Headers for my 91'R7U/1LE. Headers that FIT!!!!!! Not headers that the ad hype proclaims to fit, but actually fit. I'm pulling my LB9 & T5 out and replacing with new ZZ6 350 (carbed) and 6 speed. I really do not want to put the stock manifolds on to it. I will be putting in new motor mounts regardless of the original's condition. Y pipe **** i can deal with i just want headers i dont have to smash and bend and that wont crack or fall apart in 6 months. Everytime i find an interesting set i start investigating and they usually get shot down in reviews/threads/posts whatever. This is getting frustrating. Any help would be cool.

I'm using Hooker 2055s with their y-pipe in my '91 Z28 with a (mostly) stock 305/T5. Only issue I see is that one of the brake lines rides awfully close to the headers. I don't know if you saw this thread, but it did influence my decision: https://www.thirdgen.org/forums/exha...055s-come.html

Now to be fair, I have to retain my emissions (so you might not need AIR tubes) and I haven't installed the full exhaust yet (it ends at the y-pipe). It's also a royal PITA to install/change plugs, but I fee like that is the case with most headers. Let me know if you want to see pictures of anything.

Hope you find a set that works!

Thank you, yes I saw that and they seem most favorable so far. I have no emissions to worry about. Cut the cat out long ago. Sure! I can't turn down pictures.

I'm running the Hookers on my 91 also. The only fitment issue I had was getting the head and Y pipe flanges to line up and not leak. That requires a bit of fiddling. I got mine second hand from somebody locally. So the price was right....otherwise I would have gone with Dyno Don's setup instead. I believe his uses a ball flange and a 3" Y pipe. The Hooker setup has a smaller diameter Y pipe than Don's. 2.5" if I recall. I'm running them on a 305 T5 car also. Do yourself a favor when you go to install them and get a set of shorty plugs, wires with 90 degree boots and set of plug boot insulators. The wires/boots run real close to the hooker headers.

I second this, shorty plugs and 90 degree wires are almost a requirement. I'm looking into a set of insulators as well. You are correct, the Hooker y-pipe has 2.5" inlets/3" out. Probably fine for a 305 (I'm running a TPI 305 with a mild cam).

I'll get some pictures tomorrow!

Look again, the Hookers are not really 2 1/2"

You would have to cut them back to make them 2 1/2" they are not even 2".

Interesting, I hadn't tried to measure them (I'm just going off the product listing) but now I'm going to pull the y-pipe and take another look. Those are the 2055s?

EDIT: Ahh, I found the post that originally came from and I see what you mean now. The flange itself is nowhere close to 2.5", but it can be widened up a bit. Thanks!

Well, I neglected to take pictures over the weekend but I do have a couple old ones that show the driver's side header.

Clearance is a little tight around the brake lines but I managed to move them a little further away. Also worth noting is that I don't have any HVAC stuff, so I don't know what clearance will be like on that side of the car.

I hope that helps!

thanks guys. Still undecided.

The stainless obx headers are the best bang for the buck right now. I have the 1 3/4" long tube ones. They also make 1 3/4" shorty headers.

Found a set of used ones recently pulled out of later 3rdgen camaro. No airtube holes. Also thru in a new y pipe that matches them up to where my cat used to be.

Nice, glad you found something that will work.

I feel your pain. I read the whole exhaust/header thread about a year ago and doing it again now. On the same issues as you. Great thread. I know Dyno Don's is the best but keep other options posted in thread for most recent header/Y-pipe options. Thanks.

JTV

What does the rest of your system look like? What's the fitment issues on the long tubes you have?

JTV

Love this set up. Gonna have to pull the stack out from under the pillow.

I looked on the OBX website, and couldn't find headers for third gen, only 2nd and 4th, did you get your headers direct or from a dealer?

Thanks

These are the 1 3/4" stainless long tube headers:

http://www.ebay.com/itm/STAINLESS-ST...pV3RLI&vxp=mtr

For under $300. I have them on my supercharged 412". They are fantastic.

They also have these shorty headers, also stainless:

http://www.ebay.com/itm/OBX-Exhaust-Header-86-90-GM-Chevy-Camaro-Firebird-305-350-Ci-Stainless-/172257878913?vxp=mtr
These I'm confused on. I've not actually had a pair in my hands, but they are listed as 1 5/8" but I'm told that they measure out to 1 3/4". The long-tube version is sometimes listed as 1 5/8, or 1 1/2" but are always 1 3/4"..

Nearly $600 for shorty headers is a little expensive, even if they are stainless. The long tube headers are the way to go. Whatever you do though, don't buy mild steel headers unless they are $150.

Thanks... from the research I've been doing, it seems long tubes might be a pain to install on my '83 LG4... it's stock... what do ya think?

anesthes

iTrader: (12)

Oh well, my intent wasn't to suggest installing headers on a stock engine. Especially an LG4.

When I'm responding to posts I'm assuming the person is swapping out the old, tired engine for a new one. The OP for example was installing a ZZ6.

But beyond that, I found them quite easy to install on my Formula.

-- Joe

bubbaz28

Thanks Joe, I really do appreciate the help, and I don't mean to highjack the OP's post. Yeah, I still have the original LG4. That's why I'm going for replacing the exhaust first. I'm hoping to find some headers at a decent price.

Alaska Hwy 1Le

No worries dude i don't care or mind anyone hijacking my posts.
I just wound up getting used headers for $150 from a Camaro/Firebird junkyard that they pulled out of some thirdgen that was smashed. I don't even know what brand they are but whatever they are still better than putting the original 305 manifolds back on. Sand blasted for a sixpack and $20 for can of headerpaint and they look like new.

Haha, nice! A guy about 3 hrs drive from me just sold a used set of Dyno Don's... sorry I didn't jump on that one. I might just get a new set of 2205's.

Those headers are $119 new:

https://www.summitracing.com/parts/sum-g9005

The stainless version is around $135:

Then the Y-pipe is another $125 or so.

The Hedman 68470 isn't a bad choice for a stock motor. 1 5/8" primary. I ran a set on a 560hp car about 10 years ago.

Alaska Hwy 1Le

I live in northern canada so that $119 would turn into $200 or more once you add shipping, customs, dollar exchange rate, and 14% tax. I don't and won't buy anything off Ebay.

Alaska Hwy 1Le

So the $135 stainless are charged out at $178 cdn plus 14%tax = $203 plus $89 shipping which is actually $101cdn for shipping.= $304 cdn by the time i see them.

That's too bad. Must be tough in Canada - high taxes, no handguns, and now I hear they are banning pitbulls.

You may have already noticed the tube is quite close to the starter (especially if you run a large starter). You may want to get one of those blankets for the starter to avoid hard starts when hot. I ran those headers on a car back in the late 90's and I had a lot of hot start issues.

Thanks u bet I'll get a blanket for it. Is there any benefit to wrapping the pipes? See that once in a while.
Ya Canada is a pain in the rear when buying anything. I saw a new z06 vette at the dealer and the price was $128890😥 plus the mentioned 14% sales tax. New camaros are $50000-$80000 depending on model.
Pit bulls are only banned in a few **** cities. Where I live there are more guns & pet wolves than pit bulls lol.
