Does anyone make a 4 into 2 header?

[Mason357]

I would like to know if there's a 4 into 2 exhaust header available.

MaxMoto in the UK, Black Widow in the UK, and Delkevic still make them.
Brocks, Yoshimura, Akropovic, Vance&Hines, Ti-Force, and HMF all made dual headers at one time, but all of these have since been discontinued.
Brocks, Yoshimura, and Ti-Force had some titanium dual outlet headers too.
You can find new old stock on occassion, and there are still alot of good used ones for sale.

Yep...discontinued...and there is no full dual header, or full dual exhaust listed in the link you posted either.

There are actually a few more brands of full dual exhaust for the gen1 and gen2 still available on Webbike Japan, but I don't know if you can order the just the header.

(a few full duals for the gen3's on there now too)

a minute ago i phoned to jamparts, THE akra-dealer in europe and he lead me to this page

here u can find all special parts 4 the exhaust - when on page scroll down to the button "spare parts" .

lil hint from jamparts
the 4 in 1 collector they offer for the gen1 is built 4 the gen2 what (quotation jamparts) causes a lil necessary change at the radiator - it has to be mounted a bit more to the front.

with the spec. art. numbers from jamparts it shouldn´t be THAT difficult to get the "pipework, etc." from an akra-dealer in the us.
u have to look for a dealer - that´s it.

or join ebay and co. for a preowned 4 in 1 akro downpipe - guess it will need a lot of patience but at least u´ll find one
gen1 or gen2 - shouldn´t matter - both should be usable

don´t ask in germany for delivery to the us - it would be horrendous expensive.

No, not a 4 into 1....the OP is looking for a 4 into 2 Dual outlet Akropovic header...which I know they made, I hade one with cf mufflers on my gen2...but they are now discontinued.

uuuuuuuuuuuuups - i read wrong - sorry for all my posting

so i turn my questioning

why not to use the original downpipe( + collector 4-2) ?

there should be enough on the market ´99-´01 and ´02 - ´07 for cheap money .
