Hi Jeff,

If you are going to spend decent money on headers, I would suggest at least looking at these store.summitracing.com/egnsearch.asp?Ntt=thorley&N=700+4294918680+4294908331+4294908282+115+4294924702&Ntk=KeywordSearch

Cyclone long tubes (ground clearance???): mustangsunlimited.com/itemdy01.asp?T1=DY22+01&Category=&catkey=EMUSTANG
Hedman long tubes (relatively expensive, ground clearance???): mustangsunlimited.com/itemdy01.asp?T1=86304+01&Category=&catkey=EMUSTANG
Again, definitely open to suggestions of headers that will work on my car. These are just some that stood out to me as possibilities when I looked over the search results I got from MU. My criteria are: ceramic is a must. Seems like relatively equal length primaries is important, so would be nice. Top end performance isn't a big concern - I rarely get near 4000, much less higher (this is a street car), so low end torque is much more important to me. Willing to pay to get a good product, within reason (would need a great reason to go beyond about $500).
Other info about my car:
- 289, stock cam
- edelbrock performer intake + carb
- manual transmission (T10)
- power steering
- don't think this matters, but no power brakes
- may want to lower the car just a bit in the future (like 1 inch)
- not concerned about fitting with existing exhaust parts - I'm planning to replace the whole exhaust system from manifolds to tips

I'm starting to believe I should get better performance out of long tube headers. But then again I read somewhere that you hear a lot more engine noise with them. And then there's the question of what fits with minimal mods (hopefully none).
I did a little googling to try to learn more about this stuff and came up with what looks like a couple of good articles. The first one essentially says shorties aren't real headers. Thought I'd pass these along for anyone interested and to see if they can generate some discussion.

I am considering installing headers plus new mufflers and tail pipes very soon. I don't know much about headers, other than that I should shell out the extra money for ceramic coated. What are the advantages and disadvantages of shorty headers vs. full length? I am looking at the Hedman headers shown at the link below. Any advice (including other brands if you prefer them over Hedman) appreciated. I have a 66 coupe with a 289, and manual transmission (converted from automatic by PO).

P.S. I'm looking at Flowmaster Super 40, or 50 Series Delta Flow, for the mufflers. Any thoughts on these mufflers would also be appreciated. I want a great sound outside, but not a lot of interior noise. That has me leaning toward the 50's.

I agree, and I will post it. Yes, I know I'll have to get the drop bracket,
and apparently I need to convert my clutch equalizer bar to the hipo style
(though from the pictures I've seen, I don't see how the hipo one gives any
more clearance).
No need to apologize - I appreciate that you shared the info about the
headers to begin with because I wouldn't have come across them otherwise,
and despite the higher cost, they do look like great headers to me. I have
yet to tell my wife how much they cost, and since I'm replacing the entire
exhaust system, she's not going to be too excited! I'll have to sell her
hard on the quality!

If you are going to spend decent money on headers, I would suggest at least

Look at the DTE-289YC (ceramic) or DTE289Y (nickel chrome). I have only
torqued the bolts once since install and no leaks. I do still check them on
occasion, but thay are staying tight. Remember, the thicker the flange, the
better. I've had a bad experience with Hooker's and Headman's 16 gauge with
1/4" flange. They rusted at the collectors and eventually blew a hole
through them. They were even ceramic coated. Although I did drive it in the
snow in Denver...LOL Now that I moved to Nevada, I purchased the Thorleys
for the 14 gauge primarys and the 3/8" flanges. Mine are not ceramic coated.
No need......have plenty of room in the engine compartment for ventilation.

So I am looking to make a decision now. I'm looking at what Mustangs
Unlimited has (I'm open to other vendors as well, and I'm wondering if it
might be better to order thru a muffler shop, even if I install them, just
for the ability to return them if there are any issues with fitting -
shipping something like that can get pretty expensive!).

Again, definitely open to suggestions of headers that will work on my car.
These are just some that stood out to me as possibilities when I looked over
the search results I got from MU. My criteria are: ceramic is a must. Seems
like relatively equal length primaries is important, so would be nice. Top
end performance isn't a big concern - I rarely get near 4000, much less
higher (this is a street car), so low end torque is much more important to
me. Willing to pay to get a good product, within reason (would need a great
reason to go beyond about $500).
Other info about my car:
- 289, stock cam
- edelbrock performer intake + carb
- manual transmission (T10)
- power steering
- don't think this matters, but no power brakes
- may want to lower the car just a bit in the future (like 1 inch)
- not concerned about fitting with existing exhaust parts - I'm planning to
replace the whole exhaust system from manifolds to tips

I'm starting to believe I should get better performance out of long tube
headers. But then again I read somewhere that you hear a lot more engine
noise with them. And then there's the question of what fits with minimal
mods (hopefully none).
I did a little googling to try to learn more about this stuff and came up
with what looks like a couple of good articles. The first one essentially
says shorties aren't real headers. Thought I'd pass these along for anyone
interested and to see if they can generate some discussion.

Subject: [CM] headers: shorty vs. full length
I am considering installing headers plus new mufflers and tail pipes very
soon. I don't know much about headers, other than that I should shell out
the extra money for ceramic coated. What are the advantages and
disadvantages of shorty headers vs. full length? I am looking at the Hedman
headers shown at the link below. Any advice (including other brands if you
prefer them over Hedman) appreciated. I have a 66 coupe with a 289, and
manual transmission (converted from automatic by PO).

mufflers. Any thoughts on these mufflers would also be appreciated. I want a
great sound outside, but not a lot of interior noise. That has me leaning
toward the 50's.

