Look like the same company to me, based on the flange.
But, not sure what company that is. What is the OD of the primary pipes? If 1-1/2", I'd guess Flowtech. If 1-5/8", then I don't know, because they don't look like Hedmans or Hookers.
I don't recall seeing that #6 pipe routing. Perhaps we can get someone to chime in that recognizes it.
Good luck finding a y-pipe if they aren't Hedmans or Flowtechs.

Those are deffintely not flowtechs. Flowtechs don't have the ball flange collector or the little loops on the flange. My geuss would be hedmans, but I didn't think they had that type of collector. Did you happen to measure the primary size?
I forgot to mention, are you sure that they are for 3rd gens?

3 inches is the outside collector diameter. and 1 3/8 is the smaller tubes...measured at the part where they touch the heads.

inside diameter is a hair off of 2.5 inches....i do not know anything about these headers, as they came on the car....the guy didnt tell me, and hes in the army now, so i cannot contact him. I doubt they are 3rd gens...cuz he put a carbed 350 in it in place of the 305 tpi....anyone else know???? I am desperate to find out

Was there a y-pipe that came with them or did the guy just run open headers. Or were they not installed and he just gave them to you? They do follow the same primary routing as my flowtecs but there are too many things different on those than mine. That is unless flowtech had a previous design that they replaced in favor of the ones I run. My only other geuss would be dynomax. There are better pics of flowtec headsr out there. A quick search should give you some results.

Upon further review...
Looks like the Blackjack/Dynomax flange.
I agree that it appears the factory y-pipe was modified to fit the headers. They probably flattened the pipe under the pan for ground clearance. Most likely won't be a severe penalty to performance, although a proper round one would flow better. Getting rid of the pipe from the "Y" to the cat, replacing with 3" mandrel and then 3" all the way back would probably make more difference.

Yep, Dynomax headers.... Just about as useless as flowtechs. Hell, the flanges on those aren't even as good as the flowtechs, and mine were warped when I took them off the motor.

My Hedmans look almost exactly like that header with the AIR tubes up there... except I have no O2 bung or AIR tubes.
I know they are Hedman too, because its got the steel "Hedman Headers" badge welded to one of the primaries. Hookers should have that too right? Why wasn't that mentioned yet?

speaking of flowtech headers do you guys think these are ok headers? by flowtech they are 1 1/2 primary tubes and 2 1/2 collectors. is there really that much of a difference from 1/2 to 5/8?

thoes deff. look like flowtecs. The flange might not match up, but I am 99% sure that thoes are flows. That one header where the primary runs above the rest of them, thats what tipped me off as soon as I saw them. Look on ebay, they sell them all the time. as a matter a fact...
these are flowtecs. Only thing I see different is the mounting flange and that one's y pipe flange.

I think those are these:
Excuse the digital photo of a photo! In a hurry!
According to my instructions, they are DYNOMAX headers. The code should be on the collector just above the flange. It should say 098.

Yep. I think they are! Here is a dig. photo of the instruction sheet. Ironically, I needed a Y pipe for these, but made my own (and then had it chrome plated!). Not because I couldn't find one though (I didn't look). Quicker to make my own than wait for them to come from the states to the UK.
Hope this helps.
Andy.

I have e-mailed them (Dynomax) about a Y pipe. If they have one, I could do with a spare also! I will let you know.

Whether Dynomax & Flowtech use the same source - who knows these days...

I was talking about the pic below this quote. They are Hedman # 68470, You can see the tag on the header on the left hand side on the #1 tube.
THE PIC ON THE NEXT REPLY DOWN ARE DEFINITLY FLOWTECH.
THE CERAMIC COATED ONES BELOW THAT ARE DYNOMAX.

Hi 85camaro350.
I got a reply from Dynomax on those possible Y pipes. Here it is:
........................................................................................................
"Thank you for your inquiry for Dynomax Exhaust. We appreciate your
interest in our products. In regards to our headers with a 098 collector
code, these are a Standard Series, non-emission header and unfortunately we
do not offer a y-pipe and the stock emissions system must be fabricated
onto the headers.
If you have any further questions, please feel free to contact our tech

Thank You,

Hi Dave.
Good advertising!
Now, I may be interested in your products. I have a 1991 RS Camaro with a 1977 350 in it. No emissions, no CAT, and carbed. How much for headers and Y pipe? What about shipping to the UK? Are they coated?
Thanks.
Andy.

Thanks for the prompt reply Dave! I am now seriously considering it!
When you say "have you considered running without a Y pipe", what exactly do you mean? i.e How?
The car has airbags fitted and runs loooow, so whatever it gets, must be well tucked in. And look damn good. See photo below.
Thanks.
Andy.

Would these headers and y pipe fit an airbagged 86 camaro with a 305 and 700R4? This car has also got no CAT and emissions stuff, and I will eventually get a stainless cat back system on (polished). Does the Y pipe end as a pipe or a flange? I will have to fabricate or buy a suitable stainless section in place of the CAT (polished of course) - any advice?
It's highly possible that my bank account will get a hammering on these things very shortly.
Thanks.
