little later I had Chet Herbert regrind the stock cam and I installed the Brodix aluminum street heads. With the Brodix 68cc chambers I lost some compression down to around 8.9:1.
In January I'am going to finish off what I started. I will install some flat-top pistons an raise the compression up to around 10.1:1 maybe 10.2:1 at most. I'am going with the ZZ4 cam as it fits the mods and heads I have. Will do a good port match on the intake parts, siameese the SLP runners a little more and have a custom eprom burnt. I had it run on a dyno a couple of months ago. They started the dyno run at 4200RPM for some reason. Anyways it made 256RWHP and 310RWTQ. The peak torque would have been a bit higher an lower on the RPM curve. I will post the results after I do the rest of the mods. Allen

 

True what 1989Rs says about cracking.When I buy mine used slp tri-y's,they have crack at primary tubes.

 

Actually 1989RS I believe the reason mine are or were cracked is because the car was dropped on them and the y pipe bent to hell and I had to straighten them and reweld them. Another possible reason is they were in a car fire and the car under the hood was completely gone. I picked them up for 50 bucks cleaned them up and rewelded were needed. Before I had these on my car I had edelbrock headers and my car sounded much higher pitch and more annoying to me but after I put these headers on the note of the exhaust changed ALOT.

 

here is a picture of the headers after me and john got finished with them.

 

Looks sweet after you got them fixed. So do you like the tri-y's?

Im going to send mine to ASC after Christmas and get them coated the headers and Y coated and polished.

I test fitted them today and they droped right in, no binding or anything. Im going to have to cut the end of the Y pipe off and fab up a pipe to go to or thru the cat though...the 4 bolt flange on the end wont connect to what I have now....what does that connect to anyways?

and after seeing the pic above I see what I have to do.

 

so... can i have those headers wishmaster? please?

 

Hey firbird!

What kind of ground clearance issues do you havw with these?
What plugs do you run?

I don't remember what heads you have, but what about plug access, etc.

Think I might get some of those if people don't outbid themselves.

EDIT:
His LAST SET.
NO way would I pay that much

 

Smithtc............email the guy and see if he has another set...I see that set went for $600 and you tried to bid on it.........I think the guy will sell them outright for $500 if he has anymore...WOW I cant believe the bid went that high......

 

I didn't bid on it.
I emailed him before bidding was done...when price was still at $400. LAST SET.

 

I am sorry if I did not catch your response fast enough. If it still helps any I use just normal ac Delco in there I had a lot of other kinds so far with these headers and have not found one that really would not work. I can get to them all pretty easy. The biggest annoying thing about these headers is how close the bolts are to the primaries because they are not dinged in on each side for extra clearance and these headers are thick! I have vortec heads on right now.

I hope this helps you out.

 

And one more thing ground clearance. I have sport line springs on and it has dropped my car a lot and I really don’t scrap the headers much at all if any. The person who had them previous to me did however dent one portion pretty good but he must have been doing something really wrong to do that. Ground clearance is good better then edelbrock ones I had.

 

Boy am I glad I got his second to last set for $500 outright. Got them on Thursday and they looked great. Sent them out to ACS to get coated Friday. Can't wait for the damn snow to melt, only like 4 more months in upstate NY. Will post pics when I get them back from coating.

 

Please do cause Im sending mine to ACS next Friday to get coated. Are you going to have the Y-pipe caoted also? I am.

Whats the price he is charging you?

Are you leaving the air tubes on? I still need to cut mine off and grind down some of the welds on the insides of the headers ports....just piece of mind makes everything smooth on entry.....I would rather do that before getting them coated.

 

I'm getting them coated head to toe. I had emailed ACS (Jimi) a few times, and quoted him the price listed on the post that is linked to their ad ($140 for the shorty headers, and $50 for the pipe) and that does not include shipping. They said should that should be $20. So around $210 coated and shipped. If they give you any hassles just make sure to mention that you saw those prices on thirdgen. Apparently it's a significant savings for us, as their normal prices are $175 and $75 plus S&H.

And for anyone curious, they bead blast and then acid prep all their parts, and their coatings are thin enough to coat even the threaded surfaces (ie inside of 02 sensor bung) which is better for flaking and rust prevention per JIMI at ACS. Also he mentioned that one of our board members is testing a black finish for him, apparently many black coating products end up turning whitish after heating, and a new company promised him their product will not whiten so if anyone wants a black finish you can ask him about that.

Otherwise, leaving air tubes, other than a bit of clutter and minimal weight I don't see any problem leaving it, as I said before I try to leave my car as stock appearing as possible.

 

I have them. I like them. I wish I had an extra set so I could engine dyno test them for cylinder distribution.
I've had the air tubes crack. Then I got so fed up with it that I just cut them off, tapped, and bolted .

 

did any of the slp try-y's come without air tubes? i got mine at the junk yard and they have been already hacked or just did not come with them. it has the hole in the flang were the tubes would be for them but not in the header tube, someone could have just did a very good job with them not sure.

 

when I originaly ordered mine, They came without AIR tubes at my request. I have since sold them to Dyno Don a month ago
.

 

I like those alot. I wonder if they would fit my B-body. Id like to check some bone yards to see if they would fit my car and come close to my transmission crossmember.

What years did they come on camaro's?

 

Good luck finding them at any junkyard. The were avaliable I beileve starting in '89 as an SLP option and not common, or as a GMPP add-on aftermarket. Probably be able to find Bin Laden before finding a set in good condition at a bone yard, unless you find Maro/Bird heaven.

 

That one had me laughing out loud.

Ok, I see the Florida posters on here are pretty far (i.e. panhandle) and too far for a road trip. I got too much work right now. 86 IROC are you close to the Orlando-Gainesville area?

If not, I'm just going to measure any 3rd gen camaro to check your clearances and see if they match mine through an inductive approach.