I agree, and I will post it. Yes, I know I'll have to get the drop bracket,
and apparently I need to convert my clutch equalizer bar to the hipo style
(though from the pictures I've seen, I don't see how the hipo one gives any
more clearance).
No need to apologize - I appreciate that you shared the info about the
headers to begin with because I wouldn't have come across them otherwise,
and despite the higher cost, they do look like great headers to me. I have
yet to tell my wife how much they cost, and since I'm replacing the entire
exhaust system, she's not going to be too excited! I'll have to sell her
hard on the quality!

Good point Jeff....I see that too. I would trust the Thorley book more than
Summit. But you never know. I don't have mine yet, either, so I couldn't
tell you. When you find out for sure......would you please post that info? I
see the #268 straight tubes have the 1 5/8" with a 3" collector and the #289
Tri-y's have the 1 1/2" with 2 1/2" collector (according to the Thorley
book). Kinda makes sense for the Try- y's to be smaller, having a smaller
collector. Did you catch the code #8, it says "Vehicle with external power
steering slave cylinder might require bracket". Sorry for not having a
positive answer for you. I do have the 1 5/8" on my P/U and they do have the
3" collector. Hopefully, someone has a set in the forum.

Unfortunately it's Friday night so I can't just call Thorley until Monday,
so I thought I'd check here. Anyone have these headers? The summit racing
site lists them as having 1 5/8" primaries, yet looking at the official
thorley pdf catalog, they're listed as 1 1/2". I'd prefer the 1 1/2" because
of my stock cam, which probably won't be changing any time soon.
Can anyone tell me with certainty what is the size of these headers?

Subject: Re: [CM] headers: shorty vs. full length
One question as I am getting closer to a decision: these headers have 1 5/8"
primaries. I've heard it said that 289's should ideally have 1 1/2"
primaries (particularly if it has stock cam I'm guessing?). How much of a
difference does that 1/8" make? And could it be that the story is different
for tri-y's vs. other headers due to the presence of secondaries? I'm trying
to decide between the ruggedness of the 3/8" flange/14g tubes and the fact
that it's 1 5/8 instead of 1 1/2.
I welcome any thoughts.
Again, I *may* upgrade the cam at some point, but that is likely far down
the road due to the long list of things I want to do to my 66 in the limited
free time that I have!

Hi Jeff,
I have a set of Doug Thorley headers in my 1970 F-250 390 C.I. and soon to
go on my 69 Sportsroof when I get her engine finished. I really like them.
If you are going to spend decent money on headers, I would suggest at least
looking at these store.summitracing.com/egnsearch.asp?Ntt=thorley
<store.summitracing.com/egnsearch.asp?Ntt=thorley&N=700+4294918680+42

&N=700+4294918680+4294908331+4294908282+115+4294924702&Ntk=KeywordSearch
Look at the DTE-289YC (ceramic) or DTE289Y (nickel chrome). I have only
torqued the bolts once since install and no leaks. I do still check them on
occasion, but thay are staying tight. Remember, the thicker the flange, the
better. I've had a bad experience with Hooker's and Headman's 16 gauge with
1/4" flange. They rusted at the collectors and eventually blew a hole
through them. They were even ceramic coated. Although I did drive it in the
snow in Denver...LOL Now that I moved to Nevada, I purchased the Thorleys
for the 14 gauge primarys and the 3/8" flanges. Mine are not ceramic coated.
No need......have plenty of room in the engine compartment for ventilation.
:-) As for your clearence around your T-10 and power steering, you might
want to call Summit and ask a "Tech". Note the quote on tech...LOL

Subject: Re: [CM] headers: shorty vs. full length
So I am looking to make a decision now. I'm looking at what Mustangs
Unlimited has (I'm open to other vendors as well, and I'm wondering if it
might be better to order thru a muffler shop, even if I install them, just
for the ability to return them if there are any issues with fitting -
shipping something like that can get pretty expensive!).
I get the sense from some of the discussion here that finding headers that
will fit a 66 289 is pretty tough, but Mustangs Unlimited has such a big
array of headers that claim to work for a 66 289. Do you think it's safe to
assume that any of them will work? Or is it a definite "buyer beware" thing?
Anyway, I'm looking at several in particular. Some shorties, and some long
tubes (all ceramic coated). I'd be curious to get some feedback on these in
terms of quality, whether they will fit, performance, ease of installation,
ground clearance (my car's not lowered now, but I may lower it just a bit in
the not too distant future), etc.
Tri-Y (these seem odd because they seem to have "pre-collectors", but I
think these have been mentioned here in the past, so figured I should throw
them out there):

<mustangsunlimited.com/itemdy01.asp?T1=S1MS9430RC+01&Category=&ca
tkey=EMUSTANG> &Category=&catkey=EMUSTANG
Clippster shorties (there's a huge difference in length of primaries though,
which as someone who is new to headers concerns me):

<mustangsunlimited.com/itemdy01.asp?T1=H84301+01&Category=&catkey

Hedman shorties (same concern as clippsters):
