I want to get some headers for me brumby and someone said that the stock headers of an old 84 l series have larger pipes. this true? or what other options are there?

There is a mob who make "extractors/headers" for the ea 81, just go to an exhaust or performance shop and they should be able to look it up in a catalog, i did and i bought some, didnt notice any real gains it did seam like the powerband had changed minutly but maybe i was dreaming,

Price however was about 250ish and i dont think it was worth it, up to you tho

I have heard that before. I suppose its a bit of a waste o cash to fit a supposed enhancement that doesn't enhance anything. Good call. Ta

have heard it is the EA82 header pipe is bigger dia. try a second hand cheapo to find out !

That's odd.
Did you upgrade the whole system or just the header pipe?

If I can grab a cheapy ea82 header set then I'd put em in. Always worth a try if it doesn't cost the earth.

Bought the headers brand new and had them fitted with a 2" pipe with a hot dog and straight through muffler with a 3" stainless tip, deffo flowed well but maybe i didnt have enought back pressure hense the lack of noticable power gain

A 2" system should haven't had any adverse effect on back pressure, as long as you don't go bigger than 2.25" you should be fine.

yea thats what it had, then it got stolen, then found burnt out
now the headers are on my new ute with the stocko exhaust and yea no difference
