Yeah not sure mate, all I know is this engine was in a boat before I bought it. It had this sticker and a barcode on it but I can't find any reference to the code on it "EA81G7"

N/A EJ Unequal length headers are readily available on ebay starting from $250

Once I get a better video I'll uploaded it to my youtube channel, the video on facebook is to dark but sounds good, one of them is a hillclimb not far from where I live and I had a bit of fun. until then here is 2 videos from youtube to wet your appetite, unfortunately not EA's but you'll get the picture.
I have a set of the ebay headers on my brumby and they have cracked at the joins twice. while they sound great there are way too many joins and pipes for my liking. the way you have made your headers is how I would want a set made for an EJ motor. They are simple, elegant and efficiently made.

Fair enough mate, interesting because I was thinking of making a set from mandrel bends but that would have many joins.

Pretty sure that's an imported EA81 engine, so it probably didn't have that pollution crap on it.
I think mandrel bends wouldn't give you that much more power that you'd need to worry about it. Keep it simple.. which worked so well for the EA81 for many years

I was thinking it may have been an import too.
I was thinking mandrel for ease of making more as I don't have a pipe bender but stuff it, I'll buy one

I like the way you think

That's the spirit
I'd take a couple of sets if you decide to make EJ ones

Nice mate.
For those that have to run a cat converter it'd be good if you could incorporate a generic cat unit into the system roughly where the old one is placed. Then it should be a straight bolt in system for those that need a cat converter there.
Not having one on a vehicle that should is a big fine if you're busted...

I guess the jury has come to a decision, pipe bender shall be bought. I think I'll stick to the simplicity of the EA for starters before moving on to EJ's. Cats on the EA82 are part of the header so it would make it pricier to make unless, like you say use a readily available generic cat with flanges either side that'll bolt straight up.

DAWN is a good old Aussie brand is it not?
Won't a heavy duty pipe bender crush exhaust pipe? Or filler with sand first !

I have an old Aussie Dawn Vice.
You do get a bit of crush, if you want mandrel type bends you do fill the pipe with sand first and then weld caps to the end before pressing.

Yeah I'm talking about a single inlet cat like you find on every other vehicle! Use one that's really common and easy to get

Yep, V6 Crumble door should be plentiful at the wreckers.

At Subinats today and a nice supercharged Forester started up his engine with the bonnet up and started giving it a few revs for the crowd, I decided to start my EA81 in the 77 two door and do the same but with the bonnet down, had few people come over saying Wow you have EJ in there!? They didn't believe it was a n/a EA81 until I opened the bonnet LOL

I think the accusation was
" that's not a push rod 1600 in there "
Fuji me dear readers.... this did not sound anything like 'just' an EJ once above about 1500 rpm - close your eyes and hear an early WRX parrrping along - flippin' awesome mod.
Hearing and seeing was believing !! Nearly giggled self to lightheaded excitement when i heard it.
Mister Fisya is taking orders ....

Interesting character that one........
I'm interseted to hear what the short stroke 1600 will sound like with UEL headers in my 1600 coupe, when I had the same muffler and stock headers on the 1600 it sounded like a 2 stroke Detroit diesl LOL.
I've also been trying to figure out how to do UEL headers on the 1400 coupe with the duel port exhausts...........

You trying to figure out...I been trying to figure out how you got 100kph in 2nd gear of a L Series 5 speed behind that EA81...whatever combo, EA81 or 82 , 4 speed or 5, I can still only manage a fanging 80 , a true 80 kph in second. Now, i spied 185.75? 13's . they'll tell lies at the speedo end ......

Speedo is pretty much spot on. It's actually a MY GLF 5 speed box, not sure if ratios are different. I'm curios what the revs are as I don't have a tachometer but, its absolutely reving it's tits off, my dad was shaking his head on the way down to Subinats every time I did it LOL.

And come to think of it, with the bigger tyres it would be actually be going faster than the speedo reading.......
